The initial idea didn’t come until 1949
University friends Bernard silver and Norman Woodland ‘coined’ the barcode in 1949. They were both students from pensylvania, United states. It wasn’t until over 20 years later, 1974, that barcodes were used in retail stores.
Chewing gum was the first supermarket product to use a barcode
The first use of a barcode as a UPC (Universal product code) was at an Ohio Supermarket in 1974. The product? A ten piece packet of Wrigleys chewing gum.
They used to serve very different purposes
The first commercial use of the barcode was in 1959, and it was used to label and sort rail cars. At the time, the barcode system we see today was known as ‘kartrak’, because of its very specific use!
It wasn’t always black and white!
The colour of barcodes; it’s fairly black and white nowadays. That wasn’t so back in 1959. As pictured above, although stripes were still read by and scanner, they were blue and Red!
