RFID MANAGEMENT SYSTEM, RFID READER DEVICE, RFID SYNCHRONIZATION CONTROL DEVICE, RFID MANAGEMENT DEVICE, AND RFID MANAGEMENT METHOD

摘要

PROBLEM TO BE SOLVED: To provide an RFID management system capable of correctly reading tag information of an RFID tag by preventing interference, even when multiple RFID reader devices and RFID tags are used in the same radio communication area.;SOLUTION: The RFID management system 1 includes: multiple RFID reader devices 5 for reading tag information of the RFID tags 4 attached to multiple products 3; an RFID synchronization control device 8 for outputting a synchronization signal, for synchronization between respective RFID reader devices 5 by using a predetermined radio channel to the multiple RFID reader devices 5, in a predetermined time interval; and an RFID management device 9 connected to the multiple RFID reader devices 5 and the RFID synchronization control device 8 for managing to prevent the multiple RFID reader devices 5 from simultaneously emitting radio waves to the RFID tags 4.;COPYRIGHT: (C)2010,JPO&INPIT
