Answer 1

Correct Answer - Option 1 : Norman Joseph Woodland

The correct answer is Norman Joseph Woodland.

• The first Barcode system was developed by Norman Joseph Woodland.
  • The barcode was invented by Norman Joseph Woodland and Bernard Silver and patented in the US in 1951.
  • The invention was based on Morse code that was extended to thin and thick bars.
  • Barcode contains information about a product like-
    •  price & weight of the product, date of manufacturing and expiry, name of the manufacturer.
  • Barcode is allocated by an international institution set up for this purpose.
  • Every product has a unique barcode all over the world.

• On June 26, 1974, the UPC barcode was used for the first time in Troy, Ohio, at Marsh Supermarket.
  • The first product that was scanned with the new barcode was a pack of Wrigley's Juicy Fruit chewing gum.
  • The choice of a pack of gum as the first product to be scanned wasn't just by chance. 
•  A barcode scanner will read this pattern of black and white bars and translate them into a line of test that your retail point of sale system can understand.
• Barcodes are applied to products as a means of quick identification.
• They are used in retail stores as part of the purchase process, in warehouses to track inventory, and on invoices to assist in accounting, among many other uses.
