Portable device

A portable device comprising:

• a wireless communication unit that comprises
• a first wireless communication processing unit of which communication distance is short, the first wireless communication unit being capable of performing high-speed communications and
• a second wireless communication processing unit of which communication distance is long compared with the first wireless communication unit, the second wireless communication unit being capable of performing low-speed communications;
• a communication control unit that performs communications with an external device via any one of the first wireless communication processing unit and the second wireless communication processing unit and controls at least a transmission of data to the external device;
• and
• a communication state judging unit that judges a communication state of the communications with the external device via any one of the first wireless communication processing unit and the second wireless communication processing unit, wherein
• the communication control unit performs switching between the communications with the external device via the first wireless communication processing unit and the communications with the external device via the second wireless communication processing unit based on at least one of the communication state judged by the communication state judging unit and a transmission data amount to be transmitted to the external device in order to control the transmission of data to the external device.

A portable device comprising:

• a wireless communication unit that performs a data transmission and reception with an external device that is brought to close to the portable device;
• and
• a communication control unit that performs a communication with the external device via the wireless communication unit and controls at least a transmission of data to the external device, wherein
• the wireless communication unit includes a first communication mode, in which a communication distance is short and high-speed communications are performed, and a second communication mode, in which a communication distance is long and low-speed communications are performed, and
• the communication control unit switches a communication mode between the first communication mode and the second communication mode based on a usage state of the portable device.
