<p>PURPOSE:To surely perform entrance/leaving management to a specific floor by opening a door when use qualification data recorded on an IC card satisfies prescribed reference. CONSTITUTION:This system is equipped with a password collation part 3 which collates a password inputted by a user with the password recorded on the IC card, and file memory 8 on which the use qualification data is recorded. The use qualification data recorded on the IC card is collated with correspondent use qualification data in the file memory 8, and the opening/closing of the door is controlled based on those collation results. Furthermore, the expiration date of door entrance/leaving is attached as the use qualification data recorded on the file memory 8, and it is checked. Also, the number of times of closing of the door is recorded on the file memory 8, and a protective countermeasure is provided by writing door lock data and prohibiting access for the opening/ closing of the door when it exceeds the prescribed number of times.</p> |
