It was a 10-pack (50 sticks) of chewing gum, purchased at a supermarket in Troy, Ohio, at 8:01 a.m. The Universal Product Code (UPC) is a barcode symbology that has been widely used all over the world for the tracking of trade items in stores. UPC (technically refers to UPC-A) is comprised by 12 digits that are uniquely assigned to each trade item.
