In the embodiment of the present invention, if necessary, the power supply device 250 may be provided with a power switch to supply power only when necessary.

Referring to FIG. 5, first, when a user places a fingerprint of a finger on a corresponding area of the fingerprint input recognition module 120, the fingerprint recognition module 120 recognizes a fingerprint and uses the biometric authentication control unit 111 through the module controller 112. In step S502, the biometric authentication unit 111 compares the input fingerprint with the fingerprint stored in the memory 130 (S504).

When the input fingerprint and the fingerprint stored in the memory 130 match, the biometric controller 111 determines whether the USB connector 150 is connected through the USB controller 140. In addition, a signal is applied to the RF switch unit 220 to make it operable.

In the process, the user connects the USB connector 150 to the USB port 450 of the computer 400 as necessary.

A screen for asking whether to use or use the USB function is displayed (S505).

On the other hand, if the fingerprint is inconsistent, the authentication mismatch is simply displayed on the display unit 190 and the authentication process is performed again.

Thereafter, when the user selects a menu, the controller 420 determines what the selected menu is (S506).

If the selected menu is a USB function, the controller 420 performs a process of storing or reading the corresponding information in the memory 130 through the USB connector 150 and the USB controller 140 according to an operation of the input unit 470. The multi-access device according to an embodiment of the present invention serves as a USB memory (S507).

On the other hand, if the selected menu is a one-time password function, the control unit 420 displays on the monitor 450 to open the cap 102 (S508).

Thereafter, when the user opens the cap 102 or opens the cap and presses the open / close switch 231 (S509), the open / close detection unit 170 or the open / close switch 231 opens the cap 102 so that the OTP control unit 160 opens. To tell.

Then, the OTP control unit 160 generates a key value according to a predetermined key generation algorithm and transmits the key value to the control unit 420 through the USB connector 150, and the control unit 420 transmits the key value to the monitor 430 or the display unit 190. (S511).

Thereafter, according to the user's needs, a financial transaction is performed by accessing an external bank server 330 or another financial institution server through the network 500. That is, the user performs a desired task using the one-time password displayed on the monitor 430 or the display 190.

In the process (S520), when the USB connector 150 is not connected, a menu is selected from the user (S521). That is, it receives a switch selection.

Then, the switch unit 220 determines whether the user has selected the car key or the door lock key (S523).

If the car key is selected, the switch unit 220 generates a signal by applying the power of the power supply device 250 to the car key signal generator 230. Then, the high frequency signal having the corresponding frequency is transmitted to the receiving unit (not shown) of the vehicle to open and close the door (S524).

On the other hand, if the door lock is selected, the switch unit 220 generates a signal by applying the power of the power supply device 250 to the door lock opening and closing signal generator 240. Then, a high frequency signal having the corresponding frequency is transmitted to the receiver (not shown) of the door lock to open and close the door (S525).

In the above process, in addition to the high frequency, other frequencies or infrared signals may be used, and this process may be variously modified as necessary.

The following describes a case where the multi-access device is used alone.

The recognition module 120 recognizes a fingerprint (S620) and transmits the fingerprint to the biometric authentication control unit 111 through the module controller 112, and the biometric authentication control unit 111 stores the input fingerprint and the fingerprint stored in the memory 130. Compare (S640).

When the biometric authentication control unit 111 matches the input fingerprint and the fingerprint stored in the memory 130, authentication is completed (S640), or even when the fingerprint is inconsistent, the authentication mismatch is displayed on the display unit 190 (S630). When the authentication is completed by performing the process again, the OTP controller 160 determines whether there is a selection of the RF switch unit 220.

If there is no switch selection, a key value is generated according to a predetermined key generation algorithm and displayed on the display unit 190 (S660).

Thereafter, the user performs a desired task using the one-time password displayed on the display 190.

The work here involves financial transactions or other tasks such as internet banking that require authentication.
