Technology Briefs
Barcode systems are not designed to duplicate the human visual capabilities, like OCR (Optical Character Recognition) systems which require complex imaging and recognition schemes, but to replace it with components designed with readily available and low cost technology.
Having been used in commerce and elsewhere for over 50 years, bar codes have a proven track record to make the operation of businesses around the world more effective.
