A Barcode is the small image of lines and spaces that is affixed to retail store items, identification cards, and postal mail to identify a particular product number, person or location. The code uses a sequence of vertical bars and spaces to represent numbers and other symbols. It is usually used to read the code. The reader uses a laser beam that is sensitive to the reflections from the line and space thickness and variation. With only some basic printing equipment and a readily available barcode scanner, businesses can use barcode technology to improve accuracy, speed and efficiency without significant expense
