Most barcodes are nothing more than "license plates" that identifies an item. The numbers and/or letters stored in the barcode are unique identifiers that, when read, can be used by a computer to look up additional information about the item. The price and description of the item is generally not stored in the barcode. The data is read from the barcode, sent to a computer, and the computer looks up the price and description of the item from the computer's database.
