Description

[Detailed Description of the Invention] [Summary] The purpose is to prevent unauthorized use of a credit card, etc. when it is stolen or lost. This does not require any external equipment.

[Industrial Application Field] The present invention relates to means and devices for preventing unauthorized use of credit cards and the like, and particularly to a fraud prevention card equipped with the means and devices.

[Prior Art] With the recent trend of credit cards becoming more popular, the amount of damage caused by unauthorized use of credit cards and the like is increasing to an enormous amount. surely,
Although there are means to prevent such unauthorized use in the general market, the current reality is that there is no means to effectively prevent it.

That is, as a conventional example, a magnetic tape is attached to a card to prevent unauthorized use at an early stage.

As is well known, this is an online system for inquiring about accident information such as theft and loss.

[Problems to be solved by the invention] However, since this online system requires the installation of extremely expensive terminal equipment, it may not be used in all markets, and prevention of unauthorized use is insufficient. It is. Furthermore, in this conventional example, it is impossible to prevent unauthorized use until the data for information disclosure is input. Furthermore, in the case of credit cards, stores generally have a system in place that allows them to request payment from the credit card company once they have completed a transaction such as buying or selling using the card, so stores are reluctant to guard against unauthorized use. Because they tend to be loose, they also encourage an increase in fraudulent use.

In view of the problems of such engagement, it is an object of the present invention to provide an unauthorized use prevention card that is inexpensive, easy to use, and can prevent unauthorized use without being restricted by space or time. .

[Means for solving problems]

In order to solve the above problems, the present invention houses all the means and devices for preventing unauthorized use in a part of the card body. The means and devices for preventing unauthorized use include a code input key section where the cardholder enters a code such as a code number, a code storage section that stores a desired number known only to the cardholder, and a code manual key section. The cryptographic processing unit includes a cryptographic processing unit that generates a confirmation signal when the input code from the cryptographic processing unit matches the stored code in the code storage unit, a confirmation unit that externally expresses the confirmation signal from the cryptographic processing unit, and a power supply unit.
