Research And Development Of Multi Standard Contactless IC Card Payment Terminal Compatible Upgrade

In recent years,with the increasing demands for the interconnection of various contactless IC card standards and the vigorous implementation of the "Technical Specification for Urban Public Transport IC Cards"(JT/T978-2015)issued by the Ministry of Transportation in May 2015,the traditional contactless IC card terminals constructed with the Ministry of Housing and Construction standards will be upgraded.The integration of Multi-standard technology will surely become the mainstream upgrading scheme of application terminals in the future.Through the unified technical standards and transaction interfaces,the effective integration of various payment technical standards can improve the transaction payment environment,enhance user experience,and promote the prosperity and development of the public transport payment industry.This topic mainly around the mainstream contactless IC card payment standards,abstract design of embedded hardware driver interface,and realize the scheme of application program interfaces of Multi-standard contactless IC technology integration.In the design of this scheme,the emphasis is the research of Multi-standard IC card fusion technology,wireless radio frequency technology,embedded application development technology.This paper analyzes the technical standards of various contactless IC cards,combs the hardware architecture and software requirements of the mainstream vehicle terminal,analyzes The functional requirements,non functional requirements and application requirements;through the collation of these requirements,designs bottom driver interface and external application(API)interface of RF interactive module,storage module,etc.Through the use of abstract ticket cards,standard fusion and other technical means,the development of multi-standard IC card application interface(API)was completed.Through functional testing,project joint testing and promotion of commercial application,The research group verified the feasibility,reliability and technical safety of Multi-standard IC card fusion technology.The main work completed includes Offline consumption,balance inquiry and historical transaction inquiry of Multi-Standard contactless IC card.The main vehicle terminal can be compatible with the functional requirements of Multi-standard IC card only by software upgrade.it has also passed the acceptance test of the project,and has reached the design goal.
