Almost certainly. You'd have to go out of your way to find a keyfob system that doesn't. I administer a keyfob system at work, and I can tell you exactly whose key was used on which doors and at what times.
In emergency cases most holograms can be shut off to match increased energy demands by weapons and shields.
Disengage the safety protocols and suddenly you've got weapons and shield emitters than ought to work just as well as their material counterparts, but can't be damaged (or any damage can be instantly reset). We know that holograms can be projected into space so the only limitation would be the range of the holoemitters.
White noise. I bought a white noise machine years ago when I lived near a large emergency room that had ambulances going by all day every day. It really helped with the sirens, and when I moved away I kept using the machine. My brain now interprets the white noise as profound silence, and I sleep so deeply that I don't know how I ever got by without it.
Oh, what sad times are these when passing ruffians can say "Ni" at will to old ladies.
