POSITION INFORMATION DECISION APPARATUS OF RFID TAG AND THE METHOD THEREOF

摘要

PURPOSE: A location information determining apparatus and method of an RFID(Radio Frequency Identification) tag are provided to accurately grasp location information of a product while reducing an error of an antenna reader. CONSTITUTION: An RFID tag is included in a fixed space. RFID antennas(112-118, 122-128) receive an RFID tag signal. RFID readers(130, 140) receive a signal of the RFID antennas. A tag location determining unit(200) successively activates the RFID antennas and receives an RFID tag ID(Identification) and an RFID antenna ID received in the RFID readers. The tag location determining unit determines the location of the RFID tag according to recognition times of the RFID tag received by the RFID antennas.
