QR code

Originally invented in 1994 by Denso Wave, the Quick response code, or QR code, is a two-dimensional barcode that has a larger storage capacity than the standard UPC. Its uses include product packaging, advertisements, and labeling of products on the shelves of retail stores. A QR code reader app can be installed on a smartphone, allowing the user to scan the QR code and view the data stored in it; often information about a product or a direct forward to a website.


The QR code technology was originally developed in Japan, for use in their automotive industry.
