Full textAbstract:
This thesis is analysis-based survey in which our task was to find out the suitability of
IEEE 802.15.4 for the RFID systems in terms of power. We studied the different RFID
systems. We analyzed the IEEE 802.15.4 to see how much this protocol can facilitate the
RFID application, but we just considered the 2.4 GHz physical band as Free2move uses
this band for its RFID products. Since semi-passive1 RFIDs are the closest competitors
of the active RFID, so we also compared the IEEE 802.15.4 with ISO 18000-4 (mode2)
to find out their pros and cons.
We also tried to evaluate the hardware architecture proposed by Free2move. We
compared proposed hardware components with other competitors available in the market.
The main point of focus during hardware evaluation remained its power efficiency. As
concluding part we have proposed an idea for using the IEEE 802.15.4 standard in semi-
passive RFIDs.

Full textAbstract:
Ultra high frequency (UHF) radio frequency identification (RFID) systems suffer from
issues that limit their widespread deployment and limit the number of applications where
they can be used. These limitations are: lack of a well defined read zone, interference,
and environment sensitivity. To overcome these limitations a novel receiver device is
introduced into the system. The use of such device or devices mitigates the issues by
enabling more "anchor points" in the system. Two such devices exist in industry and
academia: the Astraion Sensatag and the Gen2 Listener. The drawbacks of the Sensatag
is that it offers poor performance in capturing tag signals. The Gen2 Listener is based
on the expensive software defined radio hardware.
The purpose of the thesis was to develop a receiver that will enable several new
RFID applications that are not available with current RFID systems. The receiver,
named ARR (Augmented RFID Receiver), receives tag and reader signals, which are
decoded by an FPGA and the results are reported through Ethernet. This device is
central to the augmented RFID system. To show the suitability of such an approach, the
performance of the implementation was compared to the other two outlined solutions. A
comparison of the read rate and range of the implementations were the defining factors.
The analysis showed that the ARR is capable of receiving tag signals with a read rate of
50% for passive and 66% for semi-passive tags at a one meter distance and is capable of
receiving tag signals at a maximum of 3.25 meters for passive and 5.5 meters for semi-
passive tags, with the reader being within 8 meters of the ARR. Two applications were
implemented to showcase the ARR: an RFID portal and protocol analyzer.

Full textAbstract:
This study investigates the impact of organisational and technological factors within pre-adoption, implementation, and post-implementation phases of RFID system deployment. In the pre-adoption phase, the study examines factors that drive and hinder organisations’ decision to adopt RFID. In the implementation phase, the study investigates the impact of organisational factors (business size, strength of culture, and business process re-engineering) on influencing the implementation processes of RFID. In the post-implementation phase, the study investigates how the benefits derived from RFID implementation interact with organisational factors (business size, strength of culture, and business process re-engineering) and RFID-related factors (product unit level of tagging, RFID implementation stage, and organisational pedigree in RFID). This study was motivated by the lack of (i) an advisory framework which considers quantifiable firm characteristics and the costs and benefits of implementing RFID, in yielding advice to guide decisions on RFID adoption, and (ii) a framework that covers the complete processes of RFID project deployment (from adoption decision to benefits derived) in yielding advice to guide decisions on RFID adoption. This study is achieved using a two-phase research approach: questionnaire survey of organisations that have adopted or plan to adopt RFID and case studies of organisations that have integrated RFID into their business processes. In addition, a thorough review of existing literature on RFID in different industrial settings was conducted. The key findings from the study indicate that RFID adoption is driven by factors from technological, organisational and environmental contexts and that the adoption, implementation and benefits of RFID are influenced by organisational culture strength, business size, and BPR. It was found that strong cultures, organisational size and BPR are all positively correlated with RFID adoption decisions, implementation and benefits. Potential contribution towards the existing body of knowledge is through highlighting the significance of organisational culture strength, business size, and BPR in providing a platform in which RFID will be accepted and implemented successfully to achieve maximum derivable benefits.

Full textAbstract:
This thesis addresses concepts of implementing a RSA cryptosystem on a passive RFID tag. With a limited number of public key cryptosystems on passive RFID platforms, the proposed algorithm makes use of Montgomery multiplication primitives to reduce the amount of computation required on the power constrained tag therefore making the proposition viable. Public key cryptography is being suggested for next generation RFID systems to reduce the number of possible attack vectors native to this type of technology. By estimating the area, power and time constraints of the RFID platform, it was determined that the area constraint was the critical variable in determining the maximum implementable security variable. Although the application of this algorithm has been targeted for passive HF RFID platforms, the algorithm could be used in other low power, sized constrained applications.

