This document specifies — the interfaces between electronic fee collection (EFC) systems for vehicle related transport services, e.g. road user charging, parking and access control; it does not cover interfaces for EFC systems for public transport; an EFC system can include any EFC system, e.g. including systems that automatically read licence plate numbers of vehicles passing a toll point, — an exchange of information between the central equipment of the two roles of service provision and toll charging, e.g. — charging related data (toll declarations, billing details), — administrative data, and — confirmation data, — transfer mechanisms and supporting functions, — information objects, data syntax and semantics, — examples of data interchanges (see Annex B and Annex C), and — an example of toll rounding (see Annex D). This document is applicable for any toll service and any technology used for charging. It is defined as a toolbox standard of transactions and Application Protocol Data Units (APDUs), which can be used for the assigned purpose. The detailed definitions of mandatory and optional elements in a real implementation are defined elsewhere. It does not define all communication sequences, communication stacks and timings. The data types and associated coding related to the data elements described in clause 6 are defined in Annex A, using the abstract syntax notation one (ASN.1) according to ISO/IEC 8824-1. This document is not applicable, among others, to — any communication between toll charger (TC) or toll service provider (TSP) with any other involved party, — any communication between elements of the TC and the TSP that is not part of the back office communication, — processes regarding payments and exchanges of fiscal, commercial or legal accounting documents, and — definitions of service communication channels, protocols and service primitives to transfer the APDUs.
