QR Codes
QR or Quick Response Codes
I have used the Google Chart API to generate Quick Response (QR) codes on every page of this site.
QR Codes are a type of barcode that most phones to read (using their built-in camera and a suitable program). I have used them to code the address for each page so you can easily transfer it to a mobile phone.
Depending on your phone, you will need to install a QR Code reader - I can recommend "QR Droid" for Android devices and Qrafter on the iPhone. Using both applications, you point your camera at the code at it will take you to the page in the browser (you will need to select "Open" if you are using QR Droid).
If you find a location on this site that you are thinking about visiting, just point your mobile at the QR Code and get the page on your phone - then take all the details with you!
