Description
Technical field
The present invention relates to a kind of method of payment and system, a kind of method of payment and system based on bar code are related in particular to.
Background technology
With the popularization of mobile Internet, more and more traditional industries are driven to interconnect the development of networking, particularly traditional retail shop or restaurant unit.The development of Quick Response Code application and the development of Third-party payment, such as wechat are paid, and Alipay is paid, everywhere all among our life.Increasing convenience store, restaurant, supermarket, market all use the means of payment based on bar code.Such as purchase by group, purchase by group in early days and consumption checking is carried out using short message, mobile phone receives the password with string number, verified according to numeral at businessman.Nowadays the consumption validating documents purchased by group have developed into using two-dimensional code scanning checking, and Quick Response Code is big because of its information memory capacity, and can prevent from causing damage because of information leakage using encryption technology.The APP (application program of mobile phone) that existing Third-party payment platform such as wechat, Alipay are required in merchant terminal, consumer's mobile terminal is connectable to the background server of Third-party payment platform, could complete the flow paid.Traditional retail shop or restaurant unit, its existing scanning barcode cash register do not possess the also certain proportion of network savvy.But as the fast development for the business that purchases by group, more and more consumers possess consumption certificate, add-on third party payment platform is faced with scrap build or replacement.Therefore, it is desirable to have a kind of method of payment and system of supporting offline electronic payment to verify, the device end that meeting to network carry out the checking to client's evidence for payment.
Chinese patent literature CN102903045A《A kind of offline electronic payment method of interconnected network mode》, disclose a kind of offline electronic payment method based on bar code.Step 1：Enter system after the registration of logging in system by user door, parameters are set.Step 2：User carries out the payment of Third party system.Step 3：Backstage payment system obtains user's pay status, and user, which pays, successfully then generates virtual electronic evidence for payment, such as Quick Response Code.Step 4：User selects the voucher (Quick Response Code) and downloads or print.Step 5：User is paid the voucher (Quick Response Code).Step 6：The system barcode scanning voucher, reads data therein.Step 7：System validating documents data, think this evidence for payment effectively if good authentication, and the state of the juxtaposition voucher is to have used.Because Quick Response Code is generated by backstage payment system, is issued to user terminal after generation again.More downloading data flow can be so produced, when backstage payment system needs to generate a large amount of Quick Response Codes, data volume is more huge, easily cause download transmission delay and mistake.Meanwhile, user needs to enter system setting parameters before paying, and payment step is relatively complicated.
The content of the invention
For this, the technical problems to be solved by the invention are that the offline electronic payment method Quick Response Code of interconnected network mode in the prior art needs to be generated by backstage payment system, need to expend in downloading process compared with various flow, when backstage payment system needs to generate a large amount of Quick Response Codes, data are larger, easily cause download transmission delay and mistake.User needs to initially enter system in payment process sets parameters manually, and payment step is relatively complicated.
In order to solve the above technical problems, the technical scheme used of the present invention：
