Of course, in the above-listed services, such as points earned according to the details used before may also be stored and used together.

For individual services that can be configured in this way, a plurality of service contents may be stored and used in a single integrated smart card, and only a few individual services may be selected and stored and used as integrated service contents. . Of course, it can also be configured to use only a single service.

In the configuration in which a plurality of services are used in one fingerprint recognition smart card 20, a service available by a plurality of contact terminals and a number of connection terminals of one contact terminal 231 are selected. It may be configured to be selected and used.

That is, as an example, in the case of Figures 2, 3 and 6, the individual terminals 233, which are largely divided in the contact terminal 231, is divided into a total of eight, for example, a bank, credit card used as a service Financial services, internet services such as internet portal server, home shopping, internet shopping, resident identity services such as government offices and ward offices, traffic management services such as airports, ships, railways and buses, immigration management services, and employee management services of the company For example, convenience facilities such as hotels, condos, amusement parks, etc. may be used.

In the financial services, the signal connection is made to the second connection terminal (b) and the third connection terminal (c). Therefore, the fingerprint recognition smart card 20 is connected to the second connection terminal (b) and the third connection terminal (c). In the case of signal connection, it may be provided for processing related to financial services. That is, when data signals are transmitted to the second connection terminal (b) and the third connection terminal (c), the input / output unit 24 determines that the information is related to the "financial service", and the input / output unit 24 determines the "financial". Service ", the signal data transmitted from the card reader 30 and the input / output unique ID of the input / output unit 24 may be configured to be transmitted to the central processing unit 22 side.

Therefore, the central processing unit 22 receiving such a signal determines that the transmitted signal is information related to the "financial service", so that the response signal sent back to the card reader 30 is transmitted so that the information related to the financial service is transmitted. It can be constructed. In the central memory unit 224, the financial service memory unit may be separately configured to store information related to the "financial service".

In connection with the above financial service, it is illustrated that the second connection terminal (b) and the third connection terminal (c) of the input / output unit 24 are configured to use. In the case of the Internet service, the fourth connection terminal (d) and the sixth connection are used. This may be the case when the access terminal f is connected and configured to transmit a signal, and in the case of the resident identity service, the case where the access terminal 7 and the access terminal 8 are connected and transmitted. It may be configured to.

Furthermore, as described above, two connection terminals may be interconnected and signaled, or may be connected to signal transmission through three or more connection terminals. In other words, the traffic management service is connected to the second access terminal (b), the third access terminal (c) and the fourth access terminal (d), the immigration management service is the second access terminal (b), the third access terminal (c) and the sixth connection terminal (f) is connected, the staff management service is connected to the third connection terminal (c), the sixth connection terminal (f) and the seventh connection terminal (g), In addition, the convenience facility using service may be configured to transmit data according to a corresponding service when the sixth access terminal (f), the seventh connection terminal (g), and the eighth connection terminal (h) are connected.

Examples of such connection terminals have been described in any way set forth in order to effectively explain the present invention, the present invention is not limited to this, it is natural that can be properly set and used according to the installation situation.

Therefore, when the card reader 30 and the connection-type terminal 231 are connected to each other to determine the services that can be used as a terminal for signal connection with each other, the central processing unit transmits a signal transmitted from the card reader 30. In (22), it is not necessary to separately classify and determine which service data. Therefore, it is possible to simplify the processing processor for determining which service, so that there is an advantage of immediately processing the data.

In addition, since the card reader 30 does not have to worry about receiving data of a service other than the data of the corresponding service, it is possible to use a safe and accurate service.

In particular, when distinguishing that the signal connection is made by using a plurality of connection terminals, the data of the service is transmitted by matching the connection terminal of the smart card and the connection terminal of the card reader of the service with respect to the information of the user. Therefore, with respect to the card reader and the smart card used as another connection terminal, there is an advantage that does not need to separately distinguish between the normal card reader and the normal smart card, there is an advantage such that the reliability of the transmitted data is improved accordingly. .

