What are QR codes ?
According to Wikipedia, a QR code is " a specific matrix bar code ( or two-dimensional code ), readable by dedicated QR bar code readers and camera phones. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be text, URL, or other data."
