The human body temperature and blood flow can be distinguished, but when the temperature is recognized, if one's blood flows through one sensor, the temperature of the human body is automatically recognized as normal and can be processed.

Thereafter, the card controller 1501 receiving the fingerprint data of the finger compares the fingerprint data of the user stored in the card memory unit 1503 and matches the card information with the tag unit 1506 through the data output unit 1505. The tag 1506a and the IC chip 1506b are recorded in at least one so that the authentication card 1500 can be used for payment.

At this time, if the card information is normally recorded on the tag unit 1506 through the display unit 1504, the user can display the display unit 1504 to check the normal use state of the authentication card 1500.

Here, the card controller 1501 may compare the input fingerprint mac data with the user's fingerprint stored in the card memory unit 1503.

Is a perspective view.

As shown in FIGS. 12 to 14, the decompression power sensor 1509 is formed on the back side of the fingerprint authentication module 1600 as a finger receiving unit as a power supply unit 1507 for generating and storing power for the operation of the authentication card 1500. .

The fingerprint authentication module 1600 is configured to form a groove 1500a at one side of the handle of the authentication card 1500 so as to be easily seated.

As shown in Figure 12 (a), the fingerprint authentication module 1600 has a multi-layer thin plate structure, the fingerprint registration layer 1620 is formed on the lower layer of the fingerprint authentication module 1600, the fingerprint recognition layer on the upper layer 1610 is formed, the fingerprint (1600a) is registered in the lower portion is divided into a layer that the user can read and read when authentication, where the fingerprint recognition layer 1610 is formed as an upper layer, the lower portion Temperature and blood flow detection authentication layer 1611 is formed to detect the temperature and blood flow of the human body is formed to start its operation.

The sensing authentication layer 1611 is formed of a semiconductor device, but when the human body temperature is not human or there is no flow of blood, the sensing authentication layer 1611 is a technology that does not operate or authenticate.

As shown in Figure 12 (b), the fingerprint authentication module 1600 has a multi-layer thin plate structure, the fingerprint registration layer 1620 is formed on the lower layer of the fingerprint authentication module 1600, the fingerprint recognition layer on the upper layer 1610 is formed, and the fingerprint 1600a is registered at the lower portion thereof and is divided into a layer that the user can read and read when authenticating, wherein the fingerprint recognition layer 1610 is formed as an upper layer, and the surface thereof. Temperature and blood flow sensor 1522 (hereinafter, referred to as the "biometric recognition unit" with the detection authentication layer) is formed to detect the temperature and blood flow of the human body is formed to start its operation.

Fig. 13 is a perspective view of the fusion authentication card according to Fig. 12B of the present invention, showing a position where a finger should be held, and showing the shape of a fingerprint on the top thereof.

As shown in FIG. 14, the reduced pressure power sensor 1509 is formed by stacking a polymer conductor film on a sheet of thin film, and alternately arranging the negative electrode and the positive electrode in the shape of a comb on the sheet of another film facing the plate. The pressure-sensitive resistance variable sensor element formed of carbon powder and tungsten oxide powder is stacked on the surface, and when pressed against the polymer conductor film, the resistance change in pressure can be detected and transmitted as an electrical signal. .

As shown in Fig. 14 (a) and (b), a polymer conductor film 2 is laminated on the substrate 1 of one non-conductor film, and a polymer conductor film is matrixed on the substrate 1 'of the other non-conductor film. The pressure sensor was formed by forming an electrode 2 'and stacking a pressure-sensitive resistance variable pressure sensor element 3 in which carbon powder and tungsten oxide powder were mixed and laminated on the upper surface thereof with a synthetic resin binder.

In another embodiment, as shown in Fig. 14 (c), a carbon powder and a tungsten oxide powder are formed on one earth 1 'and the other earth 1 on which the polymer conductor matrix electrode 2' is formed. The pressure-sensitive-resistance variable pressure sensor 3 (3 ') mixed and laminated with a bonding agent may be laminated.

Therefore, the decompression power sensor 1509 is formed on a portion that is naturally pressurized when the card is held to recognize a fingerprint, and thus is easily used, and is treated as a permanent material that can generate power at all times. Therefore, it is adopted as a power source for fingerprint recognition.

In addition, the fingerprint authentication module, which is a finger receiving unit, is provided with a temperature or / and blood flow sensor 1522 to detect the temperature of the finger and / or the flow of blood when the finger is in contact with the power controller 1507 after activating the card controller 1501. The scan unit 1502 may be operated through a power source.

