    Sep 08, 2024
    Barcode recognition technology refers to the technology that uses photoelectric conversion equipment to identify barcodes.     A barcode is a sequence of wide bars, narrow bars and spaces. This sequence can represent a certain number and letter code. Barcodes can be printed on paper and other items, so they can be easily reproduced by photoelectric conversion equipment. Numerical and alphabetic information can be read by computers. Barcode technology mainly consists of three parts: scanning and reading, photoelectric conversion and decoding output to the computer.     In postal services, barcode recognition technology has been used in letter sorting, registered letter processing, express delivery automatic tracking, parcel processing and other tasks.     A barcode is a graphical identifier that expresses a set of information by arranging multiple black bars and blanks of varying widths according to certain encoding rules.     A common barcode is a parallel pattern composed of black bars (referred to as bars) and white bars (referred to as empty) with very different reflectivities. The barcode can mark the country of production of the item, manufacturer, product name, production date, and book classification number. , mail starting and ending locations, categories, dates and many other information, so it has been widely used in many fields such as commodity circulation, library management, postal management, banking systems, etc.
