Method for identification of tags and anti-collision, and RFID tag using the same

摘要

tag should initiate the recognition method in RFID systems. Tag recognition method to recognize the tag by generating the query tree for Q between the RFID reader and the tag is receiving a response message to the query message from the tag to the step and the RFID reader transmits a query message to the tag comprising the steps , in reverse order and generates a tree of the query string (string) having the tag . It can be generated in reverse order with respect to the query tree having the tag ID based on the query tree protocol, reduce the time it takes to recognize all the tags within the identification area of the RFID reader by reducing the number of collisions between the tags .
