Description

Intelligent anti-counterfeiting financial POS machine

The present invention belongs to a financial POS machine, and particularly a collection of functions such as reading and writing smart IC cards, magnetic stripe cards, fingerprint collection, fingerprint comparison, display of image information such as photos and text information such as names, and bill printing. Integrated intelligent instrument. Background technique

In recent years, IC cards have been widely used internationally, and there is also a trend of popularization in China. For IC card products, especially "currency cards", if personal fingerprint data is stored in the card as a password, you can use the card to make purchases, deposits, transfers, and settlements in the same place or in different places. This is not only safe and reliable. And it's quick and easy. The anti-counterfeiting of the existing credit cards or "currency cards" in China depends on checking the cardholder's handwriting or identity card or personal password. However, handwriting can be imitated. Many photos of ID cards have been difficult to recognize for a long time, and it is inconvenient to use a credit card to hold another ID card. Using passwords is also a chore for users. A person may need to remember many passwords, such as his computer password, safe password, passbook password, phone password, etc. In order to be easy to remember and not easy to be stolen by others, users have to take pains Program these passwords. These passwords are also the source of leaks. For example, when handling password passbooks, many users use their birth date or other meaningful numbers as passwords for convenience of memory. This is actually very easy for others to guess. This has occurred in cases of misappropriation of credit cards or "credit cards". Disclosure of invention

The purpose of the present invention is to provide an intelligent instrument which integrates many functions such as reading and writing smart IC card, magnetic stripe card, fingerprint collection, fingerprint comparison, display of text information such as photo image information and name, and receipt printing. It can accept new-type Ic card credit card transactions, and it can also accept issued magnetic stripe credit card transactions. The invention is designed to improve the security and anti-counterfeiting performance of the current financial P 0 S machine. It includes a magnetic card reader, a fingerprint reader, an operating keyboard, and a liquid crystal display. It is characterized in that it also includes a central processing that performs functions such as fingerprint feature extraction, automatic fingerprint comparison, data decryption and decompression, logic control, and data communication. Unit, instrument master Board, micro bill printer, smart IC card reader, communication interface, the central processing unit consists of 32-bit embedded CPU chip, data storage chip set, program memory chip set, sequential logic control chip set, etc. It consists of a device, the communication interface is a dedicated expansion interface board, which includes a standard parallel communication interface connected to a receipt printer, three serial communication interfaces (one connected to the WAN through a modem, and another connected to an IC card reader. Serial communication interface of local area network), a magnetic card reader driver interface, the instrument main board is composed of AC / DC power module, keyboard decoding module, encryption module, optical fingerprint scanning interface circuit, and small screen LCD interface circuit.

Figure 12 shows the functional module diagram of the magnetic card reader T T L level to RS-232C interface. Figure 13 shows the implementation principle of the magnetic card reader interface C P L D logic device.

Referring to the figure, the main hardware modules of the instrument are: Central Processing Unit:

As shown in Figure 3, the central processing unit performs functions such as fingerprint feature extraction, automatic fingerprint comparison, data decryption and decompression, logic control, and data communication. The unit consists of a 32-bit embedded CPU chip, a data storage chipset, and a program storage Device chipset, sequential logic control chipset and other components. Dedicated expansion interface board:

The expansion interface board integrates a standard parallel communication interface (connected to a credential printer), two RS232C serial communication interfaces (one connected to the WAN through a MODEM, and the other connected to a CPU card reader), and one RS485 serial communication interface

(Composed of a local area network), a magnetic card reader drive interface (the circuit schematic diagram is shown in Figure 12), and the circuit block diagram of the expansion interface board is shown in Figure 4. Instrument motherboard:

AC / DC power module U1 provides + 5V, U2 provides + 12V, and U3 provides -12V power (see Figure 5 for its circuit schematic diagram); keyboard decoding module (see Figure 6 for its circuit schematic diagram, where U4 is keyboard decoding Chip, J1 is the standard keyboard interface socket); encryption module (the circuit schematic diagram is shown in Figure 7); optical fingerprint scanner interface circuit (the circuit schematic diagram is shown in Figure 8, where U5 is the frame grabber video input socket and U6 is optical Fingerprint scanner signal output and power socket); small-screen LCD interface circuit (see Figure 9 for the circuit schematic, where U7 is the LCD signal line, control line, power interface, U8 is the socket on the motherboard). Fingerprint acquisition module:

4X5 matrix keyboard is used, and the keyboard decoding module on the main board of the instrument scans and Decode commands and data entered by the keyboard. Structure of the instrument-The structure of the intelligent anti-counterfeiting financial POS machine is a desktop, which works with the fingerprint password keyboard to complete the normal credit card transaction process. The present invention can compare only the card holder's personal password (PIN), and can also compare the card holder's personal password (PIN) and fingerprint at the same time (this improves the security of card transactions). If the cardholder chooses the security measure that the PIN and fingerprint are compared at the same time, but on the day of the card transaction, the finger is injured and the fingerprint cannot be compared, the operator can take the photo displayed on the screen (from the card stored in the card) Person photo data) and the photo printed on the card surface and the cardholder's appearance of the three comparison. This avoids normal credit card transaction activities that cannot be performed due to a finger injury. The present invention can form a local area network (inside a super mall) through an RS485 serial communication port, or directly access a wide area network for cross-bank transactions. The invention can also run on the Internet, so the blacklist query speed is fast, and the economic loss of cardholders and card issuing banks is reduced. The present invention provides a PC / 104 embedded CPU as a hardware platform, which integrates CPU financial IC card (CPU card) reading and writing, magnetic stripe credit card reading, bill printing, fingerprint collection, and fully automatic comparison to an integrated POS machine, which can pass fingerprints. , Password, photo to identify the authenticity of the financial IC card, and can handle financial IC credit cards that store more than two fingerprints, a photo and text information at the same time in a CPU card.
