Resumen

Abstract There has been growing interest in the use of passive harmonic RFIDs for diverse range of applications. Conventional RFIDs are prone to self-jamming and multipath interference, and these challenges can be mitigated using the harmonic RFID design. Recently several harmonic RFID designs have been demonstrated. However, there are many designs related, packaging and intellectual property challenges associated with new tag designs. It has been well known that conventional RFIDs produce harmonic content, which is typically suppressed to reduce background noise. Previous experiments have demonstrated that the harmonics generated by conventional RFIDs can be utilized to enhance their performance. In this paper, an RFID chip is characterized for the generation of harmonic frequencies. This is carried out by designing a high frequency board that contains calibration structures along with structures to characterize the RFID chip using a one port network. An equivalent model is then developed, which in turn is used to design a dual band antenna that works at the fundamental and harmonic frequencies. In addition, the conventional RFID interrogator is modified to accommodate the measurement of harmonics generated by the RFIDs. A complete harmonic tag system is designed and implemented, and an example application of harmonic RFID is demonstrated. Here, the harmonic RFID tag is used in an industrial setting where there is large clutter (large reflections from metal structures).

Resumen

This paper examines attitudes towards Radio Frequency Identification (RFID) technology and explores the wider concerns of the ever increasing prospect of social tagging. Capturing vignettes and narratives from a sample of study participants, the paper highlights concerns about adopting RFID implements now and in the future. The views captured through qualitative methodology act as the platform for a wider argument concerning the human rights and privacy intrusion concerns over IT applications. Intended as an insight into the reality of technology impact, this paper lists a series of questions for leaders to consider over matters of human rights specifically concerning RFID adoption. The authors conclude that caution, naivety and fear are the underlying reasons for society accepting RFIDs without question and that RFIDs will be a part of everyday working and domestic life in the near future.

Resumen

The world’s oil and gas is transported using a network of steel pipelines most of which lie underground. The length of this network in the US/Canada alone is 3.5 million kilometers. Keeping track of pipes in such a network for pipeline-health monitoring, maintenance, and logistics is an acute problem faced by pipeline-operators. Recently, radio-frequency-identification tags (RFIDs) have been proposed for tracking pipelines and even for monitoring pipeline health with additional built-in sensors. Low-cost RFID tags are wirelessly powered and battery-less. However, RFIDs do not function optimally in the presence of magnetic carbon steel pipes that are prevalent in the industry. High-frequency wireless signals also attenuate rapidly through wet soils. In this research, the use of passive RFID sensor platforms for interrogating buried pipes up to 1.25 m deep in the LF bands is proposed. Using magnetic-induction-based communication, a test-comparison between conventional full/half duplex (FDX/HDX) and sequential (SEQ) RFID schemes is detailed. Wireless measurements in the presence of an industry-standard ASTM A-53 carbon-steel pipe show a SEQ RFID offering better immunity against magnetic proximity effects of the pipe’s wall with an 8.3 dB (x6.8) improvement over a FDX/HDX RFID operating under similar conditions over a distance of 80–125 cm at which pipes are typically buried.

Resumen

There will be increasing demand for high confidentiality, integrity, authentication, for widely deployment of the next RFID generation beside that, the focus will be on avoiding encryption algorithms; as these require more complex modulation, to secure communication between RFID’s tags and readers. In this paper, the focus will be on securing the communication channel between tags and readers at the physical layer, rather than to secure the contents of RFIDs data by encryption. The RFID reader initially will communicate with the tag through a narrowband communication and subsequently through broadband communication, by generating ultra wide-band signal using pulse position modulation with time hopped, it can be a novel approach for RFID security as it simplify or eliminate cryptographic requirements with the same security level of existing passive RFIDs, also it allow simultaneous multiple access without-collision, which will enhance the overall RFID systems performance. The design of the system will be shown by modeling the communication, the designing details of the transmitter as well as the receiver, finally showing the simulated results of modulated signal with its specific parameters as well as the receiver performance.

