A QR Code is a 2D matrix code created by the Japanese corporation Denso-Wave in 1994. The "QR" is derived from "Quick Response", as the creator intended the code to allow its contents to be decoded at high speed. QR Codes are currently the most popular type of two dimensional code in Japan. Their popularity is increasing with applications like storing addresses, URLs and business card contact information that can be captured and utilized by mobile phones equipped with a camera.
