A person freely chooses a card from a deck of Face up playing cards. They're freely chosen card is then laid face up on an ordinary card box so that their card is in full view the entire time you explain to them before the trick began you made a prediction by putting a sticker on the back of one card. The spectator then deals all the cards face down trying to find the one card with the sticker on it to their surprise none of the cards have a sticker on it. You then tell The spectator to turn over their freely chosen card and when they do to their surprise their card has a sticker on the back proving that you knew they were going to pick that card. Everything can then be examined at the end.
