The company to install the time attendance security door but than before installation that do not know how much to the company when convenient, install the time attendance security door I was worried that if not convenient before can do it, now like I was thinking it is overrated. Our company before installing the one but there is no way compared with a time attendance security door, either from above or from the quality of the above functions are not at a level, it seems the future is to keep pace with the times is OK, otherwise one day is to be eliminated to the society yet, such a good product will be missed.
