力。Next, the operation will be explained. When an IC card is inserted into a card reading device, the IC card is supplied with power from the device, and the information stored in the nonvolatile memory on the IC card is subjected to predetermined signal processing and taken into the reading device. Further, new information from the reading device is written into the nonvolatile memory after passing through predetermined signal processing. At this time, power supply to the IC card and 16-information exchange are performed by the IC card.
