"I suggest you also check Olocode (www.olocode.com) an alternative to QR code for contact management that does not require scanning with a camera phone nor an app to be downloaded.
Olocode takes minimal space on business cards and includes full contact details and your picture, while QR codes contain less than a tweet, hardly your full contact details and surely not a photo.
Imagine - as the user now has your picture in their contact book, whenever they look for you, call you or receive your call your smile will fill their screen!
Olocode can also be added to email signatures, scribble on a palm or piece of paper or spelled on the phone. It works on smartphones, PCs, Macs and tablets with no software to download and keeps people updated if your contact details change."
This seems great in concept but if I received a card with the "ABCD.1234" code on it, there is a pretty close to 0% chance that I am going to travel to olocode.com on my phone and type that in.
I would think the ultimate solution (until QR codes can contain more info) would be a QR Code that has a link to a website, which downloads a larger vCard file containing everything the olocode would have. Still get the nice quality picture etc.
