Unlike barcodes, RFID tags can be embedded in the tracked objects and do not need to be within the line of sight of the reader. So it can be used to replace barcodes on library materials to store identifying information. Since RFID tags can be read even though they are covered by objects, a stack of books can be read simultaneously with high efficiency, reducing staff time to a large extent. With the Internet of Things (IOT) applying to library, RFID tags is gaining importance in library materials management. It is estimated that over 30 million library items worldwide now contain RFID tags.

With the diversity of sensors including Internet access modules (Wi-Fi, 2G/3G/4G, etc.) and RFID reader module embedded in specially designed Android handheld terminal, Android based UHF handheld reader (Android RFID reader) can read UHF RFID tags efficiently, make connection to Internet easily at anytime and anywhere and provide access to the IOT System for Library Materials Management for multi users synchronously. So it can be used as mobile RFID reader and installed with a library materials management application software as the entrance of IOT System for Library Materials Management.

An Internet of Things System for Library Materials Management was designed in this paper as an easy access to improve the efficiency of library materials management. It solves the problems in library materials management and meets the requirement of convenient access to library materials management system using Android RFID readers by both readers and librarians.
