scope:

This document constitutes the 3rd edition of CEN/TS 16794-1. It sets out the technical requirements to be met by contactless Public Transport (PT) devices in order to be able to interface together using the ISO/IEC 14443 series contactless communications protocol. This document applies to PT devices: - PT readers which are contactless fare management system terminals acting as a PCD contactless reader based on the ISO/IEC 14443 series; - PT objects which are contactless fare media acting as a PICC contactless object based on the ISO/IEC 14443 series. This edition addresses interoperability of consumer-market NFC mobile devices, compliant to NFC Forum specifications, with above mentioned PT devices, aligns with the 4th edition of the ISO/IEC 14443 series and maintains the possibility for PT readers to comply with the requirements from EMV Contactless Interface Specification [1] and the present document. An interface-oriented test approach is used to evaluate the conformity of PT devices and is defined in CEN/TS 16794-2. Application-to-application exchanges executed once contactless communication has been established at RF level fall outside the scope of this document. In line with the rules on independence between OSI protocol layers, this document works on the assumption that application-to-application exchanges are not contingent on the type of contactless communication established or the parameters used for the low-level protocol layers that serve as the platform for these application-to-application exchanges.
