You think of it as the annoying “beeping” noise at the grocery store, however the invention of the barcode revolutionized the retail industry. Before June 26th, 1974, all store transactions and pricing were completed manually. This all changed when Clyde Dawson walked into a Marsh’s supermarket in Troy, Ohio to pick up a 10-pack of Wrigley’s Juicy Fruit chewing gum. The pack of gum with a printed bar code ran across the UPC scanner at 8:01 A.M. and rang up 67 cents. NCR (a Dayton corporation) installed the first cash register that could read bar codes and is a main reason that the Dayton-area town was chosen for the first site. While other technologies such as QR codes and RFID chips have been developed since 1974, the barcode is still the most widely used today.
