European Article Numbering
International standard bar code for retail food packages corresponding to the
Universal Product Code (UPC) in the United States. UPC is a subset of EAN,
and a reader equipped to read EAN can also read UPC. A reader equipped to
read UPC may not decode EAN. The EAN and UPC symbols were developed
by IBM and introduced into the market in 1971. The US adopted UPC in 1973;
EAN was adopted in 1976. EAN is now also called IAN (International Article
Numbering).
