Abstract

A technique of preventing occurrence of interference even when a plurality of RFID antennas are used simultaneously. Each RFID antenna is attached with a calibration RFID tag. A combination of RFID antennas that causes a problem is acquired based on whether information held by the calibration RFID tag can be read from each of the RFID antennas that have performed reading simultaneously. Then, an RFID antenna use procedure is generated such that the RFID antennas in the acquired combination are not used simultaneously. Each RFID antenna is operated according to the generated use procedure.
