A bar code is used to identify a product or item. That's all. Other information associated with that bar code is held on the computer server that is linked to the bar code scanner. That other information could include what the item is, its price, brand, size/weight, and many other particulars. The scanner is able to identify the item, and once the bar code has been used for that, the computer server does the rest.
