Interesting concept. After spending the last week at Startup Riot and LessConf, intensely socializing with several hundred people, I'm not convinced this would have helped much. The one thing that stands out is taking a photo of the person, though I'm not sure I'd feel comfortable handing my phone to a stranger (nor would they).

I still hand business cards to people, but only after 2-3 minutes of conversation and only as a means to prevent having to spell my name and email/twitter in a crowded, noisy environment. I collect all of the cards I get and batch process them later, following folks on twitter, adding contacts, etc. This systems works much better for me and seems more efficient than typing into my phone.
