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).<p>I recall an amusing discussion about this on Slashdot a few years back.  It would be <i>great</i> to have one of these at a conference, but someone pointed out, you&#x27;d need a way to distinguish people-bots from actual robots, e.g. Roomba.
