Abstract
A bar code symbol reading system includes a memory for storing a plurality of reading gate locations, each reading gate location defining coordinates for a reading gate area surrounding one of the bar code symbols. The memory also stores a lookup table containing an identifier for the object and a pointer to configuration data relating each reading gate for the object to a specific component on the object. The object is scanned by a charge-coupled device scanner for scanning each bar code symbol according to the stored reading gate locations. A processor determines the identifier for each object and relates each read bar code symbol to a component on the object based on the configuration data.
