A second terminal device is used in a system including a server, a first terminal device, and the second terminal device. The second terminal device includes: a first command transmission unit configured to transmit a first command to the first terminal device via the server; a storage control unit configured to hold a first address and first authentication information of the first terminal device; a second command transmission unit configured to transmit a second command to the first address; a determination unit configured to determine whether a terminal device as a destination of the second command is the first terminal device, by using first response data from the terminal device and the first authentication information; and a third command transmission unit configured to transmit a third command to the first address if the terminal device is determined to be the first terminal device. |