The School of Electrical, Electronic and Computer Engineering of the North-West University is conducting research about RFID (radio frequency identification) medium range reader systems for an international company, iPico. The focus area of the present research is the development of a robust tag detection algorithm for noisy environments.
During the past three years a digital detection algorithm was developed. This digital detection algorithm delivered significant improvements in detection of RFIDs over its analogue counterpart, especially in noisy environments. However, the digital detection algorithm was found to be very sensitive with regard to data rate deviations.
Although the latter algorithm improved the detection of RFIDs, ghost (absent) tags were now also detected. The objectives of this project are, to develop an enhanced detection algorithm which is less sensitive to frequency deviations and to eliminate the appearance of the so called ghost tags.
The proposed enhanced algorithm will be implemented on a FPGA (field programmable gate array), more specific the Altera Cyclone EP1CT144C6 FPGA.Thesis (M.Ing. (Computer and Electronical Engineering))--North-West University, Potchefstroom Campus, 2009.

Full textAbstract:
Counterfeit products, particularly pharmaceuticals, electronic devices, and apparels, are widespread. They threaten consumer safety and cause huge economic losses to licit supply chain partners and governments.
Although a number of traditional anti-counterfeiting technologies, such as holograms and chemical tags, are available to combat counterfeiting, they are vulnerable to imitation or being reused. Besides, these technologies are intended to protect individual items, rather than to safeguard an entire supply chain. As such, fake products may likely be injected into the supply chain to hurt end-consumers.
Track-and-trace technology based on Radio Frequency Identification (RFID) has recently emerged as a promising tool to combat counterfeiting, because of its automatic and non-line-of-sight capability to identify massive product items. By maintaining an electronic pedigree (e-pedigree) that records the transaction information of product items along the supply chain, this approach stands out for protecting the supply chain against infiltration, eliminating theft and fraud, facilitating recall of defective products, and supporting remote authentication.
However, a number of technical and critical issues have yet to be solved for practical implementation of RFID-based track-and-trace anti-counterfeiting. These include generation of accurate initial product e-pedigree in fast moving manufacturing lines, precise e-pedigree updating in batch product distributing and receiving, and fast e- pedigree queries for remote and real-time product authentication from end-customers. Without fully addressing these issues, the accumulated product e-pedigree data would be untrustworthy, rendering any subsequent operations of track-and-trace and product authentication unreliable.
This thesis investigates the crucial implementation issues in RFID-based track-and-trace anti-counterfeiting. It firstly presents an innovative track-and-trace anti-counterfeiting system, based on which a TDPS algorithm is proposed for generation of initial product e-pedigree in fast moving production lines. The TDPS overcomes many practical issues, such as tag writing error and tag locking failure, and helps identify the bottleneck of initial product e-pedigree generation. To tackle the bottleneck, the TDPS is further optimized by incorporating a block writing method to enhance the tag EPC writing efficiency and an integration method to balance the overhead of RFID equipment.
In product distributing and receiving, a mechanized 3D scanning method is proposed to improve bulk item identification rate and enhance the accuracy and completeness of product e-pedigree. Indeed, RFID-based track-and-trace anti-counterfeiting mandates a relatively high bulk item identification rate for product authentication and e-pedigree updating. Experimental results demonstrate that the mechanized 3D scanning can achieve a bulk item reading rate of up to 98.9%, which largely outperforms the widely documented bulk reading rate (70%) in real applications.
In retailing level, the efficiency of e-pedigree queries would hugely impact on customer shopping experience and the effectiveness of track-and-trace anti-counterfeiting. A partition-based method is therefore developed to cluster product e-pedigree data to improve the speed of e-pedigree queries. This approach partitions the accumulated e-pedigree data into fixed and dynamic groups, such that queries are conducted mainly on active data, rather than on the whole historical data sets.
By addressing the above key issues, this thesis contributes to making implementation of RFID-based track-and-trace anti-counterfeiting practically viable and reliable.published_or_final_version

Full textAbstract:
The emerging technology of active RFID tags has strong potential in the areas of real time health monitoring, sorting of cargo, and large scale inventory management because of their longer communication range and larger data storage capacity. The market of active RFID is growing very rapidly and therefore there has been an increase in the number of companies engaging in this field. But very often it is found that the products available in the market are not always suited to the application at hand. To overcome this problem, off the shelf active RFID products which were reconfigurable and followed a standard PHY and MAC layer protocol were used for this work. By reprogramming the application layer protocol of the RFID hardware, these devices were made suitable for the desired application. This also allowed the RFID tags to extend their functionality by interfacing extra modules with themselves. The work presented in this thesis describes the way in which the microcontroller on board the active RFID tags and readers can be programmed so that the functionality of the RFID hardware can be changed as per requirements. It also shows that extra modules can be added to the tag by successfully interfacing an accelerometer module with the tag.Master of Science

