I'm in a building with a mere nine floors that has such a system (the only buttons in the elevators themselves are door open, door close and alarm). I imagine that the technology will increasingly appear in the smaller buildings as their elevators are built or refurbished.

Whenever I use those sorts of lifts I find it very unsettling - it's interesting, because floor buttons vs external destination buttons give me no more control over the lift, but as a user I become very anxious when my mechanism for "driving" the lift is taken away.

What if you need to visit someone on another floor?

There's touchscreens in the lift lobbies where you can select an override floor before scanning your pass.
