PURPOSE:To confirm the using condition of an IC card at a glance by providing a rewritable display part at the IC card and rewriting it related to the data in the inside of a memory simultaneously at the time of the changing of the data of the internal memory. CONSTITUTION:When a card 10 is inserted into a terminal equipment 30, the terminal 31 of the terminal equipment 30 is allowed to contact with the electrode of a module part 1 and the exchange of the data through the CPU of an IC card 10 is executed at the division of a data processor 33 by the control signal outputted by a reader/writer 32 of the terminal equipment 30. After the collation of a card such as the confirmation of an issuer, the confirmation of a boarding location, and a calculating processing such as a boarding distance and a charge are executed, the adjustment is executed, and the remainder is stored into the IC card 10. Simultaneously, the memory data of a memory part are read to a display converting device 34, here, converted to a display graphic and the remainder is displayed through a magnetic head 35 for recording at a display part 3 of the card 10. Since the remainder is always displayed at the surface of the card 10, even when the system is used for a book of tickets, any inconvenience does not exist and the system is very convenient at the time of an actual use. |
