There is a system of card entrance - the card has been delivered, the card has kicked on the reader, the door opens, you take and enter, the system has taken into account how much you came. The accountant alone takes the card, picks, but does not open the door and enters through the gate... and then wonder - why her department of personnel walk tries to put... the door then did not open, the system believes that she did not enter the logs is reflected - Access is provided (picks the card) and the Passage (opened the door), and she has the only access to the entire car center only provided... because it enters not through the door.... and the shadows all in panic - for the whole month she has only exits from work, no entrances.
