Abstract:
A method and a system are described for improved reading of Radio Frequency Identification (RFID) tags using correcting codes on sets of electronic tags. A reading device requests information from each of a set of electronic tags. The information includes an identification code and a portion of a codeword, the codeword contains a coded message with identification codes of all tags in the set. The information is received from a subset of the set of tags. Portions of the codeword from the received tag information of the subset of tags are assembled. A decoding component to decode the assembled portions and to construct the coded message from the assembled portions of the codeword. Information is individually received from a remaining set of the tags in the set of tags. An enterprise system processes the received information from all tags in the set.
