cards and invoice

My own cards and invoice. The cards were sent to print over two weeks back so hopefully they well come back soon. The design uses a QR code that can be scanned by a mobile phone and will add my contact details to the phone. I hesitated about using this as it dominates the graphics but I have had positive feedback from people I have shown this to so far. These are growing in popularity and i'm not the first to use these on business cards but its still fairly uncommon so should get me noticed. I think using QR codes might quickly become passé, so best to milk them while they are still fresh I think.

Also, its not just iphones that can use these, android phones, blackberry and even my cheap pay-as-you-go Nokia can scan it so I would say at least 50% of phones should.
