This document specifies: — the interfaces between electronic fee collection (EFC) back-office systems for vehicle-related transport services, e.g. road user charging, parking and access control; — an exchange of information between the back-office system of the two roles of service provision and toll charging, e.g.: — charging-related data (toll declarations, billing details, payment claims, payment announcements), — administrative data (trust objects, EFC context data, etc.), and — confirmation data; — transfer mechanisms and supporting functions; — 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: — any communication between TC or 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; — interfaces for EFC systems for public transport; — any complex transfers (transactions), i.e. sequences of inter-related ADUs that can possibly involve several APDU exchanges; — processes regarding payments and exchanges of fiscal, commercial or legal accounting documents; — definitions of service communication channels, protocols and service primitives to transfer the APDU.
Abstract
Overview
SIST EN ISO 12855:2025 / ISO 12855:2025 defines the information exchange between electronic fee collection (EFC) back-office systems that support vehicle-related transport services such as road user charging, parking and access control. The standard specifies interfaces, data objects, transfer mechanisms and the data syntax and semantics needed for reliable back-office communication between the two principal roles - service provision (TSP) and toll charging (TC). It is applicable to any vehicle-related toll service and any charging technology.
Key technical topics and requirements
- Interfaces and roles: Defines how EFC back-office systems interact between toll chargers and toll service providers.
- Information objects and ADUs: Specifies Application Data Units (RequestAdu, AckAdu, StatusAdu, TrustObjectAdu, EfcContextDataAdu, etc.) and their structure for exchanging messages.
- Data syntax & semantics: Data types and coding for Clause 6 are provided in Annex A using ASN.1 (abstract syntax notation one) in accordance with ISO/IEC 8824-1.
- Transfer mechanisms & protocol primitives: Basic protocol mechanisms are defined to support implementations that may build complex transactions on top.
- Key data categories:
- Charging-related data: toll declarations, billing details, payment claims, payment announcements.
- Administrative data: trust objects (certificates, keys), EFC context data, versioning and validity.
- Confirmation & status data: acknowledgements, enforcement status, exception lists, CCC events.
- Supporting functions: Quality assurance parameters, user details and lists, media settlement data, reporting abnormal behaviour and handling exception lists.
- Security & trust: Exchange and format for trust objects and authentication of data elements are included.
- Scope exclusions: Does not cover communications with other parties, internal TC/TSP communications not part of back-office, EFC for public transport, payment processes, fiscal/accounting document exchanges, or service channel/protocol primitive definitions.
Practical applications and who uses it
This standard is intended for:
- Toll operators and toll chargers (TC) implementing interoperable back-office systems.
- Toll service providers (TSP) and mobility service providers managing billing and settlements.
- Systems integrators and ITS vendors developing EFC back-office software, APIs and data schemas.
- Public authorities and regulators specifying procurement or interoperability requirements for road charging and parking schemes. Use cases include cross-border tolling, multi-operator settlement, secure exchange of billing and payment claims, and standardized trust object exchange.
