Electronic fee collection. Information exchange between service provision and toll charging. | Status: Current

1 Scope This document specifies:

1. — the interfaces between electronic fee collection (EFC) back-office systems for vehicle-related transport services, e.g. road user charging, parking and access control;
2. — an exchange of information between the back-office system of the two roles of service provision and toll charging, e.g.:
   1. — charging-related data (toll declarations, billing details, payment claims, payment announcements),
   2. — administrative data (trust objects, EFC context data, etc.), and
   3. — confirmation data;
3. — transfer mechanisms and supporting functions;
4. — information objects, data syntax and semantics.

This document is applicable for any vehicle-related toll service and any technology used for charging. The data types and associated coding related to the data elements described in Clause 6 are specified in Annex A, using the abstract syntax notation one (ASN.1) according to ISO/IEC 8824‑1. This document specifies basic protocol mechanisms over which implementations can specify and perform complex transfers (transactions). This document does not specify, amongst others:

1. — any communication between TC or TSP with any other involved party;
2. — any communication between elements of the TC and the TSP that is not part of the back-office communication;
3. — interfaces for EFC systems for public transport;
4. — any complex transfers (transactions), i.e. sequences of inter-related ADUs that can possibly involve several APDU exchanges;
5. — processes regarding payments and exchanges of fiscal, commercial or legal accounting documents;
6. — definitions of service communication channels, protocols and service primitives to transfer the APDU.
