In this paper, the authors introduce the basic concept, development process, key technology of RFID (Radio-Frequency IDentification) and related theory. And in view of the key technology of RFID, anti-collision algorithm is analyzed. Tag collision algorithm is to solve the reading and writing implement effective communications within the scope of multiple tags at the same time, speaking, reading and writing for communication problems. Under the condition of keep a certain complexity and cost, minimize the search time, improve the efficiency of recognition, is the direction and trend of algorithms.
