When the server determines to permit the additional registration, the server transmits a piece of authentication permission information A to the mobile terminal. Receiving the authentication permission information, the mobile terminal registers the intrinsic information of the added meter and transmits the authentication permission information B to the added meter. Receiving the authentication permission information B, the added meter registers the intrinsic information of the mobile terminal as the permitted terminal. |
