Design And Implementation Of Consumer System Based On Smart Card

Various enterprises and universities have successively created and improved intranets,providing a good network platform and technical support for the establishment of enterprises and college card systems.The development of a card management platform within the enterprise and the university has become an absolute trend in which the management level is gradually improved and the management technology measures are digitized.This thesis studies,designs and implements a high-quality system platform with good application prospects.The system application scope is for enterprises or colleges,and the card can be mainly used for elevator control,card punching and card consumption.The consumer system modules studied in this paper are used in corporate cafeterias,supermarkets,and any place where credit card consumption can be made.This thesis draws a comprehensive functional requirement through research,compares two common system and equipment joint adjustment schemes,analyzes its advantages and disadvantages,selects the most suitable scheme,and studies system security and stability in the design phase.The business and process of the system are expounded,and the problem of simplifying the transaction process under the premise of ensuring transaction security is analyzed.Docking the three types of devices,such as the card writer,consumer machine and subsidy machine,the card is encrypted by the key configuration algorithm.The card key is the unique identifier of the system and device to identify the system card.This is the innovative part of this thesis.Through this system,the administrator can operate the card writer to perform card management and recharge management on the IC card.Among them,the specific functions of card management include applying for a system card,reading card data,replenishing cards,reporting loss,and unmounting.The enterprise management personnel operate the consumer machine for subsidy payment,and the merchant can operate the consumer machine to swipe the card and set the consumption mode.The data in the consumer machine in the online state is automatically uploaded to thesystem to form a statistical report.In combination with the current development trend,the most popular front-end and rear-end separation framework is used to build the software system part,and the flat design realizes the consumption automation and integration of the card.
