This chapter reveals the role of radio frequency identification (RFID) in modern libraries, thus demonstrating the theoretical and practical concept of RFID; the utilization of RFID in global operations; RFID perspectives in modern libraries (i.e., operating cost, information technology infrastructure cost, skilled RFID workers, access rate, patron policy, data security, barcode factor, and patron issues); the applications of RFID in modern libraries (i.e., data management, circulation, inventory, assistance in searching and orientation, data accuracy and reliability, theft prevention, utilization statistics for serials, and personal service); and the significance of RFID in modern libraries. RFID solutions can be utilized to reduce the operating costs through decreasing labor costs, enhancing automation, improving tracking and tracing, and preventing the loss of materials. Applying the RFID will significantly improve educational performance and gain sustainable competitive advantage in modern libraries.
