Some Airport security doors work like this. At an old job, I was on a project at an international airport and was given one of those cards to get you through all the doors. Bypass security, get down to poke the planes, etc. Slide the card and key in a code to get through. They gave us two codes: one to open the door, and another that opened the door and set off the silent alarm. |
