RFID tag and RFID reader for anti-collision and operating method thereof

The RFID tag and RFID reader for anti-collision, and their method of operation are disclosed. RFID tags for collision avoidance according to the present invention, the mode switching for switching the tag transmitter, the current mode that sent the response signals and the tag data of the tag receiver, the tag identification signal received by the tag identification signal from the RFID reader to a predetermined mode, by the unit, and if the response signal transmitted by the tag transmitter is a predetermined number, the mode switching unit comprises a control unit for switching to the mode. Thus, to prevent the collision of a small number of RFID tags from the RFID reader and is also available with a faster recognition. RFID, tags, readers, contact, collision avoidance
