It is highly amusing how many keycard readers amount to "close this circuit between two wires hidden behind drywall". Or when they expose USB ports, or screw heads, or are protecting a glass door.

One of my favorites in a NY office design was the keycard passes through a door in a wall that was only a foot higher than the door, with plenty of open space above that (about 5-6'). Security theater isn't just the provenance of the TSA.

Key card entry. Motion detector to open the doors on the other side. Open to the air above the doorway. I could throw anything over the door and it would unlock for me.
