Universal Product Code
On April 3, 1973, Woodland at IBM developed the linear barcode, which
was adopted as the Universal Product Code, or UPC. UPC is the original
bar codes used for items sold in the United States and Canada stores.
The first item being a pack of Wrigley's Juicy Fruit chewing gum on June
26, 1974. They are probably the most recognizable code, seen on most
items at the local supermarket. UPC-A is a numeric-only bar code where
every digit is represented by a seven-bit sequence and is encoded with a
series of alternating bars and spaces. The UPC-A code includes an
automatic checksum, which verifies whether errors occurred during
transmission or storage of the data. The positioning and the value of
the digits have been standardized by a grocery industry committee.
