The Casa Margherita QR code is here

This codes can be read by mobile phones (with the correct gadget) and this will take them directly to the Casa Margherita website without the need to the URL. You can also link them to text. This makes it easier for people to take note of your business and remember the details as they are all stored on your mobile

I will be adding this to my business card all my other publicity materials over time.

Not bad for a partial luddite.