Resumen

The purpose of this study is to describe a methodology to assess the financial viability of radio frequency identification (RFID) applications and the main contributions of this technology. The impact of RFID technology on supply chain processes was assessed using an Internal Rate of Return analysis. An extensive, six-month discussion and refinement process with the logistics and supply chain managers of the company under study was conducted to validate the procedure and to collect the necessary data. Such technology enables inventory control, tracking of parts/products and customer satisfaction. The viability of using RFID technology for inventory control and product tracking was confirmed. Among the benefits obtained: the reduction of one worker from the inventory team, reduction in the costs for replacing a component and reduction in the costs incurred with defective components were found. This is one of the few attempts to quantify RFDI technology’s contribution.Keywords: Economic Engineering. RFID. Radio Frequency Identification. Financial Viability Analysis. Internal Rate Of Return.

Resumen

Abstract: Increased protection of resource-constrained devices, such as radio frequency identification (RFID) systems, is in high demand these days. For high-resource desktop PCs, current encryption techniques are sufficient. Access control systems, transaction banking systems, and payment systems are all examples of high-security applications where RFID technology are used. The attacker tries to deceive RFIDs in order to gain illegal access to services without paying for them or to get around security measures by detecting a secret password. The most difficult problem with RFID systems is ensuring effective protection against such infringements. For RFID systems, lightweight cryptography can give security assurance. SLIM is a novel ultralightweight cryptography technique for RFID devices presented in this paper. Since block ciphers are the most commonly used cryptographic and provide highly strong protection for IoT devices, SLIM is a 32-bit block cipher based on the Feistel structure. The most difficult aspect of creating a lightweight block cipher is balancing performance, cost, and security. SLIM, like all symmetric block ciphers, encrypts and decrypts using the same key. The suggested method performs well in both hardware and software contexts, has a small implementation footprint, a reasonable cost/security ratio for RFID devices, and is energyefficient. SLIM has shown high immunity to the most successful linear and differential cryptanalysis assaults, as well as a substantial margin of defense against them.

Resumen

The ubiquity of illumination facilities enables the versatile development of Visible Light Communication (VLC). VLC-based research achieved high-speed wireless access and decimeter-level indoor localization with complex equipment. However, it is still unclear whether the VLC is applicable for widely-used battery-free Internet-of-Things nodes, e.g., passive RFIDs. This paper proposes LightSign, the first cross-technology system that enables passive RFID tags to receive visible light messages. LightSign is compatible with commercial protocols, transparent to routine RFID communications, and invisible to human eyes. We propose a pseudo-timing instruction to achieve microsecond-level light switching to modulate the VLC message. To make it perceptible to passive RFIDs, we design an augmented RFID tag and prove its effectiveness theoretically and experimentally. With only one reply from an augmented tag, LightSign can decode 100-bit-long VLC messages. We evaluate LightSign in real industry environments and test its performance with two use cases. The results show that LightSign achieves up to 99.2% decoding accuracy in varying scenarios.

Resumen

Residual feed intake (RFI) gained attention as a potential alternative to the feed conversion ratio (FCR). Thus, this study aimed to estimate genetic parameters for different feed efficiency (FE) traits (FCR, RFI1 to RFI5) and their genetic correlation to on-test daily weight gain (ADG), backfat (BFT), loin muscle area (LMA), lean percentage (LP), and total feed intake (FI) for 603 Male Duroc (DD), 295 Landrace (LL), and 341 Yorkshire (YY). The common spatial pen effect was also estimated in these traits. Five RFI measures were estimated by regressing daily feed intake on initial testing age (ITA), initial testing weight (IBW), and ADG for RFI1; other models were the same as RFI1 except for additional BFT for RFI2; LMA for RFI3; BFT and LMA for RFI4; BFT, LMA, and average metabolic body weight (AMBW) instead of IBW for RFI5. Genetic parameters estimated using two animal models and the REML method showed moderate heritability for FCR in all breeds (0.22 and 0.28 for DD, 0.31 and 0.39 for LL, 0.17 and 0.22 for YY), low heritability for the majority of RFI measures in DD (0.15 to 0.23) and YY (0.14 to 0.20) and moderate heritability for all RFI measures in LL (0.31 to 0.34). Pen variance explained 7% to 22% for FE and 0% to 9% for production traits’ phenotypic variance. The genetic correlation revealed that selection against less complex RFI1 in DD and LL and RFI2 in YY would bring the most advantageous reduction to FI (0.71 for DD, 0.49 for LL, 0.43 YY) without affecting ADG in all breeds (0.06 for DD, −0.11 for LL, 0.05 for YY), decrease in BFT, and increase in LP in DD (0.51 in BFT, −0.77 in LP) and LL (0.45 in BFT, −0.83 in LP). Therefore, inclusion of these breed-specific RFI measures in the future selection criteria would help improve feed efficiency in the swine industry.

