RFID enables the implementation of a digital library management system

In library management, traditional manual methods have gradually been replaced by digital systems, utilizing barcode recognition, computer networks, and software technologies to enhance efficiency. However, challenges such as self-service book returns, rapid inventory, searching, and cataloging still persist, impacting library management and service quality. Consequently, the library sector is actively pursuing more advanced technologies to address these issues.

RFID (Radio Frequency Identification), or radio frequency identification technology, identifies specific targets and reads/writes related data through radio signals, enabling automatic recognition of target objects and retrieval of relevant data without requiring mechanical or optical contact.

RFID tags offer advantages such as waterproofing, resistance to magnetic fields, high-temperature tolerance, long service life, extended read range, encrypted tag data, large data storage capacity, and modifiable stored information. RFID readers are categorized into mobile and fixed types, widely utilized in fields like library management, access control systems, and food safety traceability.

1.3 Application of RFID Technology in Library Management

RFID technology utilizes radio frequency signals for data transmission and response, where RFID smart tags or ordinary RFID tags can transmit and store information. RFID smart tags consist of adhesive labels and ultra-thin radio frequency tags, combining the advantages of radio frequency technology and label printing. These smart tags can be programmed multiple times and adhere to the encoding rules established during their initial production.

RFID electronic tags can be categorized into low-frequency, high-frequency, ultra-high-frequency, and microwave tags based on their operating frequencies. Depending on the packaging form, electronic tags can be classified into credit card tags, linear tags, paper tags, glass tube tags, circular tags, and special-purpose irregular tags.

The RFID reader communicates wirelessly with the RFID electronic tag via an antenna, enabling the reading or writing of the tag's identification code and memory data. A typical RFID reader consists of a high-frequency module (transmitter and receiver), a control unit, and read/write antennas. Compared to barcodes, RFID features batch reading, rewritable data, and real-time response. Libraries can utilize RFID technology to achieve various contactless management functions, including data for readers and collections. In recent years, libraries have replaced barcode identification with RFID technology, improving operational efficiency and accuracy, but the fundamental nature of service models remains unchanged.
