| With the popularity of smart phones and mobile Internet gradually,emerging mobile payment,mobile payment has already begun into all aspects of life people,mobile payment development speed quickly,can see the figure of it almost in every scene,urban public transport as a medium,the mobile payment card must be and fusion of Internet technology,not only meet the daily traditional habits of credit card.Mobile payment drives the increasing maturity of QR code technology,which promotes the combination of onecard and two-dimension code.The application of public transport one-card has played a huge role in the travel of residents,and it has brought a convenient way of life for citizens and has become an indispensable part of people’s life.And to attract a large number of users with various preferential policies.At present,there is a great potential for the development of the cartoon.The strong demand of the market has continuously upgraded the industry on the technical level and promoted the further improvement of the industry.Under the widespread popularity of Internet giant enterprises,QR code payment is accepted by consumers with its convenient and convenient payment experience.QR code as a mature image data coding technology,with a mobile phone hardware requirements low,faster recognition,can support users has advantages,obtain more and more widely application,especially in July 2017,the ministry of transportation information center issued a "traffic all-in-one-card QR code pays technical requirements".It caused a great sensation and aroused the enthusiasm of the industry.In addition,the public also made strong demands on the application of QR code payment technology in the transportation industry.I took part in this paper software code design,the function of the whole system debugging and the writing of the software works and related patent,this paper is done to the development of a comprehensive summary and review.Pay based on urban traffic,and the trend of the development of the market,this paper proposes a payment system based on urban public transport QR code,on smart phones,app QR code generated by mobile phones transportations to the virtual card installed on a mobile phone,using a mobile phone to charge.Quick passage.Around this system,the main research work of this paper includes the following.According to the technical requirements,to in-depth study of the principle of the QR code,including QR code to pay the safety and efficacy of traffic,trade data integrity and non-repudiation,and a variety of design principles,offline transaction implementation,the implementation of the key security mechanism,the choice of encryption algorithm,blacklist management system implementation,as well as the terminal complete calibration system and background accounts processing system research and design. |
