Claim 11:
12. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to control a mobile terminal provided with a reader/writer to execute a control method, the method comprising:
transmitting, to an antenna device including a mobile terminal antenna that receives a radio wave output by the reader/writer, a plurality of IC card antennas that communicates with an IC card including an IC chip for the IC card that reads/writes data in a contactless manner in response to a command transmitted by the reader/writer, and a control circuit that operates by using power generated when the mobile terminal antenna receives the radio wave output by the reader/writer and controls enabling or disabling of each of the IC card antennas in response to the command transmitted by the reader/writer, the command for controlling enabling or disabling of the IC card antennas from the reader/writer,
wherein the control circuit includes a switch that is connected to each IC card antenna of the plurality of IC card antennas and switches enabling or disabling of the plurality of IC card antennas in response to the transmission of the command, a controller that controls the switch, and an internal IC chip that controls operation of the controller in response to the command and reads/writes data in a contactless manner in response to the command.
