description A wireless communications terminal prevents radio interferences caused by other wireless communications concurrent with a contactless communication. A wireless communications terminal receives, in a contactless communication, a command from a reader/writer via a second wireless communications section, and analyzes the received command. The wireless communications terminal controls a wireless communications control section to deactivate or temporarily deactivate the function of a first wireless communications section depending on the analysis of the command. After the function of the first wireless communications section is deactivated or temporarily deactivated, the wireless communications terminal accesses a memory area of an IC card microcomputer system as specified by the command to perform a contactless communication.
