Description

technical field [0001] The invention relates to the technical field of bank card payment, in particular to a system and method for realizing fast payment based on a bank smart card. Background technique [0002] In daily life, people often make some small consumption payments, such as payments in restaurants, convenience stores, movie theaters, toll parking, buses, subways, etc. This type of payment requires a fast, safe and convenient payment process. [0003] However, in the traditional bank card payment process, generally, the point-of-sale terminal sends the transaction to the bank host system in the form of a dial-up connection through the public telephone network (PSTN). This method has disadvantages such as long transaction time and high communication costs, which seriously restrict the development of electronic payment. [0004] Electronic wallet technology can solve the problems existing in traditional payment, but for accepting banks, it is necessary to deploy a p...

Problems solved by technology

This method has disadvantages such as long transaction time and high communication costs, which seriously restrict the development of electronic payment

[0004] Electronic wallet technology can solve the problems existing in traditional payment, but for accepting banks, it is necessary to deploy a point-of-sale security access module (PSAM card) at the terminal, which has great hidden dangers in terms of security and management.

In addition, from a security point of view, the electronic wallet technology uses a symmetric key system, and all keys are confidential keys, and their exchange, transmission, and update are faced with major problems; It is very inconvenient to manually recharge the account, and it is impossible to consume first and repay later like a credit card account

[0005] In recent years, with the issuance and promotion of Europay, MasterCard, Visa, EMV smart cards, the security authentication and offline payment of smart cards have been realized, but the offline authentication payment mechanism of EMV cards In this situation, due to the failure to check the offline consumption amount and account balance information, it is likely to cause the cardholder's account to exceed the limit of overdraft, thereby increasing the bank's business operation risk
