You can make an access system foolproof, but not necessarily operator-proof..
If there is a way round it, they will find it.
When you use lightguard systems, trapped key systems, RFID/turnstiles, it usually needs 2 to get round it, as while one stays inside, the other has to knowingly reset the safety system. We had one where the tech "had" to go inside the light curtain area, to check the moving carriage, and he got the apprentice to go outside and reset the safety circuit while he checked the "local operation". Nobody got injured, but they both got spotted doing so, and disciplined.
A counting mat can go wrong, they will have a way to reset it, then it will become common practice...
