Zusammenfassung:	An IC card having a self-identification function in the card itself includes an input key for inputting a personal identification number (PIN), a comparator for comparing the PIN input via the input key with a prerecorded PIN. A transaction condition signal is produced when a match is found. An external terminal is provided for outputting to the outside of the card, e.g. a bank terminal, to enable a transaction using the card. An information storage circuit suitable for use in the IC card is also disclosed.
