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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International
Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
In other circumstances, particularly when there is an urgent market requirement for such documents, a
technical committee may decide to publish other types of document:
— an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical
experts in an ISO working group and is accepted for publication if it is approved by more than 50 %
of the members of the parent committee casting a vote;
— an ISO Technical Specification (ISO/TS) represents an agreement between the members of a
technical committee and is accepted for publication if it is approved by 2/3 of the members of the
committee casting a vote.
An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for
a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or
ISO/TS is confirmed, it is reviewed again after a further three years, at which time it must either be
transformed into an International Standard or be withdrawn.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TS 25110 was prepared by Technical Committee ISO/TC 204, Intelligent transport systems, and
CEN/TC 278, Road transport and traffic telematics.
This second edition cancels and replaces the first edition (ISO/TS 25110:2008), which has been
technically revised.

Introduction
Background and motivation
There are two payment systems dealing with electronic fee collection (EFC). The first is the central
account system using a one-piece on-board unit (OBU), and the second is the on-board account system
using a payment media such as the integrated circuit card (ICC).
ICCs have been widely used for public transport cards such as subway and bus payment means, and
electronic money cards for general purpose payments, as well as for credit cards and banking cards. ICC
is expected to be used for EFC payment means along with these global trends and provides convenience
and flexibility.
Currently, the descriptions in the existing EFC related international standards are focused on the central
account system, which is rather simple and gives more feasibility for EFC interoperability than the on-
board account system, which is complex and has more items to be settled.
With consideration of widespread use for transport cards or electronic money cards, a new international
standard relating the on-board account system using those ICCs is strongly required as shown in
Figure 1. Furthermore, a state-of-the-art mobile phone integrated with ICC functions, a so-called
“mobile electronic purse”, has been used for public transport or retail shopping as a payment means in
some countries so rapidly that standardization on this theme is important and essential for considering
future EFC payment methods as well.

Objective
The objective of this Technical Specification is to classify data transfer models based on operational
requirements, and define a specific ICC access interface for on-board account using ICC for each model.
Furthermore, this Technical Specification provides practical examples of transactions in Annex B, for
consideration and easy adoption by toll road operators.
Use
This Technical Specification provides a common technical platform for on-board accounts using ICCs to
deal with various operational requirements, and practical examples of on-board accounts actually used
or planned in several countries.
Each toll road operator can establish their own specification by selecting an example of the models in
this Technical Specification (like a tool box) so as to meet their requirements.

TECHNICAL SPECIFICATION ISO/TS 25110:2013(E)
Electronic fee collection — Interface definition for on-
board account using integrated circuit card (ICC)
1 Scope
This Technical Specification defines the data transfer models between roadside equipment (RSE) and
integrated circuit card (ICC), and the interface descriptions between RSE and on-board equipment
(OBE) for on-board account using ICC. It also provides examples of interface definitions and transactions
deployed in several countries.
This Technical Specification covers:
— data transfer models between RSE and ICC which correspond to the categorized operational
requirements, and the data transfer mechanism for each model;
— interface definition between RSE and OBE based on each data transfer model;
— interface definition for each model comprises
— functional configuration,
— RSE command definitions for ICC access, and
— data format and data element definitions of RSE commands;
— a transaction example for each model in Annex B.
Figure 3 shows the configuration of on-board account and the scope of this Technical Specification. The
descriptions in this Technical Specification focus on the interface between RSE and OBU to access ICC.

Figure 4 shows the layer structure of RSE, OBU, and ICC where the mid-layer of application interfaces are
denoted as the practical scope of this Technical Specification.
NOTE The existing standards for physical and other protocol layers both between RSE and OBE, and between
OBE and ICC, are outside the scope of this Technical Specification. For example, DSRC related items (L-1, L-2,
and L-7) and ICC related items (ICC commands, data definition, etc.) are outside the scope of this Technical
Specification.
There are two types of virtual bridges contained in an OBU. The first type is Bridge-1 on which an RSE
command sent from RSE is decomposed and ICC access command contained in application protocol data
unit (APDU) part of RSE command is transferred to ICC I/F to access ICC. The second type is Bridge-2
on which an RSE command sent from RSU is transformed to ICC access command and transferred to ICC
I/F to access ICC.
Bridge-1 corresponds to the transparent type and the buffering type defined in this Technical
Specification, whereas Bridge-2 corresponds to the cashing type.
