You have a security fob or card you hold to a sensor when hitting the floor button. Without it, floor won’t select. High rise building use them for many doors, like from garage, loading dock, to enter pool or gym, etc. so all residents will have them anyway. And each can be programmed to allow access to specific locations or not.
