“…When a RFID tag enters the changing magnetic field generated by the antenna coil of the reader, an induced voltage is generated in the coil of the tag, which enables the tag to obtain operating energy [12]. Faraday's law of electromagnetic induction states that the induced voltage is proportional to the rate of change of the magnetic flux through the coil [13] and is related to the following factors:…”

As times change and technology advances, people are increasingly enjoying the convenience brought by modern technology, and the library industry is no exception. Now more and more libraries have begun to adopt RFID technology. Compared with the traditional "barcode + magnetic stripe" technology, the application of RFID technology for book management is a huge innovation and upgrade. RFID has many features, which can allow libraries to provide more and more humanized services. So, this paper mainly studies the application of RFID technology in the field of libraries, taking the UHF RFID tags currently prevalent in large libraries as the main point of this research. It builds a security system for borrowing and returning management, so as to better manage the library. The results show that most of the experimental groups that pass the safety gate have a goodness of fit exceeding 0.9. The intelligent management of books can be effectively realized based on UHF RFID tags.

“…The main task of the tag antenna is to efficiently scatter the received power back from the interrogator. In this regard, ideal matching between the tag antenna and integrated circuit (IC) chip is essential to maximize the power transmission [26]. Generally, the impedance of the IC chip that is integrated with the tag's antenna has a high negative reactance (50 to 200 Ω) and low resistance (3 to 150 Ω).…”

“…When performing the simulation, the antenna was mounted on a 20 𝑐𝑚 × 20 𝑐𝑚 perfect electrical conductor (PEC) surface with a total thickness of 1 mm. Notably, the tag performance in terms of reflection coefficient, gain, radiation pattern, directivity, realized gain, or read range, is not affected by changing the thickness of the backing metallic surface [26].…”

This article presents a novel miniature interdigitated ultra-high frequency (UHF) radio frequency identification (RFID) tag antenna that can be placed on metallic objects. The tag structure comprises two horizontal strip lines, each loaded with seven identical open stubs, and an integrated circuit (IC) chip connected directly to the feed lines in the middle of the structure. The perfect match to the IC chip's impedance is realized by adjusting the length of the loaded open stubs and the spaces between the stubs. Molding the antenna's geometry can be applied to realize conjugated impedance with any sort of IC chip due to the flexibility of the tag structure. It is fabricated on a Polytetrafluoroethylene (PTFE) slab. Moreover, its structure does not involve any metallic vias or shorting walls, which makes its construction simple and suitable for mass production. The tag of the size of 55.2 𝑚𝑚 × 44.2 𝑚𝑚 × 1.5 𝑚𝑚 yields a total realized gain of −4.11 dB at the operating frequency while being placed on a 20 𝑐𝑚 × 20 𝑐𝑚 metallic plate. The measured detection distance is 8.14 m on metallic objects. A good match between the measured and simulated results is observed.INDEX TERMS Impedance matching, interdigitated structure, metal mountable tag antenna, miniature UHF tag antenna.

“…The main principle of the Hash-Lock protocol proposed by Erman et al and Oner et al is to use metaID instead of real tag ID. The randomized Hash-Lock protocol proposed by Weis is based on a randomized response mechanism [21,22]. There is also a digital library RFID protocol proposed by David et al It is authenticated by a pseudorandom function based on preshared secrets.…”

The logistics traceability system can cover the whole process of the product from the source of production to the consumption cycle. By distinguishing the key nodes of the product in the logistics sales process, the data information of the production and storage of the corresponding product is collected and entered at the corresponding node, so that the entire process is visible and controllable. On the basis of determining the overall system plan, this paper designs and develops the UHF RFID reader system and traceability system platform. In terms of the reader system, by analyzing its core functions and performance index requirements, the overall design scheme and frame structure of the reader system’s software and hardware are determined. The main control circuit is based on the STM32F103RET6 single-chip microcomputer; the RF transceiver circuit is based on the MagicRF M100. Simultaneously, we design a variety of communication circuits including LoRa and RJ45 to facilitate wireless communication with the traceability platform. In terms of software, through the research and analysis of the EPC Class-1 Generation-2 protocol standard, the multitag anticollision algorithm—Q algorithm—is adopted. This algorithm has the advantages of high recognition efficiency and a large number of successfully recognized tags per unit time. According to the design plan, the system is wirelessly networked in the B/S mode and the product information collected through RFID technology is transmitted to the management level to dynamically understand the information dynamics of logistics in real time. Using radio frequency, computer network, communication, and other technologies, the hardware and software systems of the system are integrated. The performance indicators of the hardware system are tested through experiments, and the design indicators are compared to prove the feasibility of the equipment application. After setting up the local area network and configuring the server configuration, the traceability system was accessed and the verification of the basic functions of the system was completed. The test results show that the low-cost universal RFID wireless logistics terminal has high accuracy and real-time performance in the process of logistics traceability.