This effect is as described above.

The card controller 1501 transmits and records a signal recorded in the tag unit 1506, that is, card information when the fingerprint data input from the scan unit 1502a and the fingerprint data stored in the card memory unit 1503 match. After using the card information by touching it twice, it is preferable to initialize the tag unit 1506 so that the card information is lost.

Alternatively, the card controller 1501 writes the card information to the tag unit 1506, and then holds the tag unit 1506 for a set time, e.g., 5 seconds for card approval. It is also desirable to initialize so that the card information is lost.

As an external configuration of the authentication card 1500, as shown in FIG. 13, the IC chip 1506b and the power supply unit 1507 of the IC chip 1506b and the power supply unit 1507 are provided on the front surface of the authentication card 1500 as a tag unit 1506. In addition, the fingerprint authentication module 1600 is formed, the NFC tag 1506a may be formed as a tag unit 1506 on the back.

The fingerprint authentication module 1600 is a multi-layered thin plate structure, the fingerprint registration layer 1620 is formed on the lower layer of the fingerprint authentication module 1600, the fingerprint recognition layer 1610 is formed on the upper layer, The fingerprint 1600a is registered in the lower portion thereof, and is divided into layers in which the user can read and read it when authenticating, and it is a useful technology that can serve as a security card by using them.

As described above, according to the fusion authentication card using the fingerprint recognition according to an embodiment of the present invention, if the data of the fingerprint is mounted on the authentication card itself, and the user's fingerprint is read and read from the card itself, it may be used. It is effective to increase the security and reliability of the card user's authenticity verification in performing tasks such as cash withdrawal or card payment, and can significantly improve the false recognition rate of fingerprints when double security is required. By simultaneously authenticating the fingerprint and the blood flow sensor associated with it, it reduces the false recognition rate due to the forgery of the fingerprint, and easily recognizes the human body information of the fingerprint with just one finger. There is an effect that can be exerted.

15 is a flowchart illustrating a processing method of a fusion authentication card according to an embodiment of the present invention.

As shown in FIG. 15, for the processing of the fusion authentication card according to the embodiment of the present invention, first, a finger is placed on the finger receiving unit 1523 to detect a blood flow state of the finger (S1500).

In order to detect the blood flow of the finger in the present embodiment, when the blood flow of the finger is detected through the blood flow sensor 1522 of the scan unit 1502 formed in the finger receiving unit 1523, the card controller 1501 is connected through the bioelectric. Activate it.

If the blood flow of the finger is not detected at step S1500, the card controller 1501 is not activated and continues to stand by.

On the other hand, when the blood flow of the finger is detected in step S1500 and the card controller 1501 is activated, the card controller 1501 operates the fingerprint scan unit 1520 of the scanning unit 1502 to irradiate the finger with the visible line of the visible light source unit 1520a. Or contact the fingerprint to the fingerprint authentication module (S1510).

In operation S1510, the fingerprint data is input by scanning the fingerprint of the finger through the fingerprint image sensor 1520b or the fingerprint authentication layer while irradiating a finger with a visible line or contacting the fingerprint with the fingerprint authentication module.

After receiving the fingerprint data input from the user's finger in step S1520, the card controller 1501 compares the fingerprint data stored in the card memory unit 1503 and determines whether there is a match (S1530).

Here, the card controller 1501 compares the input fingerprint data with the fingerprint data of the user stored in the card memory unit 1503.

When the scan information of the user's finger scan and the information stored in the card memory unit 1503 match in operation S1530, the card controller 1501 outputs card information through the data output unit 1505 to display the tag unit 1506. Card information is recorded in at least one of the NFC tag 1506a and the IC chip 1506b (S1540).

In addition, when the card information is normally recorded in the tag unit 1506, the card controller 1501 operates the display unit 1504 to allow the user to recognize that the authentication card can be normally used (S1550).

In the state in which the use of the authentication card 1500 is enabled in step S1550, the authentication card 1500 may be provided to another person for payment such as a cashier. After enabling the use of the authentication card 1500 as described above, the card controller 1501 compares whether the set time has elapsed (S1560).

When the set time elapses in step S1560, for example, when 5 seconds elapses, the card controller 1501 initializes the tag unit 1506 to lose card information recorded in the NFC tag 1506a and the IC chip 1506b. By doing so, it is impossible to use the authentication card 1500.

