Did not expect, then we have the time attendance security door, our company looks inside the system is not the same, every colleagues had to go to work, but no one complained of what, so I installed the time attendance security door common sense is right. The time attendance security door to us is also very good ah, because of the time attendance security door, we can see their work on time, time to pay, will not because of attendance problems and troubles, so I think it is very good, anyway. I think no matter what kind of company which has a time attendance security door is still very necessary.
