Design of a New Kind of Contactless IC Card Reader Middleware

Based on the demand analysis of network operation of rail transit AFC system, a new kind of contactless IC card reader middleware is designed in order to make different non-contact IC card reader equipment compatible with each other, unify the fare calculation and achieve uniform ticket process. The contactless IC card reader middleware includes initialization module, security access module, ticket-card authentication module, fare calculation module and transaction generation module, which packages ticket business rules of rail transit and card processing procedure and interacts with application software and reader devices through a unified interfaces, so as to create a link to connect the card reader and the application software of AFC system. It is a cost-effective option to regenerate AFC systems of the old rail transit lines. It also can solve the problem of maintenance when AFC system upgrades, and reduce cost.
