Bar-code scanners are used widely at point-of-sale terminals in retail stores. A handheld scanner or bar-code pen is moved across the code, or the code itself is moved by hand across a scanner built into a checkout counter or other surface, and the computer stores or immediately processes the data in the bar code. After identifying the product through its bar code, the computer determines its price and feeds that information into the cash register. Optical scanners are also used in fax machines and to input graphic material directly into personal computers. See also OCR
