When you are publicising your web site, it helps to put the QR code on your publicity material. This way, people who have a mobile phone with a camera and the right software can just point to the QR code and reach your website without having to type the URL.
But what is a QR Code?
The QR code is a special 2D image with the URL of the web site encoded in it. When the mobile phone camera points to it, the underlying software interpretes this as a URL and automatically loads the site in its browser window.
You can test it now. We have reproduced the QR code of our mobile site to the right. Just aim with your mobile camera and bingo – the site will load in your browser. Look ma – no typing!
