1. A method of reconstructing item identifier strings that identify items in a collection using information read from RFID tags affixed to the items, the method comprising:

  • receiving, using a processor, a plurality of data packets read from a batch of RFID tags, where each data packet includes redundancy provided by a coding scheme, where information for each RFID tag in the batch is shared among the RFID tags in the batch in the form of redundancy provided by the coding scheme, and where a code correction capability of the data packets enables the information of all of the RFID tags in the batch of RFID tags to be reconstructed by reading the data packets of a subset of the batch of RFID tags;

    reordering the received plurality of data packets using an item sequence number extracted from each of the received plurality of data packets using the processor;

    generating a code word from a set of code word elements comprising a code word element extracted from each of the received plurality of data packets using the processor; and

    extracting a plurality of item identifier strings from the code word using the processor, where the plurality of item identifier strings identify items in the collection.
