Intelligent financial card-reading system

Abstract

The invention provides an intelligent financial card-reading system. A point-of-sale (POS) terminal acquires transaction information which comprises transaction type, transaction amount and transaction serial number, and combines the transaction information into a corresponding bank card transaction request message; the message does not comprise card information, the personal identification number (PIN) of a bank card, Europay, MasterCard and VISA (EMV) migration relevant data and message authentication code (MAC) signature information; the information can be acquired by swiping the bank card and inputting the PIN on the basis of cooperation of all modules of the intelligent financial card-reading system, and filling a complete transaction request message; a card reader returns processed transaction request data to the POS terminal; the POS terminal continuously communicates with a bank system and is required to forward a response message which is returned by the bank system to the card reader; and the card reader judges whether transaction succeeds. By adoption of the intelligent financial card-reading system, the POS terminal can be simplified to a great extent, the development difficulty of the POS terminal is reduced, and reforming of EMV migration is realized with low cost.

Description

【Technical field】 [0001] The invention relates to the technical field of communication equipment, in particular to an intelligent financial card reading system. 【Background technique】 [0002] EMV is a chip card specification jointly formulated by the three major international bank card organizations Europay, MasterCard, and VISA. It is an interactive dialogue mechanism between chip cards and chip terminals. [0003] EMV migration is the transfer of bank cards from magnetic stripe cards to integrated circuit (IC) cards, using smart IC cards with higher security instead of magnetic cards to effectively prevent various types of fraud such as making and using fake credit cards, credit card fraud, and transnational financial fraud. High-tech means of financial crime. EMV migration is the process of converting bank cards from magnetic stripe cards to smart IC cards. It is a financial payment standard based on the CPU IC card and has become a recognized framework standard. Its ...

AI Technical Summary

Problems solved by technology

[0005] The existing technology of EMV migration and transformation of POS system terminals has the following defects: 1. For POS terminal manufacturers without financial IC card core technology, the workload of EMV business processes is very huge, and strict testing and certification by EMV organization is required

[0006] 2. For bank messages after EMV migration and transformation, POS terminals need to receive and return the data required for abstract financial IC card transactions, which is difficult for POS business developers who have never been in touch with financial IC cards to understand

[0007] 3. The EMV business process generally requires dozens of IC card command interactions. If the card reader only provides the command data communication interface of the IC card, then there are many direct interactions between the POS terminal and the card reader for a transaction, which will affect the system. transaction time and stability

[0008] 4. The offline plaintext PIN (personal bank card password) verification method needs to be supported in the EMV business process, so when the POS terminal sends a plaintext PIN verification command (Verify command), it will transmit the plaintext PIN to the card reader, which is easy to form a PIN Security risks
