Universal Product Code (UPC)

A Universal Product Code (UPC) is a standardized barcode used to identify products quickly and accurately at checkout. It consists of a series of black and white lines of varying widths that encode a unique number assigned to each product. When scanned with a barcode reader, the UPC helps stores retrieve product information such as price and inventory instantly. This system streamlines retail operations, reduces errors, and ensures consistent tracking of products across different locations and supply chains.
