Barcode

A barcode is an optically readable code made up of bars and spaces that represents information in a machine-readable form. It belongs to automatic identification and is usually captured with a barcode scanner. Unlike RFID, a barcode generally requires a direct line of sight to the code and is usually read individually. It typically contains item numbers, batch data or serial numbers and therefore supports data capture in production and logistics. Barcode systems are widely used because they are simple to implement and well suited to many standard processes. A barcode is used above all where objects are visibly labelled and process steps need to be captured reliably, quickly and with little technical effort.
