The UPC code was selected in 1973 by NRMA as their standard and has become the World Wide Standard that we all know today as the UPC Uniform Product Code.In 1971, after the IBM IRD engineers completed the development and building phase of the project they began in 1969, they released the equipment to the IRD manufacturing group in Dayton N. to begin producing the plastic magnetic striped credit and ID cards.After a frustrating day in the laboratory, trying to get the right adhesive, he came home with several pieces of magnetic tape and several plastic cards.As he walked in the door at home, his wife Dorothea was ironing clothing.The Delta Distance C Optical Bar Code was developed by the IBM Systems Development Division working at Research Triangle Park in Raleigh North Carolina headed up by George J. NRMA wanted an optically readable code that could be printed on products allowing purchasers to rapidly "check out" at the new electronic cash register/checkout counters being developed.

In the 1950s, magnetic recording of digital computer data on plastic tape coated with iron oxide was invented.The cards were then brought into the secured area and placed in "hoppers" at the beginning of the production line.The tape reels containing the data were then installed on the modified IBM 360 computer prior to beginning the encoding, embossing and verification of the cards.A magnetic stripe card is a type of card capable of storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card.

The magnetic stripe, sometimes called swipe card or magstripe, is read by swiping past a magnetic reading head.

Of the many optical bar codes submitted to NRMA by IBM and other companies, NRMA finally selected the later version of the IBM bar code known as the Delta Distance D Optical Bar Code format.
