ABSTRACT:
A method of rapidly identifying RFID tags in an RFID system including a reader and a plurality of RFID tags, the tags having respective IDs formed of a plurality of bit locations, the method comprising determining in the reader which bit locations do not add to the uniqueness of the IDs of the tags; and ignoring data in bit locations that do not add to the uniqueness of the IDs of the tags. An RFID system comprising a plurality of RFID tags, the tags having respective IDs formed of a plurality of bit locations; and an RFID reader configured to communicate with the RFID tags, the reader being configured to determine which bit locations do not add to the uniqueness of the IDs of the tags, and to ignore data in bit locations that do not add to the uniqueness of the IDs of the tags.
