Bar code is a graphic identifier that arranges a number of black bars and blanks with different widths according to certain coding rules to represent a group of information. Common bar codes are parallel lines composed of black bars (referred to as bars) and white bars (referred to as spaces) with great differences in reflectivity. Barcode can indicate the country of production, manufacturer, commodity name, date of production, book classification number, starting and ending place, category, date and many other information, so it has been widely used in many fields such as commodity circulation, book management, postal management, banking system and so on.
