摘要
PURPOSE: A method for preventing collision between a fixing / movement reader in RFID system is provided to realize high correct recognition rate of a tag by preventing a inter-reader collision through communication time adjustment with the tags between a fixation-type reader and a mobile-type reader. CONSTITUTION: A fixation-type reader proceeds operation of tag recognition for TF hour(700). The fixation-type reader transmits an invitation message to a mobile-type reader before a periodic tag recognition operation(702). The mobile-type reader transmits an answer invitation message to a fixation-type reader(704). The fixation-type reader transmits a confirmation message to the mobile-type reader(706). The mobile-type reader recognizes the tag for TM hour(708).
