alternative spelling for barcode
From the black and white vertical strips that supermarkets put on products so that when you get to the checkout, you or the checkout man/girl/person can put it under the optical scanner, and the supermarket's software will update its database, and the cash register will put it on your bill. "Bar code" is usually spelt 'barcode' these days pal, whatever your spell check program says.
