History of QR Codes

QR Codes were originally created in 1994 for the automotive industry as a method of tracking vehicle parts throughout the manufacturing process. In 2002, a group of mobile network providers, phone makers and various service businesses collaborated to utilize the cameras of cell phones as bar code scanners. The bar code of choice was inevitably the QR Code. By 2007 (5 years later), 90% of Japanese mobile users recognized QR codes and 50% were scanning them.

It wasn't until more recently that QR codes have become widely received throughout the world. We now find QR Codes being used in a variety of applications all over the world.
