In this paper a radio frequency identification and detection (RFID) based library management system was developed that will enhance the use and management of library, the services being rendered can be managed with the help of software and hardware tools. This system use RFID technology to track books information in the library and the number of people that access the library. The device consists majorly of a RFID reader, a Bluetooth module, a microcontroller and the materials to be tracked are tagged with a RFID (a transponder). B The unique IDs are stored in a PC running an application with other information on the materials into a database. B Through these processes, books, library users with their information as well as their tag ID can easily be used for cataloging and user authentication. The device is designed to be mobile so that mixed books on shelves can easily be sorted out as the RFID reader moves across them. A model of the system was built, tested with several data and the result showed satisfactory improvement in the efficiency of the library management system.
