<p>A multi-function IC card (MFC) is compatible with multimedia cards and SD cards because of the two-line stagger of connector terminals (#1 - #13) on a card substrate (1), and the multi-function is realized because a memory card unit (3) and a SIM (subscriber identity module) card unit (4) are mounted by connecting them to respective predetermined terminals of the connector terminals (#1 #13). The memory card unit (3) and the SIM card unit (4) respectively have separate storage areas for secret codes for security. This realizes multiple functions of a single IC card having different security levels. By adopting a plural-line arrangement of the connector terminals represented by the stagger, a relatively simple construction of the card slot can be adopted, in which slot terminals are arranged in a single line as a whole by alternately changing the protrusions of the slot terminals to the stagger.</p> |
