Abstract

PURPOSE:To attain the functions of plural personal identification ID cards just with a single sheet of card by storing plural pieces of personal ID information and reading out the desired personal ID information after collation of a due person with an optional reading action, an ID number, etc. CONSTITUTION:An AC key 14 on a personal ID card 10 is turned on and an ID number is supplied with ten keys 13. Then a collation key 16 is operated. Thus the ID number supplied through a keyboard 11 is set to an X register 27 via an input control part 22. The ID number written to the register 27 is compared with the ID number set at a PIN memory 26 through a comparison part 29. When the coincidence is obtained from said comparison, the next key input operation is possible. Thus a numerical code corresponding to a desired credit company, for example, is supplied by means of ten keys 13. A CPU 24 reads the name and the account of said credit company out of a personal ID information memory 28 and displays them at a display part 12. Thus it is possible to secure the functions of plural personal ID cards from just a single sheet of card.

Description

[Detailed description of the invention] [Technical field of the invention] [Prior art and its problems] In recent years, it has been called the cashless era, and by using cards issued by credit companies, etc.
It is now possible to purchase products without handling cash.

Currently, each credit card company issues its own credit card, and each store has a different credit card that can be used at each store. Therefore, in order to be able to perform card transactions at any store, customers create separate cards for each credit card company and store them in a dedicated card holder or the like. Therefore, the number of people is -2
You will have 0 to 30 cards.

However, having a card from each credit card company as in the conventional method is as follows: a. Handling the cards is troublesome.

b. The number of cards increases, making it heavier and bulkier.

C1 It is troublesome to search for a desired card.

There are other problems.

[Object of the Invention] The present invention has been made in view of the above points, and provides an electronic personal identification card and display method thereof that allows one card to have the functions of multiple personal identification cards such as credit cards. The purpose is to provide

[Summary of the Invention] According to the present invention, a plurality of pieces of personal identification information are stored, and desired personal identification information can be read out after verifying the person using a personal identification number or the like by performing an arbitrary successive operation.

[Embodiment of the Invention] An embodiment of the present invention will be described below with reference to the drawings. First, the external structure of the personal identification card 1o will be explained with reference to FIG. The personal identification card 1o is configured using, for example, an IC card, and is provided with a keyboard 11 and a display section 12 on its upper surface. The keyboard 11 includes, for example, a numeric keypad 13, an AC key (all clear key) 14 that also serves as the power ON key and - key, various function keys 15 for instructing calculation contents, and a collation key 16.
It is equipped with Further, the display section 12 uses, for example, a liquid crystal display element, and is capable of displaying characters such as alphabets and kana in addition to numbers.

Next, the IC circuit constructed in the personal identification card 10 will be explained with reference to FIG. 2. In FIG. 2, reference numeral 21 denotes a pass line, to which the keyboard 11 is connected via an input control section 22 and the display section 12 is connected via a display control section 23. A display buffer 231 is provided within the display control section 23 . The pass line 21 also receives input from the CPU 24 that controls the operation of each part and performs arithmetic processing, an RTR memory 25 that stores the number of data re-inputs, a PIN memory 26 that stores and sets a PIN, and the keyboard 11. An X register 27 that temporarily stores a personal identification number, and a personal identification information memory 28 that stores a plurality of pieces of personal identification information are connected. An arbitrary PIN is set in the PIN memory 26 by the card user, and its memory contents are stored in the comparator 2 along with the data held in the X register 21.
Sent to 9. Then, the comparison result of this comparison section 29 is C
Sent to P U 24. Further, the personal identification information memory 28 stores, for example, personal identification information regarding a credit card subscribed to by the card user. For example, the personal identification information memory 28 is provided with three areas a1, a2, and a3 as shown in FIG. The name of the credit card company is written in area a2, and the account number of each credit card company is written in area a3. Although not shown, the personal identification card 10 is provided with a battery for operating each of the circuits described above. Personal identification card 1 configured as above
0 has a normal calculation function as well as a credit card function.

