Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 204, Intelligent transport systems.
This second edition cancels and replaces the first edition of ISO/TS 21192:2019, which has been technically
revised.
The main changes are as follows:
— Clause 3 has been updated and ISO/TS 17573-2 has been made the primary source for terms and
definitions;
— data definitions have been updated, including referring to ISO 17573-3 as the primary source;
— ISO 21177 is now referenced for inclusion of secure data transfer mechanism in subclause 7.1;
— the data elements that originated from EN 1545-2:2015 are formally defined in the ASN.1 module.

Introduction
Transportation network improvement, including road and railway, is essential to drive economic growth.
Integrated transport service has been aimed at topics such as user convenience, transport safety, reliability,
efficiency and availability. For example, a traffic manager can find which kinds of improvements are needed
to relieve traffic bottlenecks by analysing user transport flows in a transport system considered as a whole.
It is usually necessary to use different transport services to transfer people or goods from origin to
destination. Sometimes, using different transport services in the same trip becomes cumbersome when
transport services are operated by different operators, e.g. bad interconnections between different
transport modes due to user needs to search and compare transportation modes, need for separate
charging or payment for the transport services used. The connections between different transport modes
and the means to achieve seamless travel are improving with the use of information and communication
technologies (ICT).
ISO/TR 19639 investigated case studies on the use of a common payment medium when combining public
transport services and road services, based on the use of a common payment schema. This common payment
schema is further categorised into integrated central accounts and integrated on-board accounts.
ISO/TR 19639 concluded by stating the need for new electronic fee collection (EFC) standards to support on-
board integrated accounts, among which is an application interface between the common payment medium
and the common service rights provider (CSRP). The background of on-board accounts in EFC are as follows.
— Operational methods of EFC systems might be different due to regional and local circumstances. EFC
systems can be classified into central accounts and on-board accounts, using a common payment
medium, which are widely adopted in Asian countries.
— On-board account payment media are commonly used for public transport in several countries, e.g.
Singapore, Malaysia and China.
— Central payment accounts are considered one of the common service rights methods explained in
ISO/TR 20526, whereas the EFC standards are currently predominantly based on central accounts.
— A convergence on the usage of on-board account for both EFC systems and public transport should be
considered.
This document describes an EFC application as one type of transport service specific application and the
application interface requirements for a common service rights application. A common service rights
application is explained in informative Annex C of this document for understanding a common payment
scheme based on this concept as shown in Figure 1.

document.
NOTE 2 Arrowed line (2) labelled 'Transport service' is not an ICT interface but a physical transport service.

Figure 1 — Common payment medium concept for EFC scheme
This document extends the set of EFC standards to allow provisions for multi-modal transport services by
using a common payment medium.
This document defines, among others, the role and responsibilities of a CSRP. The CSRP provides a common
payment medium for enabling use of EFC, a public transport service and retail shopping service to service
users with one account. CSRP may provide the usage record of user's multi-modal transport trip as a form of
customer service.
This document contains several annexes.
— Data type specifications are given in the Annex A, an implementation conformance statement (ICS)
proforma is given in Annex B.
— The common payment medium concept for any transport service is presented in the Annex C.
— General types of application structures in a medium are presented in the Annex D.
— General requirements from medium relating standards are presented in Annex E.
— A typical system migration method and technical solution supporting medium upgrading are presented
in Annex F. Examples of reloading types and transactions are presented in Annex G.
— The EFC security requirements for a common payment medium are presented in Annex H based on EFC
functional requirements.
The scope of this document includes an EFC application interface for a common payment medium as shown
in Figure 2, as well as the role and responsibilities of a CSRP.
Figure 2 explains the relation of CSRP among related sectors including EFC. E-money is exchanged between
the Transport Service Provider (TSP) in the EFC sector and the CSRP. E-money is exchanged between retail
in the commerce sector and the CSRP.
