Abstract
A system and method for reading a two-dimensional barcode symbology. The two-dimensional barcode symbology has lines of data, each of the lines having several bars and spaces, each of the bars and spaces having a width. The method comprises scanning one of the lines using a CCD optical scanning head to obtain a scanned line. The bars and spaces in the scanned line are then converted into element time intervals, each of the element time intervals corresponding to, and representing the width of, one of the bars and spaces, thereby obtaining a converted line. For the converted line, a predefined prefix message, followed by the element time intervals, followed by a predefined suffix message are then output from the CCD optical scanning head to a processor.
