摘要： Purpose The purpose of this study is to explore the factors that affect the adoption of radio frequency identification (RFID) technology in Saudi Arabia's logistics services industry. The specific focus is the influence of key variables in multiple domains: technology (complexity and compatibility);organization (top management support, firm size, quality of human capital and integration of supply chain strategy);and environment (information intensity, competitive pressure, trading partner pressure and regulatory pressure). Design/methodology/approach Data were obtained by distributing a survey instrument to a target sample of 459 Saudi logistics company employees whose positions meant they were well placed to explain the operations and technologies used in their organizations. In total, 459 useable responses were received, which also constituted the final sample for the analysis. The survey was validated using confirmatory factor analysis, and the study hypothesis was tested using binary logistic regression. Findings Of the firms represented in the data collected, 70% had not adopted RFID technology. Cost issues, technical issues and lack of industry standards were identified as the main factors hindering the decision to adopt RFID. The results of the binary logistic regression show that top management support, quality of human capital, firm size and trading partner pressure are the variables that most influence whether or not a firm adopts RFID technology. Practical implications According to the analysis, it is imperative that the industry adopt RFID given that this technology can provide strategic and operational advantages. Based on the findings, small and medium enterprises in the logistics services industry require governmental support in terms of providing funding, training and a supportive regulatory environment. Support of this nature would encourage logistics services companies to adopt new technology and move toward applying the global standards developed

摘要： Antenna design is crucial for the continuous development of RFID systems as antennas are indispensable and influence system performance. The need for efficient antennas while being small and lightweight has attracted engineers and researchers for the study and development of it. RFID antenna design is more sophisticated art as compared to the conventional ones. Generally, tag antenna will be small, mobile, passive and linearly polarised while reader antennas are fixed, bulk and are circularly polarized. As such, many proposals were made by the scientific community to try and alleviate the issue using different types of antennas, feeds, and substrates and their combinations. However, the wide range of solutions and their diversity make it hard to have a clear and fair overview of the different works. This paper surveys the most relevant and recent known state-of-the-art antenna design for RFID applications. Along with basic rules, clues and guidelines about efficient antenna design;we show an example of dual-band circularly polarized reader antenna developed in our lab for practical applications. © , CC BY.

摘要： Continuous advances of Information Technologies (ITs), and in particular of the RFID technologies that allow the connection between the physical world objects and the IT infrastructure, have guaranteed the improvement and efficiency of industrial technologies in the last decades. This paper includes the proposal of two new schemes for RFID. On the one hand, it describes the internals of a lightweight Pseudo-Random Number Generator (PRNG) suitable for low resource devices such as passive RFID complying with the EPC Gen2 specifications. On the other hand, a new secure mutual authentication protocol for such RFID devices that uses the proposed PRNG is presented. The design of the proposed PRNG is based on a nonlinear filter of a Linear Feedback Shift Register (LFSR), and the authentication protocol is lightweight. Both schemes fulfill all practical requirements of low-cost RFID such as resource limitation of EPC Gen2 tags. This is thanks to that only simple computation modules such as the proposed LFSR-based pseudorandom generator and bitwise operations are required. The combination of both proposals guarantees at the same time low power consumption and secure features such as authentication, confidentiality and anonymity. © 2022, CC BY-NC-ND.

摘要： The next big revolution after internet in the global information industry is Internet of Things. RFID technology which is short for Radio Frequency IDentification, plays a crucial role in IoT proliferation. The unique characteristic of RFID as an identification sensor (connecting non-computing things to internet) is the major driving force behind the huge popularity of IoT. While there has been considerable progress in adopting RFID, a strong understanding of the fundamentals required for innovation is missing. To draw advantage from the wide-spread acceptance of RFID technology, it will become important to have a complete review of all its components. This article analyses the literature from World War II to the present and is, as far as our knowledge goes the first survey focusing on RFID system for enabling IoT. Other surveys do exist that, rather than analyzing the technology being designed to enable IoT with sensing and actuating devices focus on security and privacy issues, or on the other end discuss the applications of RFID systems. In this survey, we make an exhaustive review of RFID technology working towards connecting all the physical devices to the internet. We commence the discussion with a historical perspective, evolution, RFID frequencies and subsequently, we make an in-depth survey of underlying components encompassing tags, readers and middleware. For alleviating the increased perception of threats, we make a detailed review of security and privacy issues and present the preliminary outcomes of extensive research carried to mitigate them. Short tutorial descriptions are provided as and when the demand arose. Compared to other survey papers in this field, our objective is to provide a more thorough summary of RFID fundamentals to enable researchers and application developers to get upto speed quickly on how the different components fit together to deliver desired functionalities in IoT without having to go through complex details of RFID systems (R

摘要： Monitoring of atmospheric pollutants is a key point for preventive conservation since these species are known to impact the integrity of many artifacts including metals, papers, pigment and textiles. The problem can be amplified in closed environments, like in exhibition rooms and showcases, where temperature and relative humidity gradients and levels can introduce additional micro-climatic problems. One objective of the EU-SensMat project concerns the development of low cost and low visual nuisance sensors sensitive to these pollutants, making them affordable for all museums including small ones. For this purpose, the Radio-Frequency Identification (RFID) technology was considered to produce air-quality sensors based on reactive metallic dosimeter. Besides the low cost, they can be easily integrated to other existing RFID applications such as identification tasks since the interrogation is made with a commercial UHF-RFID reader. The description and the main features of these sensors are discussed in this paper. Moreover, as it will be shown, the subsequent chemical analysis of the sensitive part of the sensors provide useful information to determine the origin of the pollutants.
