Every time before the end of the month, when worries me most, because I want to do the staff attendance, our company before there is no time attendance security door, so we are going to the attendance and the staff to check, this let me work with some difficulty. And they sometimes feel I give them less registration, inevitably some problems, then we give the leadership we installed time attendance security door, I think it is the time attendance security door, I work together more easily, and the time attendance security door above are recorded and I don ‘t have to worry about attendance, so I think the time attendance security door installation is really on.
