How bout this for a business card service: 1. I create my "virtual business card" online and upload 5 pictures of myself 2. Someone meets me at a conference, takes my pic (in 5 secs), then uploads it (via mobile app or web) 3. Facial recognition confirms who I am and they get to download all my information to their address book
