JPH08279029A - Ic card with password number input device - Google Patents

Abstract

PURPOSE: To prevent the card from illegally being used by releasing a function for controlling the output or input of data by inputting a identification number on a numeric input panel. CONSTITUTION: The numeric input panel is mounted on the top surface part of the IC card 1 and the function for controlling the input and output of data can be released by inputting the identification number through the panel, and an input/output program for temporarily released data puts the card back to the original state where the input/output control function operates a certain time later through an internal timer function. Further, an LED 3 is added and made to illuminate when the correct identification number is inputted, thereby indicating that the card is currently usable. The card user confirms that the card is usable by looking at the LED 3 and then begins to use the card. Even when the card is left as it is after its use, the card is put back to the state wherein the card is unusable unless the identification number is inputted again a previously set time later, and the LED 3 also turns off to indicates the unusable state.

Description

Detailed Description of the Invention

[0001]

It is an object of the present invention to prevent the IC card from being used illegally by preventing the IC card from being used unless the password is input to the password input device attached to the IC card. The purpose is to do.

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for preventing unauthorized use of an IC card when handling information management using a contact type or non-contact type IC card. For example, it is assumed that the IC card is used in a toll payment system such as a bank, a credit company, a store where a reading register is installed, an expressway, or a security system.

[0003]

2. Description of the Related Art Since the conventional IC card does not have a fraudulent use prevention device in the card itself, if the person who should originally use the card lost, lost or stolen the card,
There was no way to prevent the confidentiality and unauthorized use of the information in the IC card.

[0004]

SUMMARY OF THE INVENTION According to the present invention, even if an IC card is lost / lost or stolen, the IC card cannot be used without inputting a personal identification number, and a certain period of time has passed. If this is done, the IC card cannot be used without re-entering the personal identification number, so even if the IC card is lost immediately after the personal identification number is entered, it is possible to prevent unauthorized use of the IC card. To do.

[0005]

A numerical value input panel used in a card type calculator is mounted on the surface of an IC card.

An IC card has a built-in program function for always controlling output or input of data.

A program for canceling the function of controlling the output or input of the above-mentioned data by inputting the personal identification number on the numeric input panel is incorporated.

A clock function is built in the IC card so that the original input / output control returns to the functional state when the input / output control program for the released data has passed a certain time.

An LED (flashing lamp) is added to the IC card so that when the correct personal identification number is input, this lamp lights up.

The LED (blinking lamp) is turned off when the original input / output control returns to the functional state after a certain period of time.

[0011]

The IC card user cannot use this card without first registering the personal identification number and then entering the predetermined personal identification number.

If the correct personal identification number is entered, the LED (flashing lamp) attached to the card is turned on, and after a certain period of time, the card is returned to the unusable state and the LED is turned off.

[0013]

[Example] When the IC card of the present invention is used, the registered personal identification number is entered on the numeric input panel of the card immediately before use. When the correct PIN is entered,
The LED (flashing lamp) of the card lights up, indicating that the card is currently available for use. The card user confirms that the card is ready for use,
Use a card. After using the card, even if it is left as it is, when the preset time elapses, it will return to a state where it cannot be used unless the password is input again, and at the same time, the LED (flashing lamp) will also turn off and the card cannot be used. Display status. Normally, the usable time will be set to 5 minutes, but depending on the application, it can be set shorter or longer.

[0014]

The IC card of the present invention can be used without inputting a personal identification number, so it is possible to prevent unauthorized use of the card. However, for example, a supermarket cashier cannot use the card. The receiving party can also confirm the lamp indication added to the card indicating that the card can be used, thereby enabling a double fraud prevention function.

Claims (3)

[Claims] 1. A device for inputting a personal identification number is added to an IC card. 2. The IC card according to claim 1, wherein the IC card cannot be used without inputting a personal identification number. 3. An IC having the features of claims 1 and 2 above.
It has a structure that has a built-in program that controls the card so that it can be used only within a certain period of time after inputting a personal identification number. IC card with lamp)
