A QR code (Quick Response Code) is a square or rectangular barcode that can be scanned using a mobile, desktop, or standalone QR reading device and will direct a user to a webpage, article, photo, video or other media in a matter of seconds (depending on connection speed). QR codes can be embedded on a website, printed out on business cards, post it notes or paper, as well as stored on a mobile device. The QR Code was created as a way to store more information than a barcode and to have that information accessed quickly.

QR Code History
QR Codes were released in 1994 by Denso Wave, and adopted by the Japanese automotive industry as a way of creating a more efficient work environment. In 1997, the QR Code was adopted as an AIM (Automatic Identification Manufacturer) standard and then in 1999 it was approved as a standard 2D code and used by the Japanese Automobile Manufacturers' Association and was adopted as an international standard. The QR Code is open source and is now used globally for business, industries, education and many other sectors.
