  • Methods and apparatus for supplemental barcode detection and decoding
    Patent number: 6561426
    Abstract: A system for detecting and decoding a supplemental barcode accompanying a primary barcode. A supplemental barcode is affixed to a product in the vicinity of a primary barcode. A scanner in a barcode reading system, such as a point of sale system, scans for a primary barcode. Upon detection of a primary barcode, the system inserts a delay while attempting to detect a supplemental barcode. Upon detection of a secondary barcode, the primary and supplemental barcode information is processed, for example by sending the information to a terminal connected to the scanner. Upon expiration of the delay without detection of a supplemental barcode, the primary barcode information is processed.
    Type: Grant