Contactless smart cards (RFID cards) have been widely used for manyapplications such as epassport, ebanking, transit fare payment and accesscontrol systems. These cards have limited resources for performing arithmeticand logical operations and storing data along with program code. Asasymmetric cryptographic algorithms, performs time consuming complexoperations and demands more resources therefore these operations are performedin the special co-processors inside smart cards. The implementationof these extra co-processors increase the cost of smart cards.Recently a new algorithm Multivariate Quadratic Quasigroup (MQQ) hasbeen proposed for asymmetric cryptography and it is claimed that decryptionoprations are faster than already existing algorithms (RSA, ECC) [17].Eventually, a digital signature scheme based on MQQ has been proposedand it is named as MQQ-SIG [28]. In original MQQ public key algorithmthe size of private and public key was quite large in (KBytes). The size ofprivate key has been significantly reduced in MQQ-SIG scheme. Due tothis improvement in the private key size, it becomes possible to implementsigning procedure of MQQ-SIG inside contactless smart card. The fastsigning speed and simple operations performed in signing makes MQQSIGan appealing choice for smart cards which has constrained resourcescomparatively to other devices such as mobile cell phones and personalcomputers (PC).In this thesis we have implemented the digital signature part of MQQ-SIGalgorithm in Java for the 8-bit contactless smart card from the NXP familyJCOP 41 V2.2.1. These cards have Java Card Virtual Machine (JCVM)which enables limited features of Java. This is a completely original workand as far as we know there are no other Java implementations of MQQSIGdigital signature.Key generation part of MQQ is quite time consuming and therefore can notbe implemented inside smart cards. Similarly, verification part of MQQSIGutilize public key for verification of signed message. The public keyof MQQ scheme is quite large in hundreds of KBytes and therefore cannot be stored inside smart cards. These two parts of MQQ-SIG has beenimplemented on desktop computers and are not part of our Master thesis.

Kartongbruket AB has a supplier of bale pulp which is transitioning to an RFID marking of its bales. Due to this, new perspectives are requested on an RFID implementation regarding the handling of bales. This study focuses on the inbound logistics process and the pulp bale handling process. Furthermore, traceability-related problems are noted due to the fact that the current scanning methodology does not work with sufficient precision. The coexistence between the current barcode reading system and the RFID reading system is also something that is identified as topic which needs to be studied. This study’s choice of the process industry and the cardboard industry is based on a theoretical gap regarding the above-mentioned concepts and problems in this specific industry. Purpose: The purpose of this study is to be helpful to Kartongbruket AB in their upcoming RFID implementation, and to fill the identified theoretical gaps. Method: This is a case study at Kartongbruket AB. Empirics have been collected through semi-structured interviews with relevant internal actors, where the respondents have been identified using a snowball selection method. The study is of a qualitative nature and the theoretical frame of reference has been created through a literature study. Conclusion: This study concludes that RFID can be used in the inbound logistics process to make stock balances more reliable in several potential ways. In addition to this, it can be concluded that an RFID-based system can lead to a centralized traceability system in the pulpbale handling process where internal actors can gain a greater knowledge base in customer complaints cases. The study's presented implementation model may be used as a support for the upcoming RFID implementation. The study also establishes that the merging model is the most suitable coexistence model for Kartongbruket AB when RFID and barcodes are to be run together in the pulp bale handling process.

For radio frequency identification (RFID) system implementation in supply chain, there are numerous commercial and academic documents and publications available. RFID technology facilitates reading of objects without physical and visual contact with real-time data transfer. In order to provide an overview of the state of the art of knowledge development on the topic, this paper systematically classifies and analyzes documents and publications regarded as guidelines, frameworks, models, and methods on RFID system implementation using a proper selection criteria, classification method and content analysis methodology. For this purpose, documents and publications on the topic that are published between 2004 and 2015, that are easily available publically online and through libraries, and that address topics relevant during the process of RFID system implementation were reviewed. A comprehensive review of existing documents and publications is provided and business and technology requirements are assessed. Totally, sixty-seven documents are short-listed for six categories based on selected criteria, where forty documents concentrate on economic analysis and special implementation aspects of RFID and only twenty-seven documents address categories of project management, implementation from the perspective of large and small and medium enterprises, and special business domains. Accordingly, irrespective of the quality and scope of the documents, the overall number of documents is small as there are different facets of an RFID system implementation and diversities in RFID applications because of the characteristics of the technology and uniqueness of business processes and needs. Based on the findings, the paper proposes future research areas.

