    Conditional messageFor example, if some alarm is not acknowledged for some time, it can be redistributed to some superior person.

    Program can work in client mode, so it is possible to make passive monitoring from any LAN point.

    Faster and easier guest check-in. Receptionist enter data in front office, and HARS receives commands for check in, check out and data change directly from front office.

    Energy management. FOS sends information about rooms reservation scheme, so HARS can handle additional level of energy savings.

    Phones control. HARS sends to FOS information when guest is in the room, so PMScan switch on phone line, and if guest is not in the room phone line can be used only for internal connections (inside hotel, hotels staff can not make phone calls from rooms).

    Prepare keycards in advance. It is possible to prepare keycards in advance (if large group of guests is expected).

    Makes possible to identify guest by keycard. POS points are equipped with special readers and guest can handle payment just with his keycard.
