I have a friend who uses an electronic key fob to enter and exit his apartment building. The fob isn’t metal, but it grants access electronically.
He occasionally engages in private activities.
My question is: Does this key fob log every entry/exit? He’s cautious with cell phones and leaves them at home, but wonders if the key fob could potentially cause problems.
Yes. the system logs every entry/exit by keyfob.
Whether the building managers associate those fobs with individuals or even know how to look at the log is a different discussion entirely.
That said: If the building cares enough to have a lock on the door then they have a camera too and THAT is much more likely to be recorded. So if your “friend” depends on people not knowing he is entering or exiting his building for whatever reason… good luck with that.
Fun story time: I used to work at a facility that was VERY strict about people badging in and even out of many areas. At one point it came up in a safety debrief that there was no way to log who was inside or outside of an area… that required badging in and out. Could see someone’s brain cell trigger in real time as they proceeded to ask a lot of very pointed questions that boiled down to:
They had an access control list that was checked. They did not know how to access the log files to know when that list was checked or even the result of a check. The person who asked questions was pushed out of the company because it was easier.
