What is a QR code?
A QR Code (it stands for "Quick Response") is a mobile phone readable barcode
In its simplest sense think "print based hypertext link" -
simply encode a URL into the QR Code and then point a mobile phone
(or other camera-enabled mobile) at it. If the device has
had QR Code decoding software installed on it, it will
fire up its browser and go straight to that URL.
But it doesn't stop there - a QR Code can also contain a phone
number, an SMS message, V-Card data or just plain alphanumeric
text, and the scanning device will respond by opening up the
correct application to handle the encoded data appropriately
courtesy of the FNC1 Application Identifiers that are embedded in
the encoded data.
