Apparatus for recognizing radio frequency identificationrfid and method thereof, and data processing method of rfid

The present invention relates to a data processing method of the RFID reader and a method and an electronic tag. The RFID reader of the invention receives the first response message is sent to a plurality of electronic tag generates a specific query message, corresponding to the RFIDs query message from at least one electronic tag of. Then, the first response message reception result, the tag ID of the electronic tag collision by using a collision solving message when a collision occurs and identifies sequentially. This, the RFID reader is able to quickly and accurately identify a plurality of electronic tag ID it is possible to eliminate an unnecessary time such as excessive no response slot generation or round loop through the sequential identification process with respect to the electronic tag that a collision We can expect the effect. Electronic tags, RFID, reader, READER, recognized RFID tag collision slots
