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.
They know who has what fob so that if Fred in apartment 201 loses his fob they can invalidate it in the system and issue a new fob to Fred.
