What is a barcode?

The barcode, barcode or EAN (European Article Number), describes an electronically readable font. This barcode consists of bars and gaps of different widths, which are arranged parallel to each other. This form of representation contains binary symbols or data and can therefore be read by scanners or cameras with the appropriate software and subsequently processed electronically.

Information behind the barcode:

The individual strokes conceal important information for tracking a product. When the barcode is scanned and processed electronically, a sequence of numbers can be seen, this sequence of numbers is assigned to each product and so the product information can be read from the individual bars. Most often, the barcode is located on the back of a product and can represent, for example, the name of a book.

Sequence of a barcode:

  1. Product is produced
  2. Will be barcoded
  3. On delivery the code is read out
  4. Product leaves the database of the producer
  5. Will be scanned and recorded at the next dealer
  6. Passes through the checkout system at the end and goes to the customer
