COMMUNICATION METHOD OF A PLURALITY OF RFID READERS WITHIN READER INTERFERENCE AREA

摘要

PURPOSE: A communication method for a plurality of RFID(Radio Frequency ID) readers arranged in a reader interference region is provided to perform communication with the RFID readers while an operation enable signal is activated after the operation enable signal is sequentially applied to the RFID reader. CONSTITUTION: A plurality of RFID reader(111-114) are connected with each other through an electric line(211) and the wireless network. The RFID readers communicate with RFID tags during permitted time. The RFID readers receive an operation enable signal from the outside. The communication is operated only when the operation enable signal is activated. One of the RFID readers is set as a master RFID reader. The operation enable signal sequentially actives the RFID readers from the master RFID reader.
