Today, with the development of science and technology, unmanned self-service terminal services have already covered all aspects of life. From self-service library borrowing and returning books to automatic ticket sales at subway stations and bank ATM self-service deposit and withdrawal, etc. There is a tendency to gradually replace manual services in multiple industries. RFID radio frequency identification technology is different from the traditional bar code relying on the photoelectric effect. It is a technology that can replace the existing bar code. The rfid nfc sticker is equipped with

The RFID library intelligent management system is based on the emerging electronic label technology, and it integrates identification of readers, books, documents, and library shelves, which makes it more convenient, efficient, and convenient between computer information and library documents, and reader services Management and service system. The system is guided by a brand new reader service concept and document management model, and aims at the actual needs and existing problems of library service work and document management, and fully realizes the intelligence and efficiency of library

The IC card refers to an integrated circuit card, and a general bus card is a kind of IC card. Generally, a common IC card uses radio frequency technology to communicate with an IC card reader. The IC card stores information by the integrated circuit in the card, and the magnetic card records information by the magnetic force in the card. The working principle is that the RF reader sends a set of electromagnetic waves of fixed frequency to the IC card. There is an LC series resonance circuit in the card, which has the same frequency as the frequency emitted by the reader. In this way, the L