Looking at the control method of the fingerprint recognition smart card system (A) according to the present invention configured as described above are as follows.

4 and 5, when the user 10 connects the fingerprint recognition smart card 20 to the card reader 30, the card reader 30 detects the connection of the fingerprint recognition smart card 20. do.

When the user displays a desired menu on the display panel of the host unit 40 or the card reader 30 and selects a corresponding menu, the host unit 40 or the server of the menu displays information about the user 10. You will be asked.

Therefore, the request signal transmitted from the server or host unit 40 is transmitted to the fingerprint recognition smart card 20 through the card reader 30, the card reader 30 is a response signal from the fingerprint recognition smart card 20 The signal is switched to the standby state for receiving the signal.

The fingerprint recognition smart card 20 receives the information call request signal from the card reader 30 at the interface unit 23 of the input / output unit 24 and stores it in the input / output memory unit 242. The receiving step S11 is performed. Of course, if the card reader 30 and the fingerprint recognition smart card 20 are signaled to each other, the signal is received through the contact terminal 231, and in the case of the non-contact, the signal is received through the non-contact antenna 232. It may be provided to be.

In addition, an input / output side signal sending step S12 of adding the input / output unique ID data of the input / output unit 24 to the information processing request signal data transmitted from the card reader 30 and transmitting the same to the central processing unit 22 is performed. The input / output unit 24 enters a reception standby state with respect to the signal to be transmitted from the central processing unit 22 side.

Accordingly, the central processing unit 22 receives and stores the data transmitted from the input / output unit 24, and determines whether the input / output unique ID included in the received data matches the input / output unique ID stored in the central memory unit 224. The reception I / O ID determination step S13 is performed.

When the received I / O unique ID is determined to be a normal I / O unique ID, the central processing unit 22 adds the central unique ID data together with the user authentication request data (user information request signal) to the user sensing unit 21 and transmits the sum. Authentication request signal transmission step (S14) is performed.

However, when the input / output unique ID of the data transmitted from the input / output unit 24 and the input / output unique ID stored in the central processing unit 22 do not match, the fingerprint recognition smart card (see FIG. 20 is to transmit information about the damage. Of course, the information about the error signal is stored in the central memory unit 224.

When the input / output unique ID is normal and requests user fingerprint information for normal user authentication, the user sensing unit 21 receives and stores data transmitted from the central processing unit 22 and includes the received data in the received data. The sensing-side central unique ID discrimination step S15 of determining whether the central unique ID and the central unique ID stored in the sensing memory unit 213 match is performed.

In the user sensing unit 21, when the central unique ID is determined to be normal, the fingerprint sensing step of storing information on the fingerprint of the user input from the user fingerprint sensor 212 in the sensing memory unit 213 ( S16) is performed.

However, when the central unique ID of the data transmitted from the central processing unit 22 and the stored central unique ID do not normally match, information on the damage of the fingerprint recognition smart card 20 is transmitted to the card reader 30.

In the user sensing unit 21, the fingerprint data transmitting step S17 of adding the data of the sensing unique ID of the user sensing unit 21 together with the data of the sensed user fingerprint and transmitting the data to the central processing unit 22 side is performed. It is done.

Accordingly, the central processing unit 22 receives and stores data transmitted from the user sensing unit 21 and whether the sensing unique ID included in the received data and the sensing unique ID stored in the central memory unit 224 match. The sensing unique ID discrimination step (S18) for determining is performed.

In addition, when the sensing unique ID is determined to be normal in the central processing unit 22, the fingerprint data of the user transmitted from the user sensing unit 21 and the fingerprint data of the user stored in the central memory unit 224 are determined to be normal. A user fingerprint discrimination step S19 of determining whether a user is performed is performed.

Of course, when the fingerprint of the sensed user is determined as the fingerprint of the normal user, the central processing unit 22 determines the information call request signal transmitted from the card reader 30 and stores the corresponding information stored in the central memory unit 224. The storage information sending step (S20) of adding the data information and the central unique ID and transmitting the same to the input / output unit 24 is performed.

