A spectator chooses a card that magically moves to a phone, leaving the spectator holding a blank card. The transfer is reversed and the card vanishes from the phone and the spectator is again holding his card.
You will need an App called MxPlayer to accomplish this plus a bit of sleight of hand. Several short MP4 files, to create the appearance and vanish of a card face from the phone's screen, are included in the download.