In this case, when the card controller 1501 uses the card information by touching the authentication card 1500 once, the card controller 1501 may initialize the tag unit 1506 to cause the card information to be lost.

In this way, after the card controller 1501 initializes the tag unit 1506, the operation of the display unit 1504 may be stopped to allow the user to recognize a state in which the authentication card 1500 is unavailable.

The following describes an invention in which two authentication modules are installed in an authentication card.

FIG. 16 is a block diagram showing a main configuration of a fusion authentication card according to another embodiment of the present invention, and FIG. 17 is a configuration diagram specifically illustrating a scan unit of a fusion authentication card according to another embodiment of the present invention. 18 is a schematic perspective view of an authentication card showing a state where a module is installed, and FIG. 18 is a flowchart illustrating a method of processing a fusion authentication card according to an embodiment of the present invention.

8 is the same as the block diagram in FIG. 8, but the fingerprint scan unit 1521 is formed in addition to the fingerprint cap unit 1520.

As shown in FIG. 16, the authentication card 1500 includes two fingerprint scan units 1520 and 1521 for generating and outputting fingerprint data by a human finger, and blood flow of a finger of a customer generated when the finger is in contact. A scan unit 1502 including a blood flow sensor 1522 for activating the card controller 1501 through a blood stream that recognizes a flow is formed, and the fingerprint memory unit 1503 reads fingerprint data from the scan unit 1502. The card controller 1501 determines whether the card data is matched with the fingerprint data for authenticity verification stored in the tag, and the tag unit 1506 such as the NFC tag 1506a or the IC chip 1506b receives a signal output from the card controller 1501. A data output unit 1505 is recorded on the display unit, and a display unit 1504 indicating whether or not its operation is performed is formed.

Here, the fingerprint data stored in the card memory unit 1503 stores fingerprint data acquired by scanning a fingerprint through a scanning device (not shown) provided separately at a financial institution and a card issuing institution when issuing the authentication card 1500. Can be.

In addition, a solar cell panel 1507a or a reduced pressure power sensor 1509 is formed on the front surface of the authentication card 1500 as a power source 1507 that generates and stores power for operation of the authentication card 1500.

The card controller 1501 transmits and records a signal recorded in the tag unit 1506, that is, card information when the fingerprint data input from the scan unit 1502 and the fingerprint data stored in the card memory unit 1503 match. After using the card information by touching it twice, it is preferable to initialize the tag unit 1506 so that the card information is lost.

Alternatively, the card controller 1501 writes the card information to the tag unit 1506, and then holds the tag unit 1506 for a set time, e.g., 5 seconds for card approval. It is also desirable to initialize so that the card information is lost.

As shown in Fig. 17, Fig. 17 is a perspective view of the fusion authentication card of the present invention, which shows a position where two fingers must be held, and shows the shape of a fingerprint on the top thereof.

The reduced pressure power sensor 1509 used here is formed by stacking a polymer conductor film on a sheet of thin film, and alternately arranging the negative electrode and the positive electrode in the shape of a comb on the sheet of another film facing the plate, and carbon powder on the surface thereof. And a pressure-sensitive resistance variable sensor element formed of a tungsten (TUNGSTEN) oxidized powder is stacked to press the polymer conductor film to detect a change in resistance to pressure and to transmit it as an electrical signal.

As shown in FIG. 18, FIG. 18 is a flowchart illustrating a method of processing a fusion authentication card according to an embodiment of the present invention.

In order to process the fusion authentication card according to an embodiment of the present invention, first, a finger is placed on the finger receiving unit 1523 to detect a blood flow state of the finger (S1500).

In order to detect the blood flow of the finger in the present embodiment, when the blood flow of the finger is detected through the blood flow sensor 1522 of the scan unit 1502 formed in the finger receiving unit 1523, the card controller 1501 is connected through the bioelectric. Activate it.

If the blood flow of the finger is not detected at step S1500, the card controller 1501 is not activated and continues to stand by.

On the other hand, when the blood flow of the finger is detected in step S1500 and the card controller 1501 is activated, the card controller 1501 operates the fingerprint scan units 1520 and 1521 corresponding to the fingerprints 1 and 2 of the scan unit 1502. The fingerprint is contacted with the authentication module 1600a or 1600b (S1510).

