Abstract
The present invention relates to a fingerprint sensor, comprising: a sensor unit having a fingerprint recognition sensor formed on one surface thereof and formed to be bent when a user touches the sensor; a piezoelectric element arranged to overlap the sensor unit and generating electrical energy corresponding to the banding; And a power supply unit spaced apart from the piezoelectric elements and electrically connected to the piezoelectric element and the power supply unit during the bending operation to supply the generated electrical energy.
Description
The present invention relates to a fingerprint recognition card based on NFC communication and a payment method using the same.
Fingerprints are considered to be an important element to identify a person because of the fact that people have different fingerprints and that they do not change forever as they were when they were born.
According to the recent research, when the fingerprint is used as the authentication means, the problem of trespassing is least generated compared to other authentication means, the authentication means rarely causes an accident that is stolen, Which is significantly smaller than the authentication means.
In the conventional card, a user inputs a password of a card to an ATM or inputs a card unique number and an expiration date to authenticate the user. To use such a conventional card requires an expensive large-capacity host computer, and if the card is duplicated, lost, or the password of the card is exposed, the owner of the card would be economically damaged.
The fingerprint recognition card is a system that complements the data storage function, which is a disadvantage of existing credit card or debit card, and combines the advantages of IC (Integrated Circuit) card with the advantages of fingerprint security system. In order to solve the problems of the prior art, a payment system using such a fingerprint recognition card is being studied.
It is an object of the present invention to provide an authentication method using a fingerprint recognition card and a fingerprint recognition card based on NFC communication.
The object of the present invention is to provide a fingerprint sensor which is formed on one side of a fingerprint sensor and which is formed to be bent when a user touches the sensor, And a power supply unit disposed so as to face the piezoelectric elements and facing each other, wherein the piezoelectric device and the power supply unit are electrically connected to each other so as to supply the generated electric energy. Can be achieved.
According to a preferred aspect of the present invention, the power supply unit includes an embedded battery, and the sensor unit and the built-in battery are electrically connected when bending.
According to another preferred aspect of the present invention, there is further provided a communication unit including an NFC module, wherein the communication unit is formed to be electrically connected to the power supply unit during the bending operation.
According to another aspect of the present invention, there is provided a method for authenticating a user, comprising: a sensor unit for recognizing a user fingerprint; a control unit for generating a unique identification value corresponding to the recognized fingerprint; a memory unit for storing the unique identification value; And transmitting the data related to the unique identification value to the adjacent terminal so that the fingerprint identification card can recognize the unique identification value.
According to another aspect of the present invention, there is provided a method of manufacturing a fingerprint sensor, comprising the steps of: (a) applying pressure to a fingerprint sensor by a user's touch; (b) (C) electrically connecting the piezoelectric element and the power supply unit by the banding to supply power to the fingerprint recognition sensor; and (d) recognizing the fingerprint of the user by the fingerprint recognition sensor. And can be achieved by providing an authentication method using a fingerprint recognition card.
According to a preferred aspect of the present invention, a unique identification value corresponding to the recognized fingerprint is generated and stored in the memory of the fingerprint recognition card.
According to another preferred aspect of the present invention, the generation of the unique identification value is performed by an identification value generation command of an adjacent terminal.
According to another preferred aspect of the present invention, when the fingerprint of the recognized user corresponds to the stored unique identification value, the communication unit is activated and transmits information on the unique identification value to an adjacent terminal.
The fingerprint recognition card according to the present invention can increase the life of the card by allowing the fingerprint recognition sensor, the piezoelectric element and the switch to be combined with each other to efficiently use the electric energy generated when the user recognizes the fingerprint.
In addition, the authentication method using a fingerprint recognition card according to the present invention does not transmit user information to a server during user registration, but stores a unique identification value corresponding to a user's fingerprint on a card. Accordingly, leakage of personal information can be prevented, and user authentication can be performed more easily when using a card.