However, when the sensing unique ID of the data transmitted from the user sensing unit 21 and the stored sensing unique ID do not normally match, information on the damage of the fingerprint recognition smart card 20 is transmitted to the card reader 30. .

The input / output unit 24 receives and stores data transmitted from the central processing unit 22, and determines whether the central unique ID included in the received data matches the central unique ID stored in the input / output memory unit 242. The central I / O side identification step S21 is performed.

When the central unique ID is determined to be normal in the input / output unit 24, a request for transmitting the stored data information transmitted from the central processing unit 22 to the card reader 30 through the interface unit 23. The data sending step (S22) is performed.

However, if the central unique ID of the data transmitted from the central processing unit 22 and the stored central unique ID do not match, it is also determined that the fingerprint recognition smart card 20 is damaged and transmits the information about this to the card reader 30. Will be.

As described above, the input / output unique ID stored in the input / output unit 24, the central unique ID stored in the central processing unit 22, and the sensing unique ID stored in the user sensing unit 21 are fingerprint recognition smart cards 20 according to the present invention. ) May be configured to be stored in each memory unit in a manufactured state.

When the input / output unit 24, the central processing unit 22, the user sensing unit 21, and the like, which are individual modules, are manufactured separately, each memory unit, preferably a drive program, is stored in each ROM. After being stored, the input / output unit 24, the central processing unit 22, the user sensing unit 21, and the like may be combined to form a single card, which is one fingerprint recognition smart card 20.

In particular, in the examples listed above, the important point is that the input / output unit 24, the central processing unit 22, the user sensing unit 21, etc., each unique ID is preferably configured so that it is not changed after being stored, In the case where different input / output devices, sensing devices, or processing units are combined and used in the future, it is preferable that an error occurs when the unique IDs of the mutual inputs are different. This means that when the fingerprint recognition smart card 20 according to the present invention is used incorrectly due to loss or theft, even if it attempts to read the stored information by a separate input / output device, processing and sensor, if the corresponding unique ID is different, information transmission is performed. There is an advantage to prevent the leakage of the user information.

In addition, even when the fingerprint recognition smart card 20 is not damaged, when the corresponding card reader 30 is not correct for each service, the individual connection terminals of the contact terminal 231 are different when the connection interface unit 23 is used. If the card reader 30 is connected, the card reader 30 or the fingerprint recognition smart card may be configured to be determined to be abnormal.

Further, the receiving side information request signal receiving step (S11) to request data transmitting step (S22), etc., relates to an embodiment of a control method according to signal input / output of the fingerprint recognition smart card 20 according to the present invention. The data stored in accordance with the signal requested from the individual server or the host unit 40 for the financial service, Internet service, identity service, traffic management service, immigration service, staff management service, and convenience facility use service, etc. It may be configured to be signaled by the method. In addition, the receiving side information request signal receiving step (S11) to the request data sending step (S22) and the like described an embodiment of the preferred control method of the fingerprint recognition smart card 20, depending on the installation environment Of course, it is possible to change.

In the case of the bank's financial services, when the fingerprint recognition smart card 20 is inserted into a card reader, such as an ATM, the card reader 30 may be used. In response, the display unit of the corresponding terminal displays a menu desired by the user.

When the withdrawal of the deposit amount is selected, the terminal requests the fingerprint recognition smart card 20 for user basic information about the user's account information and password. Thereafter, an information request signal is transmitted to the input / output unit 24 and the central processing unit 22 of the fingerprint recognition smart card 20, and a request signal for fingerprint recognition is transmitted to the user sensing unit 21.

In addition, the central processing unit 22 displays a notification message for fingerprint recognition sensing on the display unit of the terminal through the input / output unit 24 side, so that the user fingerprints the user sensing unit 21 of the fingerprint recognition smart card 20. Will be made scanable. Of course, it is preferable that the user sensing unit 21 senses whether the user's body temperature, human body current, etc. are sensed together with the fingerprint sensing, and whether the fingerprint is recognized by the normal user.

