Communication control method of RFID reader

摘要

PURPOSE: A method for controlling an RFID(Radio Frequency ID) reader is provided to set a long communication time within a time range for which the reception collision rate is reduced, thereby efficiently reducing the reception collision rate. CONSTITUTION: A session is set, which initializes RFID tags after persistence time(S701). The persistence time of the RFID tags is acquired while communicating with RFID tags(S702). RFID tags communicates for the persistence time(S704). The communication is interrupted in a fixed delay time after passing the persistence time(S707). The final two steps are repetitively executed.
