A barcode is a graphic identifier that arranges multiple black bars and spaces of varying widths according to certain coding rules to express a group of information.
A common bar code is a pattern of parallel lines formed by black bars (short for short) and white bars (short for short) with very different reflectances.
The bar code can mark many information such as the country of manufacture, manufacturer, product name, production date, book classification number, starting and ending address, category, date, etc.
Therefore, it has been widely used in many fields such as commodity circulation, book management, postal management, and banking systems.
