A credit card is borrowed from a spectator as you explain about fraud and credit cards. You then literally PEEL the magnetic swipe up from the spectator's card revealing the plastic underneath, explaining that all the spectator's information is contained on the swipe. You then seal the swipe back down and return the card unharmed. A great gag for SHOCK VALUE - You will do it just to see the expression on their face - the reaction is priceless.
