The control circuit CPU writes data such as talking detail and talking start date in an EEPROM in the IC card ICCD connected to the key telephone set KT-m. When the talking is finished, the control circuit KPU of the key telephone set KT-m detects it. Then a talking charge is added to the talking detail stored at the acquisition of a trunk line in the IC card connected to the key telephone set KT-m for storage.
