As shown in FIG. 7, the authentication card 1500 may include a fingerprint scan unit 1520 for generating and outputting fingerprint data by a human finger, and a designated mac scan unit 1521 for generating and outputting finger vein data. A scan unit 1502 including a bio switch unit 1522 for activating the card controller 1501 through a bioelectric generated in this case is formed, and the fingerprint or / and finger vein data is read from the scan unit 1502 and the card is read. The card controller 1501 determines whether or not the fingerprint and / or finger vein data for the authenticity check stored in the memory unit 1503 and the signal output from the card controller 1501 are transferred to the NFC tag 1506a or the IC chip. It consists of a data output unit 1505 for recording in the tag unit 1506, such as (1506b), and a display unit 1504 indicating whether or not the operation thereof is formed, this operation is a solar cell or a rechargeable battery to be described later Used .

The technical configuration of the solar cell or the rechargeable battery is designed by those skilled in the art.

Here, the fingerprint or / and the finger vein data stored in the card memory unit 1503 is the fingerprint or / and through the scanning equipment (not shown) separately provided in the financial institution and card issuer when issuing the authentication card 1500 Fingerprints and / or finger vein data acquired by scanning finger veins can be stored.

In addition, the reduced pressure power sensor 1509 is formed at the lower end of the finger receiving unit 1523 as the power supply unit 1507 for generating and storing power for the operation of the authentication card 1500.

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 in the form of another film facing the plate, and carbon powder and tungsten on the surface thereof. (TUNGSTEN) A pressure-sensitive resistance variable sensor element made of an oxide powder is stacked to form a pressure sensor that is pressed against the polymer conductor film to sense a change in resistance to pressure and transmit it as an electrical signal.

As shown in Fig. 11 (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. An electrode 2 'is formed, and a pressure sensor is formed by stacking a pressure-sensitive resistance variable pressure sensor element 3 in which carbon powder and tungsten oxide powder are mixed and laminated with a synthetic resin binder on the upper surface thereof.

In another embodiment, as shown in Fig. 11C, 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 shown in FIG. 10 is formed in a portion that is naturally pressurized when the card is held to recognize a fingerprint, and thus is easy to use and permanently generates power. Since it is treated as a phosphorus material, it is adopted as a power source for fingerprint and finger vein recognition.

The card controller 1501 records the signal recorded in the tag unit 1506, that is, the card information includes the fingerprint or / and finger vein data input from the scan unit 1502 and the fingerprint or / and finger vein stored in the card memory unit 1503. If the data match, it is preferable to initialize the tag unit 1506 so that the card information is lost after sending and recording the data and touching it once.

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.

In addition, the card controller 1501 may use various software for processing and calculating the finger vein image input from the finger vein image sensor 1521b.

For example, the Canny edge detector algorithm can be used. Gaussian filter can be applied to remove the noise of the original image as a whole. Edge the image through the Image Gradient. In other words, the sketch line of the image is extracted. Apply the Non-maximum Supression to make the edges thin (sketch line), and apply the Double Threshold to classify dark edges as solid edges and faint edges as noises as weak edges. . Finally, it deletes the weak edges, leaves only the obvious edges, and finally prints the edged image of the finger vein.

12, the solar cell panel 1507a of the IC chip 1506b and the power supply unit 1507 is provided as a tag unit 1506 on the front of the authentication card 1500 as shown in FIG. 12. In addition, a scan unit 1502 is formed, and as illustrated in FIG. 13, an NFC tag 1506a may be formed as a tag unit 1506 on the back surface.

The scan unit 1502 is provided with a finger receiving unit 1523 to place a finger to scan the fingerprint and finger vein on the front of the authentication card 1500, as shown, the finger receiving unit 1523 1502 is formed. In this case, the finger receiving unit 1523 may be formed of a transparent material through which infrared rays and visible rays of the fingerprint scan unit 1520 and the designated maxcan scan unit 1521 may be transmitted.

The fingerprint scanning unit 1520 has a visible light source 1520a and a fingerprint image sensor 1520b for capturing a fingerprint of a finger at the edge of the finger receiving unit 1523. In this case, the visible light source unit 1520a may be inclined toward the contact surface where the authentication card 1500 is in contact with the finger so that the visible line may be irradiated on the front surface of the finger, and the finger receiving unit may be in contact with the authentication card 1500. The reflective member 1520c may be formed to reflect the finger contact surface to the fingerprint image sensor 1520b at the lower portion of the contact surface of the 1523 to increase the positional freedom of the fingerprint image sensor 1520b.

