There are a variety of different types of bar codes. However, the U.P.C. symbol is the most recognized bar code in the United States, since it appears on almost every retail product. The U.P.C. symbol is the bar code representation of the UCC-12. (Universal Product Number) which consists of twelve numeric characters that uniquely identify a company's individual product. Although, the initial U.P.C. usage was focused on retail point of sale (POS), many other industries have adopted this coding structure.
