The barcode is a code that is based on the representation of a set of parallel lines of various thickness and spacing which together contain certain information. The barcode allows the quick recognition of an item in a unique, global and unambiguous way at a point in the logistic chain, so that it can carry out inventory or check its associated characteristics. There are different types of equipment used for a barcode: A barcode printer and a barcode reader or scanner. A barcode printer prints barcode labels that can be attached to or printed directly on physical objects. Barcode printers are commonly used to label packages before shipment, or to identify commercial items with UPC (Universal Product Code) codes. Barcode printers are manufactured for different markets. Industrial barcode printers are used in warehouses and factories. A bar code reader uses a laser to read the barcode and emits the number that shows the bar code, not the image. It consists of the scanner, a decoder and a cable or wifi antenna that acts as an interface between the decoder and the terminal or the computer. Almost all types are now available on the market as fixed, cable-bound hand scanners or as mobile acquisition devices.
