Introduction
It can be combined with a computer network of a bank to form a payment password system, which is composed of a shell, a keyboard, a single-chip microcomputer and a liquid crystal display module, the microcontroller selects the Random storage device Ram and mask encryption.ProgramMemory Rom microcomputer chip, so that the MCU internal mask complete encoding control procedures and EncryptionAlgorithmSo that the utility model has high accuracy, safety, good anti-deciphering, easy to use, simple structure, easy to carry and other features.
Basic Structure
A Payment Cipher, which includes a shell, a keyboard installed on the shell, a single-chip microcomputer, and a liquid crystal display module, the characteristic is that the MCU selects the microcomputer chip U which contains the random Memory RAM and the program memory Rom. The keyboard (2) is directly connected to the MCU input interface. The LCD module (3) connect to the LCD Driver (9) on the microcomputer chip U.
Main Purpose
In view of the disadvantages of traditional ticket printing methods such as poor anti-counterfeiting capability, low settlement efficiency, and difficult to control capital risks, an electronic payment password system emerged.
The principle of the electronic payment password system is that an enterprise uses the payment password issued by a bank to encrypt all elements of a bill during the issuance of a bill to generate a payment password (Payment password ), or the payment password of the corresponding ticket number printed in the form of a password envelope when the bank issues the ticket (the payment password form ), when an enterprise issues a bill, it fills in the payment password corresponding to the bill on the bill, as the main identification means for authenticity of the bill or the auxiliary identification means for printing.
Main functions
The Bank uses a computer network to quickly verify the validity and validity of the payment passwords on the bills and bills. The electronic payment and password system uses many high-tech methods such as modern computer network technology, cryptography principle, and single-chip microcomputer technology to overcome the drawbacks of traditional bill authentication methods, this greatly improves the operational processing capability and security of banks.
