Design And Implementation Of Urban Traffic Card Online Consumption System

With the development of the mobile Internet, the transportation card face the challenge of a variety of new technologies, as a form of payment profession, traffic card has not only limited in the development in the field of professional industry and its business forms can be extended to the direction of the mobile Internet. On the other hand, the smart phone with NFC function has been widely existed in our society. In this scenario, the urban public transport card and smart phones are combined to build an online consumer system for intelligent transportation. For the development of urban public transportation card in the field of mobile payments is significant. In this context, the proposed use of smart phones with NFC function analog "class POS Terminal" card read and write operations on the traffic program, With NFC Near Field Communication technology to make mobile Internet traffic card can be "beat card" consumer, The main research work includes the following aspects:(1) Research on the strategy of security authentication. The traditional scheme is:in the consumer terminal and PSAM card for communication directly to complete the key authentication.If this program directly migrate to the scene of the smart phone consumption, there will be difficulties in the implementation of technology, cost, and so on.Aiming at the above problems, this paper proposes a new strategy with PSAM random array under the key to complete the certification, PSAM array of new strategy deployment at the back end of the on-line consumer. Compared with the traditional front-end security authentication method, not only has the ability of security and authentication of the payment transactions, also have good practical ability to deploy and extensible function.Guidance and implementation system construction and operation of a reference significance.(2) High availability and scalable performance improvement for the online consumer platform.Firstly, we combine technology Alibaba open source framework for distributed Dubbo, Dubbo framework is designed to achieve the high availability features of remote service invocation.Based on the application of such a distributed open source framework, so as to meet the needs of efficient processing of online consumer services.In addition, this paper proposes the methods of improving and optimizing the two parts to build high availability and scalable system, which can solve the problem that the background system can not keep up with the expansion of the business.(3) For city bus card mobile payment scenarios, combined with the above policy and safety certification program to enhance system performance, the paper online consumer system design and implementation, and test analysis to verify the reliability of the online consumer system.
