Why was the QR code invented?

Masahiro Hara works for a company called Denso Wave, and part of his job was to come up with a way to track automobile parts. At the time, the company had a contract with Toyota, and keeping track of all the parts was a tall order. 

A simple barcode was being used at the time, but it can only hold so much information. Leaving boxes covered in barcodes and employees scanning several codes for one box left a lot of room for error.

Masahiro says that one day over a game being played in the lunchroom with coworkers, he realized that the codes being used in the game could easily be translated into his work. 

A development team and Masahiro worked to develop the QR code to store more information than a barcode and make the process more efficient. 

Instead of using several barcodes for a single item, these 2D barcodes that consisted of black and white squares could hold an infinite amount of information and leave less room for error since workers only needed to scan a QR code once. 

How has the QR code changed over the years?

The QR code has spread globally since its invention in 1994. It is safe to say that it has been picked up and accepted by businesses and the general public alike as a means of storing personal information, marketing, healthcare, and so much more. 

The appearance of the QR code has also changed over the years. In many places, you will still find the typical black-and-white codes with blocks in three corners. You may also notice that some QR codes are smaller, larger, colored, and may even contain brand logos.
