I liked the idea of the QR codes at UKMW09. I’ve seen them before, but never really understood how to use them. Was great to see an innovative way to use them at conferences (would love to see more of that). Only problem I had is there wasn’t a QR code reader for my phone (I know SHOCKING). I think as phones develop, more people will be able to use this and in the future instead of handing out business cards you will use QR codes instead – so hey, it’s good for the enviroment too!
