3rd QR post in - guess I should explain what it is:
A QR Code is a matrix code (or two-dimensional bar code) created by 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. Almost any phone with a camera and the use of an app like Beetagg can decode the message behind the QR.