Next, the operation of the above embodiment will be explained with reference to the flowchart of FIG. When using the personal identification card 10 as a credit card when purchasing goods, the card user first turns on the power by operating the AC key 14 which also serves as an ON key. By operating this AC key 14,
When the power is turned on, the RTR memory 25 in the personal identification card 10 is cleared as shown in step A1 in FIG. This RTR memory 25 is for counting the number of times the password is input when the password does not match, and the password can be mismatched up to four times, for example. Next, the card user inputs the password using the numeric keypad 13 as shown in step A2, and then operates the verification key 16. The password entered from the keyboard 11 is set in the X register 27 via the input control section 22.

Then, by operating the verification key 16, the password is verified as shown in step A3. That is, the password written in the X register 27 and the password preset in the PIN memory 26 are sent to the comparison section 29, and it is determined whether or not they match, as shown in step A4. . If they do not match, the process proceeds to step A5, where the contents of the RTR memory 25 are incremented by "+1", and then, in step 86, it is determined whether the contents of the RTR memory 25 have reached "5". The contents of the RTR memory 25 are “5”.
”, the process advances to step A7, and the display section 12
An error message will be displayed and you will be asked to re-enter your PIN.

If the password does not match even after re-entering the password and the contents of the RTR memory 25 reach "5",
It is determined that the personal identification card 10 is being used illegally, and processing to invalidate the card is performed as shown in step 88. If it is determined in step A4 that the password written in the X register 27 and the password set in the PIN memory 26 match, the next key manual operation becomes possible. Therefore, as shown in step A9, by operating the numeric keypad 13, input the numerical code corresponding to the desired credit card company. When the numerical code is input in step A9 above, the CP
As shown in step AIO, the U 24 searches the area a1 of the personal identification information memory 28 to check whether or not the corresponding numerical value is stored.If the corresponding numerical value is not stored, the process proceeds to step A5, and the RTR memory Add 1 to the content of 25. However, if it is determined in step AIO that there is a corresponding value, step A11
, reads out the credit card company name and account number corresponding to the corresponding numerical values from the personal identification information memory 28, writes them to the display buffer 231 of the display control section 23, and displays them on the display section 12.
to be displayed. After that, as shown in step A12, RT
The contents of the R memory 25 are cleared and the process returns to step A2.

As described above, a desired credit card company name and its account number can be displayed on the display section 12 of the personal identification card 10. The store side confirms the credit card company name and its account number displayed on the display section 12, and thereafter processes the product sales in the same manner as in the conventional case.

In the above embodiment, a case has been described in which personal identification information related to a credit card is stored in the personal identification information memory 28 and the personal identification card 10 is used as a credit card, but the storage contents of the personal identification information memory 28 may be changed. This allows it to be used as another card. For example, 1) For licenses ■ Car driver's license ■ Marine license ■ Aircraft license (■ Other general licenses 2) As a cash card 3) Personal identification card ■ Something equivalent to a health insurance card (including national pension etc.) ) ■ Pizza (nationality, etc.) → Worldwide response ■ This can be implemented in other areas, etc.

In addition, in the above embodiment, a 2-digit numerical code was used as the code corresponding to the personal identification information, but this number of digits is 3.
It may be a digit or four digits, and it may also be an alphabetic code (possible in the case of a card equipped with an alphabetic key) instead of a numeric code.

[Effects of the Invention] As detailed above, according to the present invention, a plurality of pieces of personal identification information can be stored, and desired personal identification information can be read out by an arbitrary reading operation after verifying the identity using a PIN number or the like. Therefore, one card can have the functions of multiple personal identification cards such as credit cards. In addition, by verifying the identity using a PIN number, etc., and then specifying a code corresponding to various types of authentication information, only the specified personal identification information is read out from memory and displayed, so that the cardholder can enter the PIN number and Unless you know the codes that correspond to each type of certification information, it is impossible to display the desired personal identification information, and even if the card is stolen, the personal identification information cannot be read by anyone other than the cardholder. There is very little risk of this occurring.
