Abstract

The present invention relates to an RFID reader and a method thereof, and an RFID data processing method. The RFID reader generates a specific query message to a plurality of RFIDs, receives a first response message corresponding to the query message from at least one RFID among the RFIDs, and sequentially identifies a tag ID of a collided RFID by using a collision solving message when a collision occurs according to the result of receiving a first response message. The RFID reader can quickly and accurately identify a plurality of RFIDs since it can eliminate an unnecessary time such as excessive no response slot generation or repeated rounds through a sequential identification process for the collided RFIDs.