Full textAbstract:
In the last few decades, new vertically integrated players have appeared in the fashion industry providing their customers with lower prices and an increased number of seasons per year. In this context, the need for high efficiency levels among the fast fashion retailers appears as a necessity to survive. Since the area of Store Operations (SO) is directly dealing with processes at the end of the supply chain, boosting revenues through the increased efficiency and incorporation of new technologies in this area becomes critical. In order to accomplish that in a long-term perspective, this must be done while improving staff working conditions, customer experience in the stores and with more cost effective practices. Therefore, this study investigated how established fast fashion retailers can improve their Store Operations in pursuance of coping with growing efficiency requirements and rapidly changing technology in their stores. This has been done by conducting a case study at one of the biggest fast fashion retailers in the world. The research involved 42 different interviews with the case company’s employees and industry experts in the store solutions field, which allowed collecting both qualitative and quantitative data. Moreover, in order to analyze empirical findings obtained during the research process, outsourcing theories, including transactional cost theory (TCT) and resource-based view theory (RBV) as well as innovation theories, including diffusion of innovation and radio frequency identification (RFID) adoption theories, were used. The results indicate that in order to improve their Store Operations, the case company should first work on five areas, which include: (1) stockroom processes, (2) technology and innovation, (3) alarm systems, (4) employee morale, and (5) customer service. At the same time, it was discovered that the solutions that can improve all of these areas are: RFID that act as a security device and the outsourcing of stockroom process, known as Golden Delivery. In order to make the implementation of these two solutions successful, separate implementation guidelines must be created, both of which are presented in this document. The findings of this study have implications on both sustainability and research. This investigation contributes to the literature by giving a better understanding of the operational activities performed in the store environment of fast fashion retailers as well as the link between them and the rest of the supply chain. Moreover, the efficiency solutions presented in this document give fashion retailers a sustainable economic advantage achieved through cost savings and increased business performance, as well as, the motivation to focus on social and environmental aspects related to these practices.

The use of Radio Frequency Identification (RFID) in Real-Time Location Systems (RTLS) in asset management has been in limited use, mainly in large organizations such as hospitals and military. The research in this area is making progress and new solutions with reduced costs with greater resolution are presented by different companies that enable the technology to be used in new operating areas. This thesis is about the development, implementation and integration of a RTLS solution that enables surveillance of the position of keys. The RTLS solution utilizes RTLS hardware to receive the positions of the keys. The report describes how the RTLS hardware is selected and how the software solution is designed and implemented. The report describes also result of how the finished solution with software and hardware cooperates. The most vital problem was to create an efficient zone structure that implements the surveillance hierarchy of the keys. The thesis was conducted at a company (PAAM Systems) that offers solutions in access and asset management. The company aims to use a RTLS in an asset management application for keys. The purpose of this work is to examine the existing solutions on the market that provide a RTLS with passive RFID technology.

Full textAbstract:
This report documents the design, construction, and implementation of a differential-offset spread spectrum RFID system, to avoid the problem of anti-collision interference from multiple RFID tags. Currently in industry, this problem is handled by establishing a two way communication link between the tags and the interrogator. The proposed system eliminates the need for the excessive hardware use to create this link, and therefore drastically reduces the cost of each tag. Not only is this system cheaper to implement but it is faster, requires less power, and by the nature of the design contains an inherent encryption scheme for the data being transmitted.
Specialized RFID tags were designed and fabricated in order to produce a pseudo random code unique to each tag. The design presented in this document allowed simultaneous interrogation of up to 255 tags within one sensing environment. Once queried, the tags then modulate the incoming signal from the interrogator with their own sequence, and reflect the signal back to the interrogator. What the interrogator then receives is a combination of backscatter from all of the tags within the sensing environment. Specialized software written in Matlab and LabView uses these unique sequences to isolate the data from a desired tag away from the sea of information being transmitted from every tag. Using this system, numerous applications for experiments and measurements can be devised.
One such application this thesis focuses on is the use of this system to simultaneously measure signal strengths from multiple diversity antennas in order to optimize their position and orientation. Currently, the majority of antenna diversity measurements are taken by measuring the signal strength of a given configuration one antenna at a time. By using the anti-collision RFID system proposed above, the signal strength produced by both antennas can be measured and recorded simultaneously to provide a true representation of their combined performance. This measurement can be used to find the optimal configuration for multiple antennas.
This thesis will fully explore the theories and procedures behind creating this system, and will provide the results and analysis of its performance.

The purpose of this final thesis isto develop a model for justification and evaluation of RFID technology. RFID is a new, relatively untested, technology using radio signals for automatic identification of different objects. Our theoretical frame of references focuses on research about RFID and implementation iss ues, we also conducted case studies and interviews in order to learn about RFID. Most RFID installations of today are Pilots or early adopters wanting to try new technology. A lot of the written sources were reports from consultancy firms or suppliers of technology.
Implementing RFID in real environment gave important insights into potentials and limitations of the technology. It proved that it is difficult to achieve sufficient readability in a steel environment. We also learned that one should not underestimate the time for installation and tuning in order to meet higher readability. The project finally resulted in an iterative model for justification and evaluation of RFID technology.

