Great idea. Definitely the bot should have a business card scanner slot (and maybe a way to prevent every Tom, Dick, and Harry from inserting his business card). I recall an amusing discussion about this on Slashdot a few years back. It would be great to have one of these at a conference, but someone pointed out, you'd need a way to distinguish people-bots from actual robots, e.g. Roomba.
