We present a path determination method for an unmanned aerial vehicle (UAV) equipped with a radio frequency identification (RFID) interrogation system. UAV path design is one of the main factors influencing the cost of UAV inventory management systems. A case study for using a path-optimized UAV-RFID system is presented. In this case study the RFID-UAV travels above the pastures of an extensive cattle ranch scanning the RFID tags attached to the cattle in order to detect their locations. Since the UAV battery limits the flight time, the UAV path must be segmented and landing locations for recharging or battery replacement must be determined. Scanning a cattle RFID tag requires the UAV to fly within a certain distance from the animal, as opposed to approaching the animal’s exact location. The reading distance (RD) of the RFID equipment determines the allowable distance. We use an easy-to-explain method to determine the UAV path. We generate a RD-based hexagonal tiling of the pasture and minimize the UAV path such that it visits all the tile center points. Based on the current UAV system configuration and environmental conditions, the optimal UAV tour allows for the scan of each pasture segment’s animals to be completed within the battery-limited flight time. A case study was performed at the California Polytechnic (Cal Poly) State University’s Escuela and Walters Ranches. The RFID-UAV system solution is estimated to be 62%faster than the current cattle scanning practice, which requires ranch employees to search for and scan each animal from close proximity.

Electronic healthcare or E-Health promises to offer better care at lower cost. This is critical as the cost of healthcare continues to increase and as the population ages. Radio Frequency Identification (RFID) technology is one form of wireless technology that will be part of the E-Health environment. RFID provides the ability to identify, track, and monitor patients and staff members. This enables better resource allocation, reduction of medical errors, and increased independence for patients. One part of E-Health is the Electronic Medical Record (EMR). New developments in RFID technology now enable the storage of all or part of the EMR on an RFID tag that remains with the patient. This chapter investigates the use of RFID in E-Health, how RFID can be used to store the EMR, and the security and privacy risks associated with using RFID to store the EMR.

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.

The electromagnetic (EM) imaging technique at mm-band 60 GHz is proposed for data encoding purpose in the chipless Radio Frequency Identification (RFID) systems. The fully printable chipless RFID tag comprises tiny conductive EM polarizers to create high cross-polar radar cross-section. Synthetic aperture radar approach is applied for formation of the tag's EM-image and revealing the tag's content. The achieved high data encoding capacity of 2 bits/cm2in this technique based on a fully printable tag is very convincing for many applications. The system immunity to multipath interference, bending effect, and printing inaccuracy suggests huge potentials for low-cost item tagging. Tags are also readable through a tick paper envelop; hence secure identification is provided by the proposed technique.

Abstract This paper presents a polarization-independent 11-bit chipless RFID tag based on frequency-selective surface which has been designed for encoding and relative humidity (RH) sensing applications. The 10 exterior U-shaped resonators are used for item encoding whereas Kapton has been incorporated with the interior resonator for RH sensing. This radio-frequency identification (RFID) tag operates in S- and C-frequency bands. The proposed design offers enhanced fractional bandwidth up to 88% with the density of 4.46 bits/cm2. Both single- and dual-layer tags have been investigated. The simulated results are in good agreement with measured results and a comparison with existing literature is presented to show the performance. Simple geometry, high code density, large frequency signature bandwidth, high magnitude bit, high radar cross-section, and angular stability for more than 75° are the unique outcomes of the proposed design. In addition, RH sensing has been achieved by integrating the Kapton on the same RFID tag.

This overview discusses how precision sheep management could be utilised in the Australian sheep industry to improve production efficiency and reduce animal welfare concerns due to low monitoring frequency by stockpeople. The concept of precision sheep management is described. This is a system in which sheep are managed as individuals or small groups rather than as a (whole) flock. Precision sheep management utilises the application of radio frequency identification technology, enabling producers to better monitor sheep in extensive situations, and contribute to improved efficiency of management and sheep welfare. Examples of combining radio frequency identification with other technologies such as walk-over-weighing and Pedigree Matchmaker are discussed. These technologies provide producers with tools to improve the cost effectiveness of, and labour efficiency associated with, collecting data on individual animals. The combined technologies should also improve consistency and reliability of information, enhancing decision-making by producers, for example, from regular monitoring of biometric variables such as liveweight, or calculating breeding values to enable superior genetic comparisons over time.