Includes bibliographical references (p. 101-103).
This thesis focuses on the operational improvements in a semiconductor equipment manufacturing company (Varian Semiconductor Equipment Associates). The company faces challenges of highly fluctuating demand as well as complex and highly customized assembly, which lead to problems such as lead time control and components tracking at multiple manufacturing stages. The goal of the project is to propose an efficient assembly system with the ability of parts checking and tracking. Radio Frequency Identity (RFID) technology is introduced as the core method to treat the problems, in such a way that RFID tagged parts can be sensed automatically by antennas and identified by the system. In order to implement the system and maximize the benefits, redesign of the manufacturing process is proposed and discussed as the main results of this thesis. To achieve the goal, the current operations are carefully captured and analyzed; the RFID technology is briefly described as the basis of designing new procedures; the lean principles are introduced to refine the processes; and the simulation is applied to evaluate the changes between the old system and the new system. The solutions include three phases: 1) RFID for miscellaneous parts checking, 2) RFID for module parts tracking, 3) RFID for parts tracking in the flow line, respectively corresponding to the three problems: 1) Inefficient operation of miscellaneous parts, 2) fraudulent claims and warranty costs, and 3) deficient tracking ability. The analysis of benefits and the simulation results suggests a potential reduction of costs. A new material flow map and new procedures of certain stages are proposed. Finally, the two pilots are developed as stepping stones to formal implementation of the RFID system in VSEA.

Full textAbstract:
Localization and motion control (navigation) are two major tasks for a successful mobile robot navigation. The motion controller determines the appropriate action for the robot’s actuator based on its current state in an operating environment. A robot recognizes its environment through some sensors and executes physical actions through actuation mechanisms. However, sensory information is noisy and hence actions generated based on this information may be non-deterministic. Therefore, a mobile robot provides actions to its actuators with a certain degree of uncertainty. Moreover, when no prior knowledge of the environment is available, the problem becomes even more difficult, as the robot has to build a map of its surroundings as it moves to determine the position. Skilled navigation of a differential drive mobile robot (DDMR) requires solving these tasks in conjunction, since they are inter-dependent. Having resolved these tasks, mobile robots can be employed in many contexts in indoor and outdoor environments such as delivering payloads in a dynamic environment, building safety, security, building measurement, research, and driving on highways. This dissertation exploits the use of the emerging Radio Frequency IDentification (RFID) technology for the design and implementation of cost-effective and modular control techniques for navigating a mobile robot in an indoor environment. A successful realization of this process has been addressed with three separate navigation modules. The first module is devoted to the development of an indoor navigation system with a customized RFID reader. This navigation system is mainly pioneered by mounting a multiple antenna RFID reader on the robot and placing the RFID tags in three dimensional workspace, where the tags’ orthogonal position on the ground define the desired positions that the robot is supposed to reach. The robot generates control actions based on the information provided by the RFID reader for it to navigate those pre-defined points. On the contrary, the second and third navigation modules employ custom-made RFID tags (instead of the RFID reader) which are attached at different locations in the navigation environment (on the ceiling of an indoor office, or on posts, for instance). The robot’s controller generates appropriate control actions for it’s actuators based on the information provided by the RFID tags in order to reach target positions or to track pre-defined trajectory in the environment. All three navigation modules were shown to have the ability to guide a mobile robot in a highly reverberant environment with variant degrees of accuracy.

Radio Frequency Identification (RFID), for long, has shown potential to replace the current asset identification technologies like barcode readers in the warehouse. However, while the capital costs of implementing RFID technology are well-defined, its benefits in many cases remain intangible and unclear. This thesis seeks to evaluate the technical feasibility of implementing an RFID-based dock door portal for automatic identification and receiving of consumables shipped from Ireland to the Global Distribution Center of Waters Corporation. A systematic procedure is outlined, starting with the assessment of electromagnetic activity at the distribution center to the implementation of a pilot run on a real shipment. Important aspects of RFID system deployment including identification of interrogation zones for the portal, selection of the RFID tag, and its optimal placement on the SKU are studied. Finally, recommendations are made to Waters Corporation based on the performance results of the pilot run.

This thesis implements a 13.56 MHz passive RFID system using the 13.56 MHz Melexis MLX90121 RFID reader transceiver IC and the 13.56 MHz Texas Instruments RI-I02-112A-03 transponder. The major research topics include the ISO 15693 standard, data packet format, communication protocol, baseband coding, and so on. An RFID system comprises a reader and a transponder, which finds numerous applications due to its high data density, fast reading speed, good machine readability, no influence of dirt, and low possibility of unauthorized copying/modification. The 13.56 MHz passive RFID system investigated in this thesis is based on inductive energy coupling and signal transfer between the reader and transponder in the near-field region. Since the 13.56 MHz coil antenna and impedance matching circuit have critical effect on wireless energy transfer and communication range, the design methods for the coil antenna and matching circuit are also discussed in detail. In order to facilitate proper wireless communications between MLX90121 reader transceiver IC and RI-I02-112A-03 transponder, the Microchip PIC16LF877A microcontroller and its 35 PIC16 assembly language instructions are utilized to set the contents of configuration registers of MLX90121. Lastly, the communication reliability and range of the 13.56 MHz passive RFID system implemented are tested in open sites.

