This Technical Specification sets out the technical requirements to be met by contactless fare management system terminals and contactless fare media hosting a transport ticketing application in order to be able to interface together using the ISO/IEC 14443 standard contactless communications protocol.
This Technical Specification applies to:
— any contactless fare management system terminal acting as a PCD contactless reader based on ISO/IEC 14443 standard series;
— any contactless fare media acting as a PICC contactless object based on ISO/IEC 14443 standard series.
The purpose of these implementation requirements is to ensure contactless communications interoperability between contactless fare management system terminals and any contactless fare media liable to be accepted by them, once both terminal and fare media have been certified as meeting the requirements of these implementation requirements. An interface–oriented test approach will be used to evaluate the interoperability of relevant components and is defined in CEN/TS 16794-2, Public transport — Communication between contactless readers and fare media — Part 2: Test plan for ISO/IEC 14443.
Application-to-application exchanges executed once contactless communication has been established at RF level fall outside the scope of these implementation requirements. In line with the rules on independency between OSI protocol layers, these implementation requirements work on the assumption that application-to-application exchanges are not contingent on the type of contactless communication established or by the parameters used for the low-level protocol layers that serve as the platform for these application-to-application exchanges.