Resumen

In many industrial sectors, the use of RFID in closed systems is evolving. To be implemented in global supply chains, all aspects related to RFID need to be standardised. By collecting, processing and distributing information efficiently, organisations should be able to improve the efficiency of their transport logistics processes, lower their operational costs, and improve their portfolio of logistics services. This case study describes the current perspectives, challenges and benefits of RFID applications in manufacturing industry. Automated, remote and wireless identification is a basic element in implementing efficient management systems in the supply chain. The most important identification techniques are barcode and RFID. Barcode is currently the most widely used method for the identification of parcels, but RFID is more suitable for automated identification for many different reasons including better readability and enhanced environmental durability. By reducing manual work and errors, RFID generates cost savings, increased productivity and efficiency of processes. There is a wide range of different RFID technologies that have varying reading ranges, protocols and data contents. There are two different approaches to using RFID tags and numbering the items to be identified. Recent standardisation developments have started to resolve the interoperability problems in the field of RFID identification.

Resumen

Teknologi berkembang sangat pesat beberapa tahun terakhir terutama pada teknologi berbasis Radio Frequency Identification Device (RFID). Hal ini disebabkan oleh banyaknya kebutuhan yang menggunakan teknologi. Pemanfaatan sistem RFID di Indonesia sebagian besar masih menggunakan perangkat keras RFID seperti transponder RFID dan RFID reader module yang dibeli dari negara lain seperti Cina atau negeri lainnya. Industri di Indonesia yang menggunakan RFID juga rata-rata masih membeli dan tidak memproduksi sendiri. Dari masalah yang ada, maka adanya peluang untuk memproduksi perangkat RFID ini baik transponder RFID maupun modul pembaca transponder RFID yang mirip dengan RFID yang sudah ada. Dalam penelitian ini dilakukan pembuatan modul pembaca transponder RFID dengan tahapan yang dimulai dari membuat skematik rangkaian modul pembaca transponder RFID, membuat layout PCB, mencetak PCB sesuai desain PCB, melakukan assembly komponen dengan menggunakan solder manual, dan melakukan pengujian. Hasil pengujian fungsi menunjukkan bahwa modul pembaca transponder RFID yang dibuat hanya bisa membaca kartu RFID dengan jarak tapping maksimal pada jarak 7 mm, sedangkan modul pembaca transponder RFID yang di pasaran bisa membaca kartu RFID dengan jarak tapping bisa lebih dari 7 mm.

Resumen

The aim of this post is to point out the use of RFID robots in the management of logistics processes. RFID technology is defined first. RFID technology represents identification using radio frequency waves. The principle is to store the necessary data in radio frequency memory chips and then repeatedly read or write the data using a reader. We divide RFID chips into active and passive. Active RFID chips use energy from a battery, while passive RFID chips are a technology without an internal power source. Passive RFID is the most common form of RFID in warehouses, using which inventory is taken using RFID robots or hand-held RFID readers. Nowadays, many RFID robots from different manufacturers are available on the market. When choosing, I must consider where we want to use the RFID robot and choose the one that suits us based on its specific characteristics. The RFID robot is a mobile and autonomous RFID system that performs an inventory of the given space based on our initial setup. The RFID robot locates each item in 2 dimensions (x and y). Most robots can move in all directions because they can rotate without shifting. The accuracy of the inventory using the RFID robot ranges from 95-99%, while the accuracy of the inventory performed by employees using handheld RFID readers ranges from 85-95%. As for speed, it is on average 10 times faster compared to manual RFID readers.

Resumen

Future technologies and applications for the Internet of Things (IoT) will evolve the process of the food supply chain and create added value of business. Radio frequency identifications (RFIDs) and wireless sensor networks (WSNs) have been considered as the key technological enablers. Intelligent tags, powered by autonomous energy, are attached on objects, networked by short-range wireless links, allowing the physical parameters such as temperatures and humidities as well as the location information to seamlessly integrate with the enterprise information system over the Internet. In this paper, challenges, considerations and design examples are reviewed from system, implementation and application perspectives, particularly with focus on intelligent packaging and logistics for the fresh food tracking and monitoring service. An IoT platform with a two-layer network architecture is introduced consisting of an asymmetric tag–reader link (RFID layer) and an ad-hoc link between readers (WSN layer), which are further connected to the Internet via cellular or Wi-Fi. Then, we provide insights into the enabling technology of RFID with sensing capabilities. Passive, semi-passive and active RFID solutions are discussed. In particular, we describe ultra-wideband radio RFID which has been considered as one of the most promising techniques for ultra-low-power and low-cost wireless sensing. Finally, an example is provided in the form of an application in fresh food tracking services and corresponding field testing results.