Then, if it is determined by the fingerprint recognition of the normal user, the user's account information, account password or account authentication code stored in the bank financial service storage unit (not shown) of the central memory unit 224 through the input and output unit 24 It may be configured to be transmitted to the terminal and the bank server.

Accordingly, the bank server determines whether the corresponding user is a normal user or a normal account and displays a response signal on the display unit of the terminal.

In addition, the bank server or the terminal may be configured to indicate what service the user wants for the account, and the user selects the withdrawal. Since information about this is transmitted to the bank server, the bank balance may be stored in the bank server. In addition, the balance of the account may be stored in the user's fingerprint recognition smart card 20 as well as the bank server.

Therefore, when the withdrawal processing of the bank server is configured to withdraw and withdraw only to the fingerprint recognition smart card, it may be configured to be recognized as a normal user only when the balance information stored on the fingerprint recognition smart card and the information of the balance stored on the bank server match. It is.

However, if deposit and withdrawal is possible in various ways such as internet banking and telebanking, the balance information stored in the bank server may be simply configured to be stored in the fingerprint recognition smart card.

As such, the account balance information stored in the bank server or the fingerprint recognition smart card may be provided to be displayed on the display unit of the terminal, and the user may input the desired amount to be withdrawn. Of course, the balance information may be configured to be stored only in the memory of the terminal when the balance is not displayed on the terminal display unit.

When the withdrawal amount input by the user is greater than the balance amount, a message indicating a balance is displayed. And if the normal withdrawal amount may be configured to request a fingerprint authentication request to the fingerprint recognition smart card 20 side for the user approval for withdrawal. Accordingly, as described above, the authentication process may be configured to be a withdrawal approval when data is transmitted and determined as a normal user.

When such a series of processes is completed, a request signal for withdrawal is transmitted to the bank server, and the bank server transmits information on withdrawal approval to the terminal, and the terminal withdraws the withdrawal amount desired by the user. In addition, the bank server stores the balance information, excluding the withdrawal amount, from the already stored balance in the bank server, and transmits the information of the corresponding balance to the terminal. Thereafter, the terminal may be configured to transmit and store information of the corresponding balance to the fingerprint recognition smart card 20 through the card reader 30.

The above shows an embodiment of a financial service related to a bank, but is not limited thereto and may be configured to withdraw and withdraw from a bank by various methods. In addition, it is a matter of course that the control method through the fingerprint recognition smart card 20 such as a shopping mall may be applied to banking services such as bank transfer of bills and payment of utility bills.

And personal information such as the user's address, social security number, family relationship, blood type, such as identity services can be stored and used in the fingerprint recognition smart card (20).

Accordingly, when the fingerprint recognition smart card 20 is connected to a terminal that is a card reader 30 installed in an office, a ward office, an airport, or an entrance of a building, information requested by the corresponding terminal is transmitted from the fingerprint recognition smart card 20. It is used. The newly updated information, such as the address transfer, is stored in the address memory unit (not shown) of the central memory unit 224 of the fingerprint recognition smart card 20 as new information. The old information may be provided to be stored in a separate central memory unit 224.

The central memory unit 224 may be configured with a data memory unit such as an address that can be changed at any time, and a data memory unit that does not always change, such as a user's social security number.

In the case of using a convenient facility such as a hotel, a condo, an amusement park, or a restaurant, a unique code value such as a subscription unique number and an access password for the relevant facility may be stored in a fingerprint recognition smart card. Accumulated points, etc. may be stored together and configured to be available at any time.

In particular, in the case of using the respective convenience facilities for the integration point that each convenience facilities can be integrated with each other, the cumulative points according to the use can be configured to be stored separately and integrated at the time of use, When used, regardless of which facilities have been accumulated, it may be configured to use the integrated points stored as integrated.

Therefore, there is an advantage to use a variety of information by the information on the integrated point stored in the fingerprint recognition smart card 20 according to the present invention.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art without departing from the spirit and scope of the invention described in the claims below In the present invention can be carried out by various modifications or variations.
