THE EAN-13 barcode system is used in 85 countries, making it the most popular product scanning system of its kind in the world. It works by representing numbers as a series of seven vertical lines. Each of the seven lines is either black or white, and the sequence of lines forms a pattern which is recognized as a particular digit when scanned by a computer. Every product is assigned a unique thirteen-digit number (ten digits for the product itself, a check digit, and a couple of flag characters to indicate which organization assigned the number).
