SPOTLIGHT How did Morse Code inspire the bar code system? June 26 Bar Codes Bar Codes Answer of the Day How did Morse Code inspire the bar code system? In 1948, two Drexel grad students, Bernard Silver and Norman Woodland, decided to come up with a system to record product information at the supermarket checkout counter. Drawing dots and dashes in the sand — á la Morse Code — Woodland pulled his fingers down from the symbols, making narrow lines from the dots and wider lines from the dashes. They used movie soundtrack technology to read the lines. Silver and Woodland received a patent for their system in October 1952. The system was tweaked and tested in several different industries, and on this date in 1974, a cashier swiped a 10-pack of Wrigleys Juicy Fruit gum across the scanner in the first commercial use of the UPC bar code. The pack of gum and the receipt are on display at the Smithsonian Institution in Washington, DC.
