Today marks the 57th anniversary of the day the first patent was made on the Bar Code.
Granted to American inventors Norman Joseph Woodland and Bernard Silver three years after it was filed, patent number 2,612,994 was for a pattern of concentric circles, rather than the set of straight lines used today.
The first trial of the bar code was in 1966, and in 1970 the familiar Universal Product Code (UPC) design, still used around the world, was agreed on as an industry standard.
The first item to be scanned using UPC was a packet of Wrigley's chewing gum at a supermarket in Troy, Ohio in June 1974.
