An exchange data communication determining unit determines, based on a received reception wireless frame, whether or not a communication partner is an exchange partner with which the exchange data can be exchanged. Receiving a notice that exchange of the exchange data is possible, a data communication control unit executes a process for giving/receiving the exchange data. A machine identification information registration unit stores an MAC address of a portable game machine in an MAC address list saving area. Again, the wireless frame transmitting/receiving unit sets a transmission wireless frame and executes an exchange partner searching process. An exchange data communication determining unit determines whether or not an MAC address included in the received reception wireless frame is registered with the MAC address list saving area, and if it is registered, the data communication is terminated. |
