Well, you sure came off as an angry guy would have.

Yes I realize what goes on in such a place.
and as said. it is just a basic system to keep track of employees.
The machines can easily be avoided with a few rules of sensor placement.
anyways and noises can be muffled from the sensors pretty easily.
anyway.
It was just a thought so you can think about it more or you can just
call it a waste.
Personally I don't think it would be a waste.
