Ic card

Abstract

A multifunction IC card (MFC) has compatibility with a multimedia card, an SD card, etc. in that connector terminals (# 1 through # 13 ) are disposed on a card substrate ( 1 ) in two rows in a zigzag fashion, and realizes multifunction facilities in that a memory card unit ( 3 ) and an SIM (Subscriber Identity Module) card unit ( 4 ) are respectively connected and mounted to predetermined terminals of the connector terminals (# 1 through # 13 ). The memory card unit ( 3 ) and the SIM card unit ( 4 ) are respectively separately provided with areas for storing secret codes for security. Thus, one IC card is capable of implementing multifunction facilities different in security level. Owing to the adoption of a plural-column layout corresponding to a form typified by the zigzag fashion in an array of the connector terminals, a relatively simple structure can be adopted in a card slot.
