Shrinky dinks? Credit cards?? No need to try even that hard. True story: my uncle works for DHS, and right after he got hired there were a couple days before he got his ID card that unlocked the doors. He quickly realized, however, that the doors -- which unlock automatically as someone approaches from within -- could be opened by slipping a piece of paper between the door and the jamb, tripping the motion sensor. Try not to tell the terrorists.
