To provide an order calling method for making it unnecessary for a person who wants to be accepted to wait for his or her turn in the neighborhood of an information desk, and for making it possible to call only the person who wants to be accepted in the neighborhood of the information desk without leaking his or her personal information to the others.

An acceptance order managing device 20 is provided with a short distance radio communication unit 26 and an auxiliary storage device 28. A reservation information data base 31 in the auxiliary storage device 28 stores personal information transmitted from the portable information terminal of a user, reservation numbers to be generated in the order of the reception of the personal information, and an information desk presence flag indicating whether or not the user enters a prescribed area including an information desk. When an information clerk calls the user, the record whose reservation number is the youngest among the records whose information desk presence flag is '1' is read, and calling information is transmitted to the portable information terminal corresponding to the reservation number. In the portable information terminal 10 which receives the calling information a calling unit 18 is driven to utter or vibrate.