Resumen

Many technologies, such as Radio Frequency Identification (RFID), have been developed to keep pace with rapid changes in society. Additionally, an RFID tag can be integrated with a sensor or actuator (a smart RFID), they can comprise a sensitive wireless network. The potential and utility of smart RFID techniques have increased dramatically. However, based on the distinctive characteristics of RFID and sensors/actuators, they cannot be combined simultaneously using commercial RFID techniques and materials such as poly phenylene sulfide (PPS). Conversely, smart RFID systems will be exposed to harsh environments, including temperature variations, salt corrosion, and violent impact. The current polymeric RFID packaging technique cannot withstand severe environmental conditions for a long period. This study presents a novel integrated packaging technique for sensors and RFID that is fully compatible with the complementary metal-oxide-semiconductor (CMOS) processes to identify the limitations of traditional RFID packaging methods. After several tests in harsh environments, such as strength, corrosion resistance, thermal stress, and simulated washing, the RFID and sensor operated normally. Therefore, the novel encapsulation process for RFID integrated with a sensor overcomes the bottleneck of conventional RFID packaging techniques. The potential of this novel technique is significant and provides a new approach as it achieves high performance and at a low cost. Furthermore, the proposed new technique should prove very useful in applications as smart RFID areas.

Resumen

Last two decades encountered various technological innovations. RFID is one of these changes. RFID impacted and eased out the day to day life of merchandisers and customers as well. RFID replaced the paper bases system of keeping the records. RFID has proved its importance in various classifications of science society and technology. RFID is a technology that uses radio waves to exchange data between devices. The three main components of an RFID system are readers, tags, and a back-end. The initial objective of RFID was identication of objects. Early applications of RFID systems include tracking systems for farm animals, library items, and airport baggage. Over the years, RFID tags have become more powerful and are used in applications that require more than mere identification.

Resumen

Keamanan pada server data diperlukan untuk mengamankan semua data yang dimiliki oleh suatu instansi. Pengembangan akses keamanan ke ruang server juga perlu ditingkatkan untuk melindungi semua data yang dimiliki oleh instansi tersebut.

Resumen

RFID concepts have been evolving for more than fifty years, nevertheless it was until the last decade that this technology settled as one of the leading commercial solutions being applied on, for example tracking, access management and document registration applications, among others. This technology has brought many benefits to the users, like automation processes, inventory time reduction and information transmission reliability. However, before commercializing the RFIDs, test and characterization procedures must be executed in order to provide the correct information to the user. Unfortunately, lack of characterization methodology standards, high cost and high-complexity test equipment are recurrently dis-advantages. This work presents an RFID characterization methodology that uses a low-cost and handy RF signal platform for Electronic Product Code (EPC) time extraction.

Resumen

Radio frequency identification (RFID) is a new material identification technology. RFID has a greater number of benefits than its predecessor, the bar code. It is not universally adopted in many industries due to its high cost hitherto. Whereas, RFID is advantageous because it does not require line-of-sight scanning, it acts to reduce labor levels, enhances visibility, and improves inventory management. This article briefly introduced component, principle and characteristic of the RFID technology, and analyzed and introduced more foregroundful application of RFID in modern logistics. RFID technology is combined with network technical and database technology, it will be extensively applied in stock tache, storage tache, transportation tache, retail tache of logistics system. In addition, this paper also discussed the factors which restrain RFID technology from being broadly applied. The uppermost problem faced by RFID technology is the cost of RFID chip, then it comes to the potential intervention of people’s privacy incurred by the use of RFID technology. Otherwise, lack of uniform criteria definitely affects the development of RFID technology.