In operation S1510, the fingerprint contact module receives the fingerprint data by scanning the fingerprint of the finger through each fingerprint image sensor while contacting the fingerprint with the fingerprint authentication modules 1600a and 1600b.

After receiving the fingerprint data input from the user's finger in step S1520, the card controller 1501 compares the fingerprint data stored in the card memory unit 1503 and determines whether there is a match (S1530).

Here, the card controller 1501 compares the input fingerprint data with the fingerprint data of the user stored in the card memory unit 1503.

If the scan information of the user's finger scan and the fingerprint 1 information stored in the card memory unit 1503 match in step S1530, authentication processing is performed, and in step S1535, the scan information of the user's finger scan and the card memory unit 1503 are scanned. When the stored fingerprint 2 information is matched, the card controller 1501 outputs the card information through the data output unit 1505 so that the card controller 1501 at least one of the NFC tag 1506a and the IC chip 1506b of the tag unit 1506. Information is recorded (S1540).

In addition, when the card information is normally recorded in the tag unit 1506, the card controller 1501 operates the display unit 1504 to allow the user to recognize that the authentication card can be normally used (S1550).

In the state in which the use of the authentication card 1500 is enabled in step S1550, the authentication card 1500 may be provided to another person for payment such as a cashier. After enabling the use of the authentication card 1500 as described above, the card controller 1501 compares whether the set time has elapsed (S1560).

When the set time elapses in step S1560, for example, when 5 seconds elapses, the card controller 1501 initializes the tag unit 1506 to lose card information recorded in the NFC tag 1506a and the IC chip 1506b. By doing so, it is impossible to use the authentication card 1500.

In this case, when the card controller 1501 uses the card information by touching the authentication card 1500 once, the card controller 1501 may initialize the tag unit 1506 to cause the card information to be lost.

In this way, after the card controller 1501 initializes the tag unit 1506, the operation of the display unit 1504 may be stopped to allow the user to recognize a state in which the authentication card 1500 is unavailable.

When the authentication card is manufactured using the two modules as described above, an error may occur in the degree of fingerprint recognition in the manufacturing process, and when one attempts to reduce the probability of fingerprint imitation using only one, If you encounter high difficulty, and if the angle of adhesion is different at the time of authentication, not only the recognition will be lowered, but also if you design 100% match, it may be difficult to recognize part of your finger due to water or ink. Therefore, when the matching of the fingerprints is lowered to about 60% and the two fingerprints are simultaneously authenticated to enable the operation of the card, the design of the mechanical recognition technology is rather easy and the state of imitation or the same probability is almost eliminated. Invented to be.

That is, if the error probability of one fingerprint is one hundredth of 100,000, if it is lowered to 80% recognition rate, and if two conditions are used to satisfy simultaneously, it becomes one-half of 6.4 billion corresponding to the square of 1 / 80,000. The results show that this is a probability of covering the Earth's population, leading to the conclusion that no two identical fingerprints can be realistically present.

In addition, when grounding with two fingers, the structure of the fingerprint recognition can be stably and consistently grounded, thereby increasing the recognition.

As described above, according to the processing method of the fusion authentication card using the fingerprint recognition according to the embodiment of the present invention, unless the fingerprint data is loaded on the authentication card itself and the user's fingerprint is read and read from the card itself. In addition, it is effective to increase the security and reliability of the card user's authenticity verification in performing tasks such as cash withdrawal or card payment by disabling it.In case of double security, the false recognition rate of fingerprint is remarkably increased. By using a blood flow sensor that can be improved, it reduces the false recognition rate of the fingerprint and easily recognizes the human body information of the fingerprint with just one finger, which has the effect of creating a security effect that can replace the certificate. have.

The following describes another embodiment.

19 is a block diagram of an authentication card, and FIG. 20 is an authentication card in which an identification picture is expressed, which is an embodiment of the present invention. FIGS. 21 and 22 are registration steps of an authentication card in which an authentication picture is expressed, which is an embodiment of the present invention. The processing procedure of the authentication step.

