The performer hands half a deck of cards to a spectator and keeps the other half for himself.  Turning his back to the spectator, he asks him to freely pick any card among the cards that he has been given, remember it, and then slide it back anywhere among the magician’s cards. Once this is done, the magician turns around again, and without any suspicious moves, names the spectator’s card!
