We have cards and I handed out several just yesterday. I am checking out the Q-code on the back of the card. The q-code is the square thing that looks like black snow. A phone with the right app can instantly translate that to a contact information and they can save it to their contact list. It can have all sorts of information embedded in it. The front of the card is the analog part for people that are still in the 20th century and just want to read it.
