To say the business cards are "old school" - or whatever is sort of naive. Okay - so what's the alternative? None that I know of. Granted, people don't keep "Rolodexes" anymore (those are too old-school). Considering they use PIMs, Outlook, iPhones, whatever - they key is integrating the two.
What would seem to make a hell of a lot of sense to me, would be if there was some sort of a standard for putting those 2D barcodes on the back of a business card, so people could quickly load them into their phone or PC via camera scanner software.
Yea, maybe then business cards could be obsolete I guess, in that someone could flash their card, and one could just scan it with their phone. (As opposed to physically needing to give someone a card).
You can use http://fonet.mobi/ to display your contact information as 2D code and another user can his smartphone to read the 2d code and save the data as CSV file. after that you load the file in your contact file directly.
