In a warehouse, the barcode might encode an item’s size, color and other attributes, as well as its location, so the company has a detailed view of current inventory and can quickly fulfill orders or conduct physical inventory counts. A computer connected to the scanner has all the information on what item is associated with that unique combination of bars and spaces and may add, multiply or divide those numbers to identify the correct product, which shows up on the screen. The width of the black bars usually represents the numbers 0 or 1, while the sequence of those bars signifies a number between 0 and 9. and the European Article Number (EAN) in Europe.

Today, barcodes are found on not only household items that come from supermarkets or retail stores, but licenses, rental cars, checked luggage and hospital bands. Computers linked to scanners can read these codes and use the exact combination of bars, spaces and numbers to retrieve the data for that product. What Is a Barcode?Īt a basic level, a barcode is a square or rectangle with a combination of vertical black lines of varying thickness and height, white space and numbers that together identify specific products and their relevant information.
