An Interoperable Payment Protocol for the Public Transit Fare Payment System

چکیده
The market for the public transit fare payment system using contactless smart cards is rapidly growing, however, the payment systems provided by different vendors are not interoperable. This paper presents an interoperable payment protocol for the public transit fare payment system using contactless smart cards. We also present implementation results of a PSAM (Purchase Secure Application Module -a secure device, typically, a chip that is embedded on the card terminal) that executes the proposed protocol to support interoperability among different contactless smart card based payment systems. Key-Words: Payment protocol, PSAM, Contactless smart card, Interoperability, Transit fare payment system