As shown in FIG. 19, the authentication card 1500 includes a fingerprint scan unit 1520 for generating and outputting fingerprint data by a human finger, and a photo scan unit 1521aa for generating and outputting an ID photo by scanning an ID photo. And a scan unit 1502 including a basic information input unit 1522bb for inputting certain basic information to generate and output basic information, and reads fingerprint data from the scan unit 1502 to the card memory unit 1503. The card controller 1501 which determines whether the fingerprint data for authenticity checking is stored and the signal output from the card controller 1501 are sent to a tag unit 1506 such as an NFC tag 1506a or an IC chip 1506b. It consists of a data output unit 1505 for recording, and a display unit 1504 for indicating whether or not its operation is formed.

Here, the fingerprint data stored in the card memory unit 1503 is obtained by scanning an ID photograph or a fingerprint through a scanning device (not shown) provided separately at a financial institution and a card issuing institution when the authentication card 1500 is initially issued. Data can be saved.

In addition, a pressure sensor 1709 or a solar cell panel 1507a is formed on the front and rear surfaces of the authentication card 1500 as a power supply 1507 for generating and storing power for the operation of the authentication card 1500, respectively. .

The card controller 1501 transmits and records a signal recorded in the tag unit 1506, that is, card information when the fingerprint data input from the scan unit 1502 and the fingerprint data stored in the card memory unit 1503 match. After using the card information by touching it twice, it is preferable to initialize the tag unit 1506 so that the card information is lost.

Alternatively, the card controller 1501 writes the card information to the tag unit 1506, and then holds the tag unit 1506 for a set time, e.g., 5 seconds for card approval. It is also desirable to initialize so that the card information is lost.

And, as an external configuration of the authentication card 1500, the basic structure in the above-described embodiment is similar, but the fingerprint recognition module (1700a) is displayed on the front of the authentication card 1500, as shown in FIG. 1700 is formed, the pressure-sensitive sensor 1709 (or solar cell, battery) is formed on the back, and the power switch unit 1703 is formed on one side thereof to operate it in use (automatically by the pressure-sensitive sensor If designed to be ON when constant current flows, this can be omitted.)

In addition, a card memory unit 1720 formed of a smart chip is formed on the upper side to store and store basic information such as an ID photo, a fingerprint, or a social security number, and when the fingerprint is scanned and matched with the stored fingerprint, the liquid crystal display 1710. It is configured to display the ID photo or the basic information.

Here, the card memory unit 1720 formed of the fingerprint recognition module 1700 or the smart chip may be flexibly manufactured to further increase the usability of the authentication card.

In particular, in the case of the fingerprint recognition module 1700, the finger portion is concave, so that the entire fingerprint is in contact, and thus the fingerprint recognition degree can be further increased.

21 is a flowchart illustrating a processing method of a fusion authentication card according to an embodiment of the present invention.

As shown in FIG. 21, first, the power source 1703 is turned on for the processing of the convergence authentication card according to an embodiment of the present invention (S1700).

When the power is turned on, it is first determined whether unique fingerprints, photographs, and basic information are registered in the card memory unit formed of the smart chip (S1700a).

If the information is not registered, scan or register a fingerprint or ID photo in the card memory unit 1720 formed of a smart chip, or register basic information such as a resident registration number (or name, corporation name, etc.) (S1710).

As such, when the desired information is registered in the card memory unit formed of the smart chip, it ends.

As a next step, if the above information is registered, the credit card is operated using the credit card.

Here, the step of registering the various information and the authentication step for determining whether to match the next step by scanning the fingerprint is indicated to continue, but it is to be divided and operated as a separate registration step and a separate information matching determination step, Registration should be done at a place equipped with a register to register fingerprints, etc. In use, power is supplied by a pressure-sensitive sensor (or solar cell, battery), and starts with the step of scanning fingerprints, which is an authentication procedure.

When the power is turned on at the time of authentication (S1700), if a unique fingerprint, a photo, or basic information is registered in the card memory unit formed of a smart chip, the process enters a step of scanning a fingerprint.

Therefore, the card holder grabs the card with his finger so as to scan the fingerprint when the card is used and touches the fingerprint with the fingerprint authentication module (S1720).

After receiving the fingerprint data input from the user's finger, the card controller 1501 compares the fingerprint data stored in the card memory unit 1503 to determine whether they match (S1730).

Here, the card controller 1501 compares the input fingerprint data with the fingerprint data of the user stored in the card memory unit 1503, and the scan information scanned by the user's finger and the information stored in the card memory unit 1503 match. In one case, the card controller 1501 outputs card information through the data output unit 1505 to record the card information in at least one of the NFC tag 1506a and the IC chip 1506b of the tag unit 1506.)

