Detailed description of the illustration

The smart card of the present invention is a smart card device, including a connector (1'), which is connected to the CPU by a data bus, VCC and CLK built in a plastic card module. The CPU is connected to the scan detector of the fingerprint reader by a bus bar inside the device through a biometric sensor equipped with a related memory processor. The bus bars inside the device are connected to RAM, ROM and EPROM integrated memory.

The following is a detailed list: 1) The contact is connected to the CPU

The contacts are manufactured in accordance with ISO standards: including an input supply timing device and a half-duplex sequence link.

2) Biometric sensor:

This biometric is a fingerprint recognition scanning detection sensor, which can provide a safe intelligent identification function, and avoids the problem that the fingerprint needs to be correctly placed.

The processor and the memory device are integrally molded from plastic without the need to wrap the outer casing.

3) Busbar inside the device

The busbar inside the unit is mainly used to connect the CPU and the biometric device (2').

a) Start the personal smart card only once at the beginning:

i. The correct identification biometric data can be established by an authorized user, and the biometric data is stored only in the memory of the smart card and cannot be read by the outside, so that the external smart card device cannot be read. Or detect this information.

Ii. also establish and store the user's personal data and access codes;

b) When using again:

i. The biometric data used only for internal identification of the device can be compared with the data that the user actually performs biometric reading again to know whether the current biometric data matches the stored data, but only the smart card. Internal inspection, cannot be read by external devices, then

Ii. After verifying the identification of personal data and access codes, normal work can be allowed.

This method can absolutely prevent the forgery of the smart card or any forgery of using the card, because unauthorized users will: a) Not only can not have individual access data and passwords, but also b) unable to establish or reconstruct new biometric identification data, and can no longer update the biometric identification data.

In addition, the privacy of personal biometric data produced by this method is not stored in an external server device, and the risk of unauthorized use of the data for unauthorized use can be avoided.

The advantage is to make a smarter smart card to avoid damage to the processor (CPU) and biometric data memory, while the memory and silicon wafer and / or microprocessor, electronic connector, is coated with epoxy Resin.

shell:

The voltage supply range is approximately 4.75-5.25V.

The maximum current is preferably in the range of about 200 mA.

This smart card includes a data tape and an RFID sensor.

Using this method, you can make a very lightweight (0.54mm) smart card that can be used in your pocket, just like all traditional magnetic card designs.

5 biometric data

In a preferred solution, a fingerprint reader (2) is used in which the scanning mobile finger is moved laterally on a square window on the same side as the scanner, the scanner being wrapped in the same card as the contact (1) and Located on the opposite side of the contact (1).

Using this method, a more significant function can be obtained. After the insertion, the power of the smart card can be activated by the contact providing power.

Only at this time, the fingerprint of the user is scanned by the external fingerprint window.

The scanning function can be started by directly inserting the fingerprint identification card vertically. This method of operation only starts when the card is inserted by an authorized user.

As shown in Figure 3, the personal smart card contains the memory data +RAM+ROM and EPPROM that are generally used.

As shown in FIG. 3, the digital fingerprint reader (2) includes a digital fingerprint recognition enhancement device (21) that couples the sensor device (22) and the memory processor (23).

A preferred method includes two microprocessors, a first microprocessor located on the underside of the electrical contacts (1) for card management functions, and a second microprocessor for biometric data analysis. In the side position, both microprocessors are connected to a busbar (3) made of flexible material.

The method has the advantages of being safe and powerful, and is also designed to be thin and light, and two microprocessors are mounted on opposite sides to provide flexibility in use.

Other preferred functions provide DNA analysis functionality for the biometric receiver (2) device. According to this method, DNA data can be compared, a smarter smart card can be made, and other parameters can be integrated, and in fact, it can no longer be forged.
