1. A mobile telephone which accommodates an IC card having a memory area for storing information regarding electronic money, the mobile telephone comprising:

  • a first wireless communications section operable to perform a mobile telephone communication via a communication network;

    a second wireless communications section operable to perform a contactless communication, which is independent of the mobile telephone communication, between a reader/writer provided in an automatic ticket gate, and the IC card when the IC card is placed over the automatic ticket gate;

    a wireless communications control section;

    operable to, in the case where said second wireless communications section accesses the memory area for storing the information regarding electronic money to perform processing for exchanging the electronic money with the reader/writer, when the IC card is placed over the automatic ticket gate, determine that a contactless communication that involves highly confidential information is to be performed by said second wireless communications section, cause a mobile telephone communication function of said first wireless communications section to be in a function deactivated mode where the mobile telephone communication function is not reactivated automatically, and complete the contactless communication, performed by said second wireless communications section, that involves highly confidential information; and

    operable to in the case where said second wireless communications section performs the contactless communication without accessing the memory area for storing the information regarding electronic money, when the IC card is placed over the automated ticket gate, cause a mobile telephone communication function of said first wireless communications section to be in a temporary deactivated mode where the mobile telephone communication function is reactivated automatically, and complete the contactless communication performed by said second wireless communications section; and

    a timer section operable to start timing when said wireless communications control section causes the mobile telephone communication function of said first wireless communications section to be in the temporary deactivated mode, said timer section being used for reactivation from the temporary deactivated mode,wherein, at a time when a predetermined time period has elapsed in a timer operation of said timer section, said wireless communication control section automatically returns said first wireless communication section from the temporary deactivated mode to a mode where a mobile telephone communication can be performed.