In addition, when the card information is normally recorded in the tag unit 1506, the card controller 1501 operates the liquid crystal display display unit 1508 to prove that the user or a third party can recognize that the authentication card can be normally used. Basic information such as a picture or a name is displayed on the liquid crystal display 1710 (S1740).

In the state in which the use of the authentication card 1500 is enabled in step S1740, the authentication card 1500 may be provided to another person for payment such as a cashier.

After enabling the use of the authentication card 1500 as described above, the card controller 1501 compares whether the set time has elapsed (S1750).

When the set time elapses in step S1750, for example, when 5 seconds (or 10 seconds) elapses, the card controller 1501 initializes the tag unit 1506 to the NFC tag 1506a and the IC chip 1506b. The recorded card information is lost so that the use of the authentication card 1500 is impossible.

In this case, when the card controller 1501 uses the card information by touching the authentication card 1500 once, the card controller 1501 may initialize the tag unit 1506 to cause the card information to be lost.

In this way, after the card controller 1501 initializes the tag unit 1506, the operation of the liquid crystal display display unit 1508 may be stopped to allow the user to recognize a state in which the authentication card 1500 cannot be used.

Of course, in the above-described embodiment, the step of operating the fingerprint scan unit may be performed by a card controller operating the fingerprint scan units 1520 and 1521 corresponding to the fingerprints 1 and 2 of the scan unit to print the fingerprints to the fingerprint authentication modules 1600a and 1600b. It can be adopted to recognize the fingerprint by contacting.

Although this invention has been described as being applied to a credit card, by applying its technology to a resident registration card, a photo or a name (corporate name in the case of a corporation) can be displayed by fingerprint recognition so that others cannot steal the resident registration card. It can be used in a way.

Next, a description will be given of the authentication card in the state that the authentication photo is displayed with the NFC function on the credit card.

Figure 23 is a block diagram of another authentication card of the present invention, Figure 24 is an authentication card in a state in which the photo ID is not displayed with the NFC function by the solar cell of an embodiment of the present invention, Figure 25 is one of the present invention An embodiment of the present invention is an authentication card for displaying an ID photo with an NFC function by a solar cell, and FIG. 26 is an authentication card for displaying an ID photo with an NFC function by a pressure-sensitive sensor according to an embodiment of the present invention.

As shown in FIG. 23, an authentication card (a concept including an identification card, which is the same below) 1800 is a fingerprint scan unit 1820 for generating and outputting fingerprint data by a human finger and thinning an ID picture. A scanning unit 1802 including a photo scanning unit 1821aa for attaching or scanning to a groove to generate and output an ID photo, and a basic information input unit 1822bb for generating and outputting basic information by inputting certain basic information; The card controller 1801 and the signal output from the card controller 1801 to read the fingerprint data from the scan unit 1802 and determine whether or not the fingerprint data for authenticity check stored in the card memory unit 1803, NFC A data output unit 1805 is written to a tag unit 1806 such as a tag 1806a or an IC chip (not shown), and a display unit 1804 indicating whether or not its operation is formed is formed.

In addition, the card controller 1801 is provided with a blood flow sensor 1803a for detecting the blood flow of a person at the time of fingerprint recognition and a temperature sensor 1807a for detecting the temperature of the person.

Here, the fingerprint data stored in the card memory unit 1803 is obtained by scanning an ID photograph or a fingerprint through a scanning device (not shown) provided separately at a financial institution and a card issuing institution when the authentication card 1800 is initially issued. Data can be saved.

Here it is described that the ID photo can be attached to the central portion of the authentication card (1800).

In addition, the solar cell panel 1840 or the decompression sensor 1809, and the solar panel 1840 or the decompression sensor 1809 as a power source 1807 for generating and storing power for the operation of the authentication card 1800. Emergency charging batteries 1850, which are used when operation is impossible or are formed of charging batteries that normally charge their batteries, are formed on the front and rear surfaces of the authentication card 1800 according to the design.

The emergency charging battery 1850 may be charged by the solar cell panel 1840 or the depressurization sensor 1809 by a normal operation.

The card controller 1801 transmits and records a signal recorded in the tag unit 1806, that is, card information when the fingerprint data input from the scan unit 1802 and the fingerprint data stored in the card memory unit 1803 match. After using the card information by touching once, it is preferable to initialize the tag unit 1806 so that the card information is lost.
