This converted text is delivered by the scanner to a computer software system holding a database of the maker, cost, and quantity of all products sold. The decoder interprets that signal, validates the barcode using the check digit, and converts it into text. More specifically, the sensor in the barcode scanner detects the reflected light from the illumination system (the red light) and generates an analog signal that is sent to the decoder.

Businesses as massive as Wal-Mart and Amazon use barcode and scanners so do small-town and home businesses that need to keep track of where they’re sending their e-commerce orders.
