Some of these identification cards have an expiration date and an expiration date. However, with this type of conventional identification card, it is not possible to determine whether the expiration date is valid or invalid by the card itself, and the user must memorize the expiration date. For this reason, there has been a problem that the identification card may be misused or used without knowing that it has expired. Furthermore, conventional identification cards have the problem that they do not have any functions on their own, and are therefore a nuisance when carried around, resulting in a low portability rate.

Next, the operation of the above embodiment will be explained with reference to charts 70 in FIGS. 4 and 5. For the identification card 1 configured as described above, the password and expiration date are written in the PROM 15 from the terminal device in advance. At this time, the current time is set in the clock section 26, and the current date information is set in the calendar section 27. That is, gate signals a and b are sent from the control unit 21 based on a command from an external terminal device.
is selectively outputted to the AND circuits 29 and 28, and the calendar information and timing information sent from the external terminal device via the connector section 2 and the interface 22 are sent to the calendar section 27.
, set in the clock section 26. Therefore, normally, the signal output from the control section 21 to the signal line Ll is 0°', the output of the inverter 41 is 1'', and the AND circuit 3
It is entered as 0. Also, flip-flop FF1
, FF2 have also been reset, and their outputs are both OP. For this reason, the output of the inverter 40 is inputted to the AND circuit 30 as 1'', and its gate 1- is opened. The data is sent to the liquid crystal display device 3 through the display device 3 and displayed on the time/calendar display section 5 as shown in FIG. 1(a).At this time, as shown in step A2 of FIG. The presence or absence of a daily change signal is checked, and if there is a daily change signal, the calendar information (year, month, day) counted by the calendar unit 27 is updated as shown in step A3. Proceeding to step A4, the expiration date stored in the PROM 15 is sent to the comparison circuit 32, and the number of days remaining until the expiration date is obtained by subtracting "the expiration date - the current day", and the remaining number of days and the number of days in one month are calculated. Compare the size relationship with.

If the remaining number of days is less than one month, the process returns to step A1 and the same operation as above is repeated. In addition, the above step A
In step 4, when it is determined that the number of days remaining until the expiration date is one month, the process proceeds to step A5, sets the flip-flop FFI, inputs the "1" signal to the AND circuit 33, and outputs the signal from the control section 21. This enables transfer of operation commands to the blinking control circuit 34. After that, the process returns to step A1 and repeats the same operation. If it is determined in step A4 that the number of days remaining until the expiration date is less than one month, the process proceeds to step A6, where the comparison circuit 32 determines whether or not the expiration date matches the date data of the current day. . In step 80, if it is determined that the expiration date has not yet been reached, the process returns to step A1 and the same operation is repeated. Then, in step 86, if it is determined that the current day has reached the expiration date, the process proceeds to step A7.
The output of the comparison circuit 32 resets the flip-flop FF1 and sets the flip-flop FF2. Next, the process proceeds to step 88, where a card invalidation symbol lighting process is performed. That is, the flip-flop FF2
When set, an operation command is sent to the lighting control circuit 35. As a result, the lighting control circuit 35 operates and outputs a lighting signal for the LIMIT mark 7 to the liquid crystal display device 3 via the OR circuit 36.

Moreover, the set output of the above flip-flop FF2 is as follows.
An operation command is given to the invalid display register 37, and the gate of the AND circuit 38 is opened. Also, at this time, inverter 4
The output of 0 becomes 1101+, and the gates of AND circuits 30 and 31 are closed. Therefore, the invalid display data rEJ held in the invalid display register 37 is sent to the liquid crystal display device [3 via the AND circuit 38 and the OR circuit 39, and the time and
It is displayed on the calendar display section 5. That is, when the expiration date of the identification card 1 has passed, the LI
MIT mark 7 lights up and invalid display data rE
J is displayed on all digits of the time/calendar display section 5. This allows the card user to know that the identification card 1 has expired and is no longer valid.

Furthermore, the set output of the flip-flop FF2 is
The information is sent to the control unit 21, and the card invalidation process shown in step 80 is performed in this Ill111 unit 21.

However, during normal use of the identification card 1,
As described above, the current time is displayed on the liquid crystal display device 3. If you operate the DATE key 4 in this state, the current date will be displayed on the liquid crystal display 3, and if the expiration date is within one month, the LIMIT mark 7 will be displayed.
is displayed blinking. That is, when the DATE key 4 is operated as shown in the flowchart of FIG.
1, it is determined whether the flip-flop FFs is set. This flip-flop FF1 is the fourth
As explained in the flowchart in the figure, it is set in step A5 when the expiration date is within one month. Therefore, if it is determined in step B1 that the flip 70-tube FFs are set, the process proceeds to step B2 to perform allocation point reduction processing. flip flop FFI
is set, the output signal is given to the AND circuit 33, so the signal output from the control unit 21 to the signal line L+ in response to the operation of the DATE key 4 flashes via the AND circuit 33. It is sent to the control circuit 34 as an operation command. Therefore, the blinking control circuit 34 operates, and the L I M I T is sent to the liquid crystal display device 3 via the OR circuit 36.
Outputs a blinking signal for mark 7.

Therefore, as shown in FIG. 1(b), while the DATE key 4 is being operated, the LIMIT mark 7 is displayed blinking.

Further, a signal outputted from the signal line 1 from the 1llllIiia section 21 by the operation of the DATE key 4 is inputted to the AND circuit 31 to open its gate. At this time, the output of the inverter 41 becomes 'O°', and the gate of the AND circuit 30 is closed. Therefore, the calendar information output from the calendar section 21 is sent to the liquid crystal display device 3 via the AND circuit 31 and the OR circuit 39, and is displayed on the time/calendar display section 5 as shown in FIG. 1(b). . Also, DATE
When the key 4 is operated, if the period until the expiration date is longer than one month, the flip 70 knob FF1 has not been set, so the process advances from step B1 to step B3, and only the calendar information is displayed. When the DATE key 4 is released, the time display returns to the normal time display state shown in FIG. 1(a).

In addition, when using the identification card 1, the identification card 1 is attached to an external terminal device, and the password is inputted from the key input section. This key-entered password is sent from the terminal device via the connector section 2 and the interface 22.
Written to AM 14.

Then, the control unit 21 operates according to instructions from the terminal device, and uses the password and RAM stored in advance in the PROM 15.
14 is read out to the comparison circuit 23 for a match comparison, and the comparison result is sent to the terminal device. By this recognition process of the personal identification number, it is possible to determine whether the user of the identification card is correct or not.

In the above embodiment, data is exchanged with the external terminal device using the connector section 2, but other methods such as light, electromagnetic waves, etc. may be used instead of the connector. In addition, in the above embodiment, the current date is subtracted from the expiration date stored in the RAM 14, and it is determined based on the subtraction result whether the expiration date is within one month. PROM the date data from one month before
15 may be stored. Further, in the above embodiment, the liquid crystal display device I3 is used to notify the expiration date, but a buzzer or the like may be used for notification.

[Effects of the Invention] As detailed above, according to the present invention, a clock function is added to the identification card, and this clock function is used to determine and notify the expiration date of the card. It is possible to provide an identification card that can determine the expiration date on the card itself and notify the user of the expiration date, prevent misuse of the card, and has a time limit function that can improve the portability rate.