Resumen

Fast and reliable identification of Radio Frequency Indentification (RFID) tags by means of anticollision (MAC) protocols has been a problem of substantial interest for more than a decade. However, improvements in identification rate have been slow, as most solutions rely on sequential approaches that try to avoid collisions, which have limited margin for performance improvement. Recently, there has been growing interest in concurrent techniques that exploit the structure of collisions to recover tag IDs. While these techniques promise substantial improvements in speed, a key question that remains unaddressed is how to deal with noise or interference that might introduce errors in the recovery process at the reader. Our goal in this paper is to consider a noisy wireless channel and add robustness to concurrent RFID identification techniques. We propose a new protocol, called CIRF (Concurrent Identification of RFids), which uses multiple antennas to add robustness to noise and leverages block sparsity-based optimization to recover EPC IDs of transmitting tags. We include fail-safe methods to handle errors that persist after the optimization stage. Extensive simulations show that CIRF achieves substantial resilience improvement in a range of very low to medium Signal-to-Noise (SNR) situations, being able to always correctly recover 99% of tags.

Resumen

Radio frequency identification (RFID) is a growing technology for monitoring and recognizing objects, persons, or animals via wireless communications. Precisely, RFID can operate longer range and has an ability to be automated without human control. Chipless RFID tag basically is a RFID tag that does not require a microchip in the transponder. The major impediments in designing chipless RFID tag are data encoding and transmission. The passive chipless RFID tag can be fabricated on any substrate material without external operating circuit, which is different compared to a conventional chipped RFID tag. In this paper, 20 resonators are used to design a 20-bit chipless RFID tag, which operates at the ultra-wideband (UWB) frequency range between 3.00 and 10.00 GHz. It is found that the additional resonators can encode data and increase the chipless RFID tag's encoding capacity significantly. In sum, multiple resonators enable the chipless RFID tag to encode data at different operating frequencies.

Resumen

Radio Frequency Identification (RFID) is a highly beneficial technological advancement which could eventually change the way of doing business. However, the difficulty in assessing the potential benefits of RFID has been delayed RFID related investment decisions within organizations. Especially, time lag, or payback time from RFID investment, has been one of key barriers in RFID investment. This study provides a conceptual framework for time lags in RFID to enhance the understanding of RFID pay-offs. Time lags are determined by IT type and a firm’s IT capability. Therefore, it takes longer for firms to realize the value of RFID since it requires more efforts and changes to implement and utilize. Also the expected time lags of RFID may be modified by the level of IT capability of each firm. The stronger IT capability the firm has, the shorter time lags the firm experiences.

Resumen

Ten years have passed since Wal-Marts public announcement about its RFID technology adoption plan in 2003. Some large competitors of Wal-Mart in the U.S. retail industry jumped on the trend of RFID technology adoption. However, there has been a slowdown of RFID technology adoption since 2008. Many U.S. retailers do not consider adopting RFID technology because of the uncertainty of return on investment and the lack of business cases demonstrating its profitability or efficiency. This study investigates whether RFID companies have better financial performance ratios in the U.S. retail supply chains. RFID retailers have significantly lower days-in-inventory and lower per-employee costs. Compared with pre-RFID, the RFID retailers do not improve profit ratios after they adopted it, but their days-in-inventory ratio and sales efficiency improve significantly. Panel data regression analyses show that inventory management efficiency does impact gross margins, but the impact of cost efficiency is negligible. RFID retailers have a positive relationship with gross margin increases. In summary, it could be stated that introducing RFID improves inventory management efficiency but we do not know yet if RFID technology adoption also contributes to profitability in U.S. retail industry.

Resumen

Abstract. The sensitivity of passive UHF RFID transponders (Radio Frequency Identification) is the key issue, which determines the maximum read range of an UHF RFID system. During this work the ability of improving the sensitivity using solar energy harvesting, especially for low light conditions, is shown. To use the additional energy harvested from the examined silicon and organic solar cells, the passive RFID system is changed into a semi-active one. This needs no changes on the reader hardware itself, only the used RFIC (Radio Frequency Integrated Circuit) of the transponder has to possess an additional input pin for an external supply voltage. The silicon and organic cells are evaluated and compared to each other regarding their low light performance. The different cells are examined in a shielded box, which is protected from the environmental lighting. Additionally, a demonstrator is shown, which makes the measurement of the extended read range with respect to the lighting conditions possible. If the cells are completely darkened, the sensitivity gain is ascertained using high capacity super caps. Due to the measurements an enhancement in range up to 70 % could be guaranteed even under low light conditions.
