Practically every item you purchase in a store has a barcode or Universal Product Code (UPC) on it. The code consists of a series of varying stripes readable by store scanners, known as the barcode, and a 12-digit series of numbers readable by humans, known as the UPC. You may find no rhyme or reason to the codes, but if you're familiar with them, there's a pattern which allows you to determine which company the barcode belongs to.
