I just came to this company, I really did not think ah, the company inside the time attendance security door is so much ah, and every time attendance security door are guarded, they just stood there to check, I think this is really good but, not random, people inside the company are many, so I think this system is particularly good, anyway, in my opinion, our company inside the time attendance security door are very useful, and we work on the card is not what import influence, is really very convenient. So I think this is the company’s own choice is very good.
