It is said that recently in the company to install a time attendance security door, I was still don’t believe, but I also feel that time attendance security door, is particularly convenient, because we are not on the time attendance security door, feeling it is no sense of security, but now with the time attendance security door if it really is particularly good, especially now that many companies are using this time attendance security door, the last time I went to a friend’s company to find friends, this is time attendance security door to block the door, so the time attendance security door also feel very good or very good use.
