The present invention discloses a method and system for tallying tags in a radio frequency identification system. The method comprises: upon receiving a tallying command sent by the reader, the tags reflecting a first response message used for decoding and checking (S402); upon receiving the first response message, the reader sending a decoded random number (RN) if it decodes the first response message correctly; upon receiving the decoded RN, the tags reflecting a second response message containing tag ID information after confirming that the RN is consistent with their own RN (S405); and upon receiving the second response message, the reader confirming that the tallying is completed if the tag ID information contained in the second response message is correct (S407). |
