METHOD FOR GENERATING RFID TAG ID FOR COLLISION AVOIDANCE AND RFID TAG HAVING ID FOR COLLISION AVOIDANCE

摘要

A method for generating an RFID tag id for collision avoidance and an RFID tag having ID for collision avoidance are provided to improve a tag recognition rate of an RFID reader. An RFID system is comprised of one or more tags and a reader. An index(n) of a frame size is initialized as 1(210). The number(m) of tags is divided by n-th power(fbn) of the frame size(220). It is determined whether a lot(Q) had a value smaller than 1(230). When the lot had the value smaller than 1, the current index is determined by a query level(250). A tag ID is balancedly allocated based on the determined query level(260).
