UPC E Barcode (Universal Product Code)
UPC E barcode (also known as the "zero suppression version") allows manufactuers to encode a limited number of unique 12-digit product codes in six digits. The six digits are enclosed between two left-hand guard bars and three right-hand guard bars. The check character is encoded by the character set pattern of the six data digits.
