Ask the spectator to choose a card and sign the back and the face of the card.
You then write an "X" on the back of the card, the spectator can rub it to prove it is real.
Miraculously the "X" can be removed and transferred to the hand of the spectator!
Without switches and using permanent markers.
Fully examinable and can be a souvenir
