<P>PROBLEM TO BE SOLVED: To provide a non-contact type IC card in which multiple types of non-contact type IC card functions such as a TYPE-A, TYPE-B, and FeliCa(TM) can be installed. <P>SOLUTION: A pulse counter 24 counts the wave number (number of amplitudes) of carrier waves within a fixed sampling period measured by a sampling timer 25. Based on this count value, it is determined whether the frequency of the received carrier waves are consistent with carrier waves used for communication in a TYPE-A module 30-1, a TYPE-B module 30-2, and a FeliCa(TM) module 30-3. When they are consistent, a CPU 29 controls a TYPE-A module 30-1, a TYPE-B module 30-2, and a FeliCa(TM) module 30-3 to sequentially start, and controls one of the modules in which analysis error in the received data is not generated in the initial response operation to be activated selectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
