Snapdat is a creative app that allows an user to send digital business cards to people. The receiver, by email obtains a digital picture of the business card as well as a vCard attachment for importing into their address book. This is a handy application to have when you are caught off guard and don’t have a business card on hand. Using a “SnapID” you can share your cards with other Snapdat users and retain a directory of all the cards you have received. The receiver does not need an account with Snapdat in order to receive one. [Free – iTunes link]
