METHOD FOR IDENTIFICATION OF TAGS AND ANTI-COLLISION, AND RFID TAG USING THE SAME

摘要

A tag recognition method, an anti-collision method, and an RFID(Radio Frequency ID) tag using the same are provided to reduce time needed for recognizing all tags included in coverage of an RFID reader by reducing collision among the tags. An RFID reader transmits a query massage to a tag(S120). A response message to the query massage is received from the tag(S130). A query tree is generated in a reverse order of a character string of the tag.
