ABSTRACT:
A data encoding/decoding scheme includes a plurality of bar code symbols each carrying a portion of the data in which improved error correction capabilities are incorporated. According to one aspect, once data codewords have been derived to form the symbols, a first set of data correction elements are derived from a first field, then a second set of error correction elements are derived from the data elements and the first set of error correction elements using a second, wider field.
