Trespassing

Trespassing is an incredible, moving effect! You place a piece of a card, or a folded bill, on top of an ID holder. Just pass your hand over, and it immediately goes inside the ID holder! Fast, clear, and visual. 

Your spectator may open and check the ID by themselves and they won't discover anything, as it is a completely regular ID holder! And, your hands are totally empty and clean. If you're in an environment where these kind of badges are in use, then it's a killer trick! (If not, it's a bit weird, so choose your location wisely!) You could use this ID holder normally for yourself and do the trick suddenly anytime, anywhere. Moreover, you could reset and redo the trick over and over again.
