Agreed, they would get an error along the lines of "can't read the card"... The actual balance is stored on a server somewhere, not on the card... I'd call them up and check the history, I'm sure it can be pulled up.
Maybe the TSA guys saw it in your luggage and went out and bought a round for break?
