On October 7, 1952, American inventors Norman Joseph Woodland and Bernard Silver were granted US Patent # 2,612,994 for “Classification Apparatus and Method”, described as “Classification Article by Pattern Identification.” Today we know that “pattern identification” as barcodes. Woodland and Silver eventually sold their patent for just $ 15,000 although they were inducted into the inventor hall of fame. Bar codes were first used commercially in 1966 and evolved so rapidly that by 1970 there was a requirement to establish an industry standard regarding it. The company Logicon Inc. created the UGPIC code (Universal Grocery Products Identification Code) to achieve the implementation of the barcode throughout the industry. Monarch Marking, based in the United States, was the first company to produce barcode peripherals using UGPIC for retail. The British company Plessey Telecommunications followed suit by creating its own equipment later. The UGPIC was transformed to UPC (Universal Product Code), which is still used in the United States. The first piece of technology that UPC used was installed in a Marsh’s supermarket in Ohio and the first product passed through a barcode reader would be a packet of gum on June 26, 1974.
