The invention of barcodes provided a solution to this problem. Subsequently the POS system was developed, in which the price of an item of merchandise was displayed on the cash register automatically when the barcode on the item was scanned by an optical sensor, and information on the item was sent to a computer at the same time. As the use of barcodes spread, however, their limitations became apparent as well. The most prominent was the fact that a barcode can only hold 20 alphanumeric characters or so of information.

As a result of the growing demand for technology to lighten the burden on supermarket cashiers, a POS system was created. It was basically the newborn baby version of a Barcode that allowed for the scanning of individual items to be registered by a computer. Despite this effort, however, this still wasn’t enough. Supermarkets then faced another obstacle: Barcodes could only store up to around 20 alphanumeric characters of information and functioned with one dimension (one direction of coding). The invention of the QR Code can be contributed to the DENSO WAVE and their lead developer Masahiro Hara. They were contacted by supermarkets who realized the limits of these Barcodes and sought a way to make them more versatile and contain more information through the development of a 2-D Code (two directions of coding).

The reason QR codes were invented has everything to do with the type of barcode they replaced: the traditional UPC barcode. To this day, the Universal Product Code (UPC) barcode is still the most prevalent tracking tool on the planet. And their very beginnings lie in 1952, when Norman Woodland and Bernard Silver’s first patent was issued for barcode technology. At the time, it was known as linear scanning technology. And it looked like a bullseye. For two decades, the technology remained undeveloped and unused.Meanwhile, post-war American suburbs were booming. The birth of the supermarket to feed the suburban masses led to a unique logistical problem. How can so many individual items in one place be processed quickly?
