Problems solved by technology

[0020] At present, with the popularization of IC card applications in China, the application of IC cards is constantly improving, so POS applications need to be upgraded for IC card applications, especially the EMV2000 migration plan in the financial industry. EMV is an international credit card organization. , EMV2000 is the latest version of the EMV organization's credit card application specification. It puts forward newer and more powerful functional requirements for the original POS machine, such as adding the RSA asymmetric encryption algorithm and replacing the IC card operation process of the transaction. The RSA algorithm is currently The most widely used asymmetric encryption algorithm, the DES algorithm is the most widely used symmetric encryption algorithm, and the EMV2000 specification specifies these two algorithms as the encryption algorithm approved by EMV; under the original POS frame structure, this upgrade must To replace a new central processor, only the host of the POS machine can be replaced, and the cost is very huge

Abstract

In the invention, based on original POS machine structure, replanting corresponding function (such as card reader, algorithm processing, and control module) into the encipher keyboard, adding communication protocol between keyboard and POS machine conveniently to update hardware. It is also simple to update software.

Description

technical field [0001] The invention relates to the technical field of computer communication and data confirmation, in particular to a POS machine commonly used in commercial transactions. Background technique [0002] POS (Electronic Cash Register System) Abbreviation for point of sale, generally referring to the place in the mall where payment is made for the purchased goods. In general, POS refers to a computerized transaction system used in automated supermarkets, utilizing scanners to read labels and barcodes, electronic cash registers, and other specialized equipment to record revenue at the point of sale. POS machine refers to the terminal used for this process. [0003] At present, POS machines are widely used in the market, whether it is in finance, refueling, telecommunications and other industries, especially when the number of users of IC cards increases, it greatly facilitates the use of cardholders. [0004] At present, the POS machines used in China are div...
