ABSTRACT:
An optical reading apparatus for scanning and decoding data encoded in any of a plurality of types of 1D and 2D bar code symbols. A scanner generates successive blocks of scan data for storage in a scan memory. The scan memory stores at least one complete block of scan data in one address space thereof while a more current block of scan data is being stored in another address space thereof. A processor selects and decodes blocks of scan data in accordance with a selectable one of a plurality of scanning-decoding relationships, at least one of which is a tracking relationship.