Abstract This thesis presents the design and implementation of RFID reader antennas. Using a slot loop with perturbed meander line section, the proposed antenna may successfully achieve the circular polarization requirements, operating at 2.45 GHz. The proposed double-T slot may reduce the antenna area by 30%. Using a reflector ground underneath the antenna, the circularly polarized gain may be raised up to 5~6 dBic. Moreover, a 10% 3-dB axial ratio bandwidth is obtained by using a sequential rotated feed network and 1x2 arrays. The features of the designed antenna include the size reduction, gain improvement, and axial ratio bandwidth enhancement. An electromagnetic simulation and physical explanation is also provided in this thesis to interpret the working principle of circular polarization of the proposed antennas.

Radio Frequency Identification (RFID) is a wireless technology which utilizes radio communication to identify objects with a unique electrical identity. The widespread deployment of RFID technologies may generate new threats to security and user privacy. One of the main drawbacks for RFID technology is the weak authentication systems between reader and tag. In general, weak authentication systems that either leak the password directly over the network or that leak sufficient information while performing authentication to allow intruders to deduce or guess at the password. According to EPCglobal Class1 Gen2 authentication system, the important information in tag will be exposed inadvertently because of the wireless transmission of data while performing authentication and causes much of threat to security. In this dissertation, we study the RFID tag-reader mutual authentication scheme. To avoid direct exposure of vital information from wireless transmission, the primitive exposed information must be covered in authentication process. A hardware implementation of mutual authentication protocol for RFID system is also proposed. The proposed system was simulated using Altera Quartus II software. The system has been successfully implemented in hardware using Altera DE2 board includes an Altera Cyclone II Field Programmable Gate Array (FPGA). The output waveforms from the FPGA have been displayed on the 16702A Logic Analysis System for real time verification. Finally the gate level files have been performed within mutual authentication schemes using Synopsys Design Vision from CIC and analyzed the power dissipation with different authentication schemes by Prime Power.

Radio Frequency Identification is getting more and more popular in the past ten years. RFID reader plays a major role in the RFID system. The power consumption of RFID reader becomes a very important issue. The digital signal processing unit of reader is usually made of variant of microcontrollers. Although, these microcontrollers provide a lot of low power instructions, but reader back to the working mode by interruption caused by user when reader is working at idle mode. We present a low power strategy with gated clock technique by dividing working mode into four modes, configuration mode, active mode, idle mode and user mode and adding an additional mode-controller to handle transitions between each mode. Finally, we design a low power RFID Reader circuit complies with the ISO 14443 TYPE A standard. Experimental results show that the goal of automatic operation is achieved and reduce about 51% of dynamic power consumption in idle mode. Keywords: RFID, Reader, Low Power

Owing to the fast development of manufacturing, communication and embedded system, the miniature electronic device can now concurrently carry out sensing, computing and wireless communication leading to a variety of applications in wireless personal area network (WPAN). The ubiquitous monitoring of personal valuable belongings, such as the delicate consumer electronics (smart phones and tablets), famous-brand wallets/purses, luxurious watches, signed contracts/documents and a variety of keys, is a new type of WPAN application especially for travelers and tourism. To respond this need, a miniature personal-carried monitoring device with salient features of high connectivity, seamless sensing and tracking and lightweight authentication protocol is developed to form a dedicated communication network in the vicinity of personal area. Hence, in this paper, a brand new hardware framework of low-cost, tiny and power-efficient wireless monitoring system is presented. The implementation of personal belongings monitor(PBM) consists of sub-1GHz RFID interrogator subsystem、passive RFID transponder subsystem and antenna. Compare to other interrogators, sub-1GHz interrogator achieves larger communication range and suffers fewer reflections in the indoor space. The sophisticated commercial transponder can be easily embedded in the personal belongings without any battery inside. In addition, a lightweight three-pass authentication process helps to form a simple point-to-point short-range identification network which makes our monitoring system is superior to other monitoring systems using active communication technologies, such as Bluetooth, ZigBee, UWB, Wi-Fi, and so on. In order to enhance sensing distance of PBM, the impedance matching antenna is designed by HFSS and simulates real monitoring scenarios to verify personal identification performance range. Four experimental scenarios have been developed to demonstrate the performance on identification. By connecting and 1.7dBi linear polarized antenna of PBM, under 1 watt power limitation, the proposed PBM has successfully identified all the items within 2-meter range.

