As a result, card holders and station staff can check the reservation information as a ticket at any time with a single IC card.

(4) Use Operation as a Ticket FIG. 3 is a diagram showing an example of a display mode in various processing steps of FIG. 1, and the use operation will be described with reference to FIG.

At the start of boarding, that is, when entering from the ticket gate, if the user inputs an instruction to display the face description information from the key input unit 11, for example, presses the `` inquiry '' key, the mode determination unit 24 outputs the output signal S24b. This is given to the display control unit 29. Then, the display control unit 29 displays the note description information output from the note description information storage unit 28 in the scroll display area A2 of the display unit 12, and displays a symbol corresponding to the state of the use history flag unit 30 on the display unit 12. Works to display in the usage history display area A1.

Here, the symbol corresponding to the state of the use history flag unit 30 is, for example, E when the valid flag unit 30a is “1” (however, it is indicated by a circle E in FIG. 3) and “0”. Is not displayed, the use flag 30b is U when the use flag 30b is "1" (however, the circle U is displayed in FIG. 3), and is not displayed when the use flag 30b is "0", and the ticket check flag 30c is "1". Is C (however, it is displayed as a circle C in FIG. 3), and when "0", it is not displayed. therefore,
When entering from the ticket gate, only the valid flag 30a is "1", so that the display as shown in FIGS. That is, FIG. 3a1 is displayed first, and when there is subsequent data D overflowing from the display digit, the data is scrolled and displayed sequentially within the scroll display area A2. Next, for example, when the "#" key is pressed, FIG. 3a2 is displayed. When there is subsequent data D, scroll display is performed in the same manner as in FIG. 3a1, and when the "#" key is further pressed, Fig. 3 a3
Is displayed, during which the most significant digit is always E display.

The station staff receiving this IC card 10 checks that the E mark indicating that the validity is valid is displayed in the most significant digit and, if necessary, displays the date and the like. After inputting a request to use the use flag from 11, for example, simultaneously pressing the “flag” key and the numerical value “1” key, and inputting the use PIN from the key input unit 11, the use P
The IN is stored in the input password storage unit 21, and the match determination unit 23 determines whether or not the input PIN code storage unit 31 matches the use PIN 31 b stored in advance in the issuer PIN storage unit 31. When the match determination unit 23 determines “match”, the use flag operation mode is instructed as described above, and the output history signal S24c of the mode determination unit 24 opens the gate of the use history flag unit 30. Therefore, "1" is set to the use flag 30b.
Thereafter, the IC card 10 is returned to the card holder, and entry from the ticket gate is permitted.

Next, if an in-vehicle inspection ticket is required, the station staff or conductor who received the IC card 10 from the card holder,
Input from the key input unit 11 that the user wants to display the information on the ticket surface,
For example, an "inquiry" key is pressed. Then, the valid flag
Since both 30a and the use flag 30b are "1", FIG. 3b1 in which the upper two digits of the display unit 12 are EU should be displayed. The display contents b1, b2, and b3 of the scroll display area A2 of the display unit 12 are the same as those shown in FIGS.

The conductor also indicates that an E mark indicating that it is valid in the upper two digits and a U mark indicating that use has started are displayed, and that necessary information such as a train name, a seat number, and a boarding section are displayed. After confirming from the display contents displayed in the scroll display area A2, after inputting that the ticket inspection flag operation is desired from the key input unit 11, for example, after simultaneously pressing the "flag" key and the numerical value "2" key, Then, a ticket inspection PIN is input from the key input unit 11. Thus, in the same manner as described in the section at the start of boarding, the match determination unit 23 determines the match / mismatch between the input ticket PIN and the previously registered ticket PIN 31c. If it is determined to be “match”, “1” is set to the ticket inspection flag 30c. Thereafter, the IC card 10 is returned to the cardholder. If the displayed contents do not meet the required conditions, take appropriate measures according to the situation, such as settlement of the shortage, etc., set “1” to the inspection flag 30c, and then own the IC card 10. To the person.

At the end of the boarding, that is, when exiting from the ticket gate, the card holder inputs from the key input unit 11 an indication that he / she wants to display the information on the face of the ticket, for example, presses an "inquiry" key. In the case of the IC card 10 that has received a ticket inspection, the valid flag 30a, the use flag 30b, and the ticket inspection flag 30c are all “1”.
FIG. 3 c1 in which the upper three digits of the display unit 12 are EUC is displayed. The display contents of FIGS. 3 c2 and c3 and the scroll display area A2 showing the subsequent display examples are the same as those shown in FIGS. In the case of an IC card 10 that has not received a ticket inspection, the ticket inspection flag 30
Since c is "0", the display is as shown in FIGS.

When the IC card 10 is presented to the station staff, the station staff can present an E mark indicating that the card is valid, a U mark indicating that use has been started, and a C mark or boarding date as required.
After confirming the boarding section and the like, after inputting a request to delete the flag from the key input unit 11, for example, simultaneously pressing the “flag” key and the numerical value “0” key, the delete PIN is input from the key input unit 11. Enter Then, in the same manner as described in the section at the start of boarding, the match determination unit 23 determines whether the input erase PIN matches the previously registered erase PIN 31a. When it is determined to be “match”, when all of the valid flag 30a, the use flag 30b, and the ticket inspection flag 30c are reset to “0”, the contents stored in the ticket description information storage unit 28 are erased. Thereafter, the IC card 10 is returned to the card holder, and the exit from the ticket gate is permitted. If the displayed contents do not satisfy the necessary conditions, after performing appropriate measures according to the situation, such as settlement of the shortage, etc., input that the flag is to be cleared from the key input unit 11 and enter the valid flag. IC card after resetting 30a, use flag 30b and ticket inspection flag 30c to “0” to erase the information written on the face
Return 10.

In the above card operation, if the used PIN, ticket inspection PIN, and erased PIN entered by the station staff do not match the previously stored PIN, the display unit 12 prompts the user to re-enter the PIN. And accept the re-entry of the PIN.
