RESPONSE CONTROL METHOD OF RFID TAG, RFID SYSTEM, RFID TAG, RESPONSE CONTROL INFORMATION GENERATION PROGRAM, AND RESPONSE CONTROL PROGRAM

摘要

PPROBLEM TO BE SOLVED: To prevent responses from being retransmitted from the same RFID tag in transmitting a search command from a reader/writer and confirming RFID tags existing in a coverage area. PSOLUTION: An RFID tag reading control apparatus comprises a generation means for generating first response control information for determining whether an RFID tag has already transmitted a response or not and a transmission means for transmitting a search command for searching an RFID tag existing in a coverage area together with the generated first response control information in transmitting the search command to the RFID tag.
