Abstract: An automatic position managing system is applied to a communication system which includes a plurality of telephone sets coupled to a private branch exchange. The automatic position managing system uses a radio card which is carried by a user and has the functions of storing information related to the user and transmitting the stored information by a radio signal. A first part supplies data to the private branch exchange in response to the radio signal received from the radio card and a second part automatically detects a position of the user carrying the radio card based on the data received from the first part via the private branch exchange by associating the user with the telephone set to which the first part is coupled.