With the development of the Internet of Things and Radio Frequency Identification (RFID), indoor positioning technology as an important part of positioning technology, has been attracting much attention in recent years. In order to solve the problems of low precision, high cost and signal collision between readers, a new indoor positioning algorithm based on a single RFID reader combined with a Double-order Gated Recurrent Unit (GRU) are proposed in this paper. Firstly, the reader is moved along the specified direction to collect the sequential tag data. Then, the tag’s coordinate is taken as the target value to train models and compare them with existing algorithms. Finally, the best Gated Recurrent Unit positioning model is used to estimate the position of the tags. Experiment results show that the proposed algorithm can effectively improve positioning accuracy, reduce the number of readers, cut down the cost and eliminate the collisions of reader signals.

A realização de um inventário não é uma tarefa fácil, principalmente em universidades federais, que possuem muitos bens permanentes. A gestão patrimonial é realizada através de procedimentos de identificação, tombamento, localização, contagem, preservação e desfazimento de bens. Devido a grande quantidade de informações e necessidade de segurança, confiabilidade e celeridade nos processos, deve-se buscar alternativas para melhorar a gestão, reduzir índices de não conformidades e aprimorar o planejamento de compras. O sistema RFID (Radio-Frequency Identification), por exemplo, funciona por meio da comunicação via radiofrequência, com uso de um chip passivo inserido em etiqueta inteligente. Dessa forma, o objetivo deste artigo é analisar a viabilidade do uso da tecnologia RFID para o aperfeiçoamento da gestão patrimonial na Universidade Federal do Vale do São Francisco - Univasf por meio do levantamento de suas vantagens, desvantagens e custos para implantação. Para isto, são realizadas pesquisas em periódicos e bases de patentes, além da realização de entrevistas e análise documental. Entre os principais resultados, constata-se que o processo de gerenciamento de bens da Univasf é realizado de forma manual e desgastante para servidores membros de comissão, para a qual são convocados sem consulta prévia, verificando-se ainda que os prazos são, comumente, ultrapassados. Por outro lado, o custo para implantação do sistema RFID para controle do número atual de bens da Univasf corresponde a apenas 0,78% do valor alocado para as ações orçamentárias referentes às despesas correntes e investimentos, constituindo fatores favoráveis a sua aquisição pela Instituição.Palavras-chave: Radiofrequência.

Internet das coisas. Smart tags in the public administration: feasibility analysis in thepatrimonial control of the UNIVASFAbstractThe construction of an inventory is not an easy task, especially at federal universities, which have many permanent assets. The patrimonial management is carried through procedures of identification, tipping, localization, counting, preservation and undoing of assets. Due to the large amount of information and the need for security, reliability and speed in the processes, alternatives should be sought to improve management, reduce nonconformity rates, and improve procurement planning. The RFID (Radio Frequency Identification) system, for example, works by means of radio frequency communication, using a passive chip inserted in a smart tag. Thus, the objective of this paper is to analyze the feasibility of using RFID technology to improve asset management at the Federal University of Vale do São Francisco -Univasf by surveying its advantages, disadvantages and costs for implementation. For this, research is carried out in journals and patent bases, as well as interviews and document analysis. Among the main results, it can be seen that Univasf's asset management process is carried out manually and exhausting for commission member servers, to which they are summoned without prior consultation, and it is also verified that the deadlines are commonly outdated. On the other hand, the cost of implementing the RFID system to control Univasf's current number of assets corresponds to only 0.78% of the amount allocated to budget actions related to current expenses and investments, constituting favorable factors for their acquisition by the Institution.Keywords: Radiofrequency.

Radio Frequency Identification (RFID) is promising, as a technique, to enable tracking of essential information about objects as they pass through supply chains. Information thus tracked can be utilised to efficiently operate the supply chain. Effective management of the supply chain translates to huge competitive advantage for the firms involved. Among several issues that impede seamless integration of RFID tags in a supply chain, one of the problems encountered while reading RFID tags is that of collision, which occurs when multiple tags transmit data to the same receiver slot. Data loss due to collision necessitates re-transmission of lost data. We consider this problem when Framed Slotted ALOHA protocol is used. Using machine learning, we adaptively configure the number of slots per frame to reduce the number of collisions while improving throughput.
