A first communicating section communicates with a mobile terminal through first non-contact communication protocol having a first communication range. A mobile terminal has a telephone function via a telephone network. A second communicating section communicates with the mobile terminal through second non-contact communication protocol having a second communication range greater than the first communication range. A public-line communicating section transmits data via the telephone network. When executed by a processor, the instructions cause the processor to perform: acquiring destination information from the mobile terminal via the first communicating section, the destination information being associated with a counterpart apparatus connected to the telephone network; acquiring subject data from the mobile terminal via the second communicating section, the subject data being a subject of transmission to the destination information; and controlling the public-line communicating section to transmit transmission data corresponding to the subject data to the counterpart apparatus at the destination information.
