Designed For Automatic Scanning Of Information

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 indicate many information such as the country of manufacture, manufacturer, product name, production date, book classification number, mail start and end location, category, date, etc. Widely used.

Bar code technology (BCT) is an automatic identification technology produced and developed in the application practice of computers. It is designed to realize automatic scanning of information, and it is an effective means to achieve fast, accurate and reliable data collection. The application of barcode technology solves the bottleneck of data entry and data collection, and provides favorable technical support for logistics management. A bar code is a symbol composed of a set of regular bars and corresponding characters, which is used to represent certain information. The core content of barcode technology is to realize the automatic identification of the machine by reading these barcode symbols with photoelectric scanning equipment, and quickly and accurately entering data into the computer for data processing, thereby achieving the purpose of automatic management. The research objects of bar code technology include five parts: standard symbol technology, automatic identification technology, coding rules, printing technology and application system design.
