Introduction
The RFID library tag is an intelligent label widely adopted in modern library management systems. This tag contains a miniature chip and antenna, capable of storing detailed information about the book, such as title, author, publication details, and a unique identification code. Compared to traditional barcodes, RFID tags offer features like contactless reading, rapid scanning, and long-distance recognition, significantly enhancing the efficiency of book borrowing and returning processes. Additionally, the RFID system enables self-service borrowing and returning, automated inventory management, and anti-theft monitoring, providing readers with a more convenient service experience while helping libraries reduce operational costs and improve management efficiency. With continuous technological advancements, RFID library tags are gradually becoming an essential component of smart library construction.
