I had one gig where I had more access to the building than the building's owner and company ceo.
But the real sense of power came the day I realized I could trap anyone in the company into a concrete stairwell with locked steel doors by revoking keycard access while they were between floors. I had a emergency lever/opener added to the ground floor door - I don't know how that got past fire inspection in the first place.
I've always wanted a door to nothing in particular with a triple deadbolt eye scan and pinpad access but its all for show just so people wonder what's in there and really you just tap a card to unlock it all.
I work in construction and currently work on the restructuration of an active airport, with various worksite around the airport. I have a very cool badge that clearly states that I can access almost every place.
Regularly, when I'm in a part of the airport that is in activity, I have people asking me directions, and I'm like :
"No, I don't know where gate 15 is, but I can tell you everything about the beam above your head if it helps..."
I worked at a five star hotel before. It was awesome going from the lavish, marble surroundings and air conditioning , through one set of doors into the kitchen, down the stairs and out to the barren concrete walls and flickering lights of the staff area and infrastructure parts of the hotel.
Oh i don’t have one 😆 but it sure seems useful to open some doors you’re not supposed to !
It is the fancy toy version though. There are cheaper devices that do some of the same things, although I’m not sure I’ve seen anything else with all the features yet.
