摘要
Bar codes, comprised of black and white stripes, are shown to be a finite topic, and the optimum bar code methodology is binary coded binary, BCB. Binary digits are utilized to represent bar coded messages and each binary digit is immediately complemented, forming two independent but binarily complemented messages in one bar code symbol. BCB represents given information in less space than, e.g., Interleaved 2 of 5 and Code 39, while using the same x width (the width of a module), and BCB is far more versatile and is easier and less expensive to print and scan. BCB avoids misreads more reliably and achieves a dramatically higher first time read rate through use of error correcting bar codes.
