TAG ANTI-COLLISION METHOD, READER APPARATUS AND SYSTEM FOR RFID SYSTEMS WITH MULTI-PACKET RECEPTION CAPABILITY

摘要

According to the present invention, disclosed is a method for enabling an RFID reader to prevent collisions of a plurality of RFID tags. The method comprises a step of varying a length of a collision recovery slot to enable data transmission of at least one recognized tag in the collision recovery slot, which is successful in recognizing a plurality of tags even though a collision is generated due to a simultaneous response of at least two tags in one slot.