Therefore, even if the fingerprint image sensor 1520b is formed at the edge, the finger contact surface may be reflected by the reflective member 1520c, so that the fingerprint of the finger may be photographed. At this time, the reflective member 1520c may be formed in a flat or curved surface according to the installation environment.

In addition, the visible light source unit 1520a and the fingerprint image sensor 1520b of the fingerprint scan unit 1520 may be formed in pairs at opposite positions, or a plurality of visible light source units 1520a may be formed.

The designated mac scan unit 1521 is a finger vein image sensor 1521b that photographs the infrared light source unit 1521a and the finger vein horizontally higher than the contact surface at which the finger and the authentication card 1500 contact at the edge of the finger receiving unit 1523. ) Is formed so that infrared light emitted from the infrared light source unit 1521a passes through the finger and is recognized by the finger vein image sensor 1521b.

Herein, the infrared light source unit 1521a and the finger vein image sensor 1521b of the finger scan unit 1521 may be formed in pairs at opposite positions, respectively, and each of a plurality of infrared light source units may be used to measure a plurality of positions of a finger. 1521a and finger vein image sensor 1521b may be formed.

The infrared light source unit 1521a irradiates infrared light having a wavelength of 630 to 1,000 nm suitable for capturing the finger vein image toward the finger receiving unit 1523, and may include one or more LEDs. Also preferably, an optical filter (not shown) may be installed to remove optical noise.

On the other hand, the infrared light source unit 1521a and the visible line light source unit 1520a are configured as a single module and installed on the outer side of the finger receiving unit 1523 so that infrared rays and visible lines are evenly distributed on the finger, thereby providing fingerprint data or / and designation. It is possible to form an optimal environment for acquiring Mcdata.

In addition, a bio switch unit 1522 is formed in the finger receiving unit 1523, and when the finger is in contact with the power controller after activating the card controller 1501 using a bioelectric generated by the difference between the temperature of the finger and the ambient temperature. The scan unit 1502 may be operated through the power of 1507.

That is, even when the power is turned off in the standby state, the card controller 1501 can be activated by the bioelectric generated when the finger contacts the finger receiving unit 1523, thereby reducing the standby power and reducing the standby power load. As a result, the size of the reduced pressure power sensor 1509 of the power supply unit 1507 can be reduced, thereby increasing space utilization.

In the fusion authentication card according to the present embodiment, when the user touches the finger receiving unit 1523 of the authentication card 1500, the bioelectric is generated by the bioswitch unit 1522 of the scanning unit 1502, and the bioelectric is generated by the bioelectric. Activate the card controller 1501. The activated card controller 1501 operates the fingerprint scan unit 1520 or / and the designated maximum scan unit 1521 of the scan unit 1502 to receive a finger through the visible light source unit 1520a or / and the infrared light source unit 1521a. Fingerprints and / or finger veins that are irradiated with visible or / and infrared rays to the fingers placed in the unit 1523 and photographed the fingerprints and / or finger veins through the fingerprint image sensor 1520b or / and the finger vein image sensor 1521b. Receive data.

Thereafter, the card controller 1501 receiving the fingerprint or / and finger vein data of the finger compares the fingerprint or / and finger vein data of the user stored in the card memory unit 1503 and matches the card information with the data output unit 1505. In the tag unit 1506, the NFC 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 all of the fingerprints and / or finger vein data and the fingerprints and / or finger vein data of the user stored in the card memory unit 1503. Not only one can be compared, but also the fingerprint and finger vein data can be fused and compared.

If necessary, the fingerprint and finger vein can be recognized simultaneously, which can significantly improve the false recognition rate of the fingerprint, thereby reducing the false recognition rate of the fingerprint, and the human body information of the finger vein can be easily recognized with just one finger. It has the effect of producing the security effect that can be done.

In this case, the finger receiving unit 1523 may be formed of a transparent material through which infrared rays and visible rays of the fingerprint scan unit 1520 and the designated maxcan scan unit 1521 may be transmitted.

Further, even when the power is turned off in the standby state, the card controller 1501 can be activated by the bioelectric generated when the finger contacts the finger receiving unit 1523, thereby reducing the standby power and reducing the standby power load. As a result, the size of the solar cell panel 1507a and the rechargeable battery (storage battery) (not shown) of the power supply unit 1507 may be reduced, thereby increasing space utilization.

Hereinafter, since it is the same technique as the above-described embodiment, the description thereof will be omitted.
