Before someone gives you his/her business card, ask him/her to secretly write any 3 digit number on the backside. You then remove your wallet from your pocket and open it up. You ask the person to place his or her card with the written number face down into your wallet’s compartment with the rest of the cards. You close the wallet and then place it into your pocket. You pause, then instantly tell that person his or her written number!

Works great with numbers, states, simple thought of objects. Very easy to perform; extremely deceptive…