The goal in this thesis is to realize a radio frequency identification (RFID) system by the technique of SOPC (system on a programmed chip). As a result of the lack of such a module about receiver and transmitter in the SOPC, we have a reference to the RFID multiple protocol chip TI issues, RI-R6C-0001A, and achieve a self module to simulate the realistic motion which relates to radio signal. It could split RFID signal collision into two groups, tag signal collision and reader signal collision. The former means a reader receives the signal from all the tags respond to, it could make a estimation that exists a error. The latter implies a tag receives so many commands and causes a collision. There are many elements which influence the efficiency of a reader’s recognition, signal collision is not the only reason to cause a wrong information or the bad efficiency. It would clear potential dangers if you learn the correct information about signal collision, and raises the possibility to succeed in achieving the RFID system. The thesis propose a improved anti-collision method based on abs algorithm, it can use less time to recognize all the tags within a reader’s range by way of adding Manchester coding and dividing tactic, and cases a better efficiency.

Radio Frequency Identification (RFID) has been considered as an attractive method for the ubiquitous computing. One area of ubiquitous computing is composed by the location-aware systems, systems where applications are designed to estimate the coordinates of tracking objects in qualified vicinity or in correlation to reference locations. The passive UHF RFID system is an attractive solution for location awareness applications. Passive UHF RFID tags have gained significant popularity due to their low cost, small footprint, ability to function without batteries, faster response rates and longer read ranges as compared to common HF RFID tags. In this thesis, a location-aware systems based on passive UHF RFID technology is proposed. In UHF RFID system, the role of antennas is very important for transfer power and signal. Therefore, reader antenna is a key important component of RFID system. The design and simulation of a patch antenna with circular polarization is presented. A circularly-polarized antenna can help maximize performance of the location awareness system. In contrast to compute the position of the tracking tag based on each individual reference tag, a cluster localization algorithm is introduced to improve the tracking accuracy. Based on the proposed cluster localization algorithm, the performance of the system was within the reasonable accuracy for 3D location estimation. In addition, the FPGA implementation of law of cosines based on CORDIC algorithm is proposed in order to study the feasibility of enhancing the performance of a location awareness system.

RFID technique has gradually been applied to various information system. Early identification technique has evolved from barcode, Magcard, to chip card, and in the near future, will be replaced by RFID technique. At present, RFID reader control most uses RS232, RS485, or USB as the communication interface, So the development of control programs can only be restricted to use stand-alone program to develop the API. In this paper, we will self-develop application programs to read the card number of Mifare card with specifications of ISO 15693, and then store the card number into the remote database. The conference quality will be improved and proceed smoothly when the attendee can freely retrieve the related conference information via the web-based conference information system.

Multi-path fading can easily affect UHF RFID system, and cause signal interference during the communication, which results in instability of link quality and reduction of system performance. This work presents a 925MHz Multi-input Multi-output (MIMO) UHF passive RFID reader to mitigate this problem. In this work, a software defined radio platform manufactured by National Instruments, NI PXIe-5644R, is used to implement the MIMO RFID reader. At the tag end, a MIMO tag that has antenna diversity is used, of which the tag’s antennas are mutually orthogonal-polarized. Hence it’s more reliable in the forward link communication where it exploits selective combing technique to improve the received power. In the reverse link communication, the tag backscatters an encoded signal with space-time block code, and the reader uses two receiving antennas and the maximum ratio combining technique to obtain diversity gain to overcome multi-path fading problem. Additionally, a comparison of system performance between (1, 2, 2) MIMO RFID structure and (1, 2, 1) MIMO RFID structure is also presented.

This paper is mainly divided into three parts. The first part implements a low-sidelobes array antenna, which has multiple directional antennas, and obtains high directionality, but it will generate sidelobes. Therefore, using the Chebyshev polynomial, the array factor is modified to achieve low-sidelobes of array antenna. In the second part, a wideband high-gain Down-Conversion is implemented. The architecture is a modified version of the Gilbert-cell mixer. The mixer is mainly a three-stage cascade architecture. The transconductance stage uses an inverting amplifier with resistance feedback, its transconductance is "g" _"mp" "+" "g" _"mn" . The switch stage is biased in the weak inversion area, so significantly reduce power consumption. The IF output stage uses active resistors to achieve greater output impedance and increase the overall conversion gain of the mixer. In order to increase the bandwidth of the mixer, an active balun was proposed for input impedance matching. However, the P1dB of the active mixer is –25 dB, which is not suitable for RFID systems. Therefore, this design is not used in the third part. The third part, implementing an RFID receiver, uses a direct down-conversion architecture, so there is no need for extra filters, which is beneficial to chip integration. Since RFID is a close-range communication and requires high linearity, it adopts a passive front-end design. The proposed RFID system will receive the PSK modulation signal. In order to enable the receiver to correctly demodulate the PSK signal, the system adopts an orthogonal architecture. The proposed RFID belongs to the UHF operating frequency, the receiver P1dB is –7 dBm, the total power consumption is 12.2 mW, I/Q path gain is 12 dB.

