DEETS is an elegantly simple solution for sharing contact information, best described through an example.  Bill, a new business acquaintance asks Evan for his business card.  Evan responds, “I don’t use business cards and shows Bill his smartphone lock screen. Evan tells Bill, “Just take a picture of my screen and text it to 78 789.  DEETS will send you my contact card, then add it your address book. The whole process takes about 10 seconds.
