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.
- Static QR Code: The actual destination website URL is placed directly into the QR code and can’t be modified.
- Dynamic QR Code: A short URL is placed into the QR code which then transparently re-directs the user to the intended destination website URL, with the short URL redirection destination URL able to be changed after the QR code has been created.