Recently RFID system had been adopted widely in many applications, but the key components are still supplied by the international manufactures. Only a few of local companies have this capability to develop the key components of RFID system. In this thesis, we had accomplished two RFID Systems, which may be applied to access control, parking management and interactive toys. 125kHz RFID system is designed by dual band and dual antenna architecture. The reader contain two antennas, one is for transmitting signal for transponder, and the other one is for receiving respond signal from transponder. Transponder is charged by the reader through the air with 250kHz magnetic signal, then transponder will respond ID code by DPSK modulation at 125kHz. Reader will filter, amplify, and demodulate the signal to analyze the responding code. This design can be operated within the distance of 25 cm. And the 13.56MHz RFID system is especially designed for short range and low cost application, using PWM modulation at 13.56MHz, this design can work within the distance 10 cm. The technology involved in this thesis is very wide including antenna, filter, amplifier, and demodulator circuit for reader and transponder. All system from system spec to circuit design and testing use our own design or co-operate with local IC design companies.

As the rapid development of cloud computing, the cloud-based RFID services become one of the popular research topics in the Internet of things. The services can provide the functions of reader, event, and data management. The services also can handle complex and a large number of tags. However, the reliable and stable RFID services heavily depend on a robust and intelligent RFID middleware for providing correct and real time functions. This thesis proposes a cloud-based intelligent RFID system for providing cloud computing architecture and smart services. It can handle volumes of tags and use grey theory, agent negotiation, and genetic algorithm for providing a load balanced RFID middleware. We use the cloud Ubuntu open source to construct the private cloud RFID warehouse service. The experiment results show that the system can provide a safe, reliable, high performance, and load balanced cloud RFID services.

Multi-path fading degrades performance of an Radio Frequency Identification (RFID) system operating in the Ultra High Frequency (UHF) band. Consequently dual antenna RFID tag with antenna polarization diversity is proposed to mitigate this problem. This work uses a Software Defined Radio platform to implement a corresponding reader for dual antenna RFID tags. In the forward (Reader to tag) link, a dual antenna RFID tag use selective combining technique to improve the performance. In the reverse (Tag to reader) link, the reader uses maximum ratio combining technique to combat multi-path fading. We use Agilent N9010A EXA signal analyzer to measure tag backscatter power at the reader receiver end in a meeting room. We also analyze bit-error-rate to Signal-to-Interference and Noise Ratio (SINR) of the software-defined-radio-based Reader. Experimental results show that the bit-error-rate approaches 2% when SINR is no less than 4 dB. Due to the FPGA gate count limit, the data sampling rate is insufficient; hence the bit-error-rate performance does not increase beyond 4dB.

In recent years, radio frequency identification (RFID) has become an important infrastructure technology. It is a fast, secure, and efficient identification procedure that influences many various applications, such as supply chain management, toll-payment, libraries, e-passports, and shopping. RFID technology works in a wireless environment in which a reader has to identify many tags at the same time. This usually leads to collisions and unidentified data in reading process. Therefore, one always strives to solve such an anti-collision problem. However, most research effort is usually limited to the stage of system simulation. Although the simulation is actually performed in accordance with the protocol, it is still not enough to explain the reliability in the real work. This research builds a RFID platform, including work of anti-collision algorithm, programs of compilation and burning, method of data collecting, and so on. We select a well-known algorithm (Schoute’s Method) to implement and compare with a base line algorithm (low bound method). The experiment results are quit consistent with that from other works of research. Thus, the experiment platform we built is reliable in actual work. Future research can focus on more efficient anti-collision algorithms, and use this experiment platform to verify the algorithms.

Inventory management is an important issue in many businesses. The purpose of inventory management is to make it possible to control and dispatch inventory efficiently. Barcode is used frequently for inventory management, but the disadvantages of barcode are too many. According to the result, RFID (Radio Frequency Identification) has been become an important technique recently. The price of tag of RFID is too expensive to popularize. Apply RFID to inventory management will make a lot of benefits and will become the best tool for inventory control. The research bases on warehousing management system and focuses on each level of product control. The purpose of applying RFID to control product entry permit is to reduce the times and to make permit efficiently.

Radio Frequency Identification（RFID）now is a popular technology, and it has been widely deployed in many daily applications like access control, inventory control, MRT ticket, supply chain management, etc. Once we take the advantages of RFID technology, keep researching and innovating as well as plan and establish completely, then we can enhance operating efficiency and reduce the labor cost, and also provide high-efficiency platforms for related industries and living standard. This thesis focuses on designing and implementing secure RFID campus applications. We choose Mifare standard card because it provides multi-sectors and each sector has its own access keys. It facilitates designers to design multi-applications on one card. In this study, we design an e-cash system which covers the applications in seven-eleven convenient store, restaurant and ticket selling service. Through prototyping, we hope to build up a reference model for future campus deployment.
