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

ISO 25110:2017(E)
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.
The 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 the 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 document is to classify data transfer models based on operational requirements
and define a specific ICC access interface for on-board accounts using the ICC for each model.
Furthermore, this document provides practical examples of transactions in Annex B, for consideration
and easy adoption by toll road operators.
Use
This document 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 document (like a tool box) so as to meet their requirements.

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

Figure 4 shows the layer structure of the RSE, OBU and ICC where the mid-layer of application interfaces
are denoted as the practical scope of this document.
NOTE The existing standards for physical and other protocol layers both between the RSE and OBE, and
between OBE and ICC, are outside the scope of this document. 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 document.
There are two types of virtual bridges contained in an OBU. The first type is Bridge-1 on which an RSE
command sent from the RSE is decomposed and the ICC access command contained in the application
protocol data unit (APDU) part of the RSE command is transferred to ICC I/F to access the ICC. The
second type is Bridge-2 in which an RSE command sent from the RSU is transformed to ICC access
command and transferred to ICC I/F to access the ICC.
ISO 25110:2017(E)
Bridge-1 corresponds to the transparent type and the buffering type defined in this document, whereas
Bridge-2 corresponds to the cashing type.

5 Data transfer models
5.1 General
There are three types of data transfer models for on-board accounts using the ICC to cope with the
operational requirements described in Annex A.
5.1.1 Transparent type
The ICC command data are transferred directly from the RSE to the ICC through the OBU. The OBU
temporarily stores the ICC command data and response data in the buffer memory. See Figure 5.

5.1.2 Caching type
The EFC-related data are read out from the ICC at the presentation and stored in the SAM of the OBU. In
the DSRC communication, the EFC-related data in the SAM is transferred to the RSE. See Figure 6.

5.1.3 Buffering type
The EFC-related data which is limited to non-sensitive data are read from the ICC at the presentation
and stored in the buffer memory in the OBU. In the DSRC communication, the EFC-related data in the
buffer memory is transferred to the RSE. See Figure 7.

5.3 Transparent type
5.3.1 General
In this model, the maximum vehicle speed depends on the data transfer rate between the ICC and OBU
so that the vehicle has to stop or go through slowly under an RSE antenna in case a conventional contact
ICC is used. The feature of the transparent type is to make the OBU simple by eliminating the secure
memory inside of the OBU and the performance will be improved according to the developing ICC with
high transfer data rate.
5.3.2 Data transfer process
In this model, data exchanges between the RSE and ICC are processed directly after establishing DSRC
communication and authentication between the RSE and OBU is completed. Mutual authentication
between the ICC and RSE is processed directly before the application data are exchanged and value
data are accessed.
In the reading sequence, the READ command is sent from the RSE to the ICC through the OBU to read
out the data set stored in the ICC. In the READ response, the data set stored in the ICC is transferred
from the ICC to the RSE through the OBU. In the writing sequence, the same procedure is processed. In
case of prepaid payment, the debit command is sent from the RSE and the same procedure is processed,
as shown in Figure 9.

5.4.1 General
In this model, the OBU reads out datasets from the ICC and stores them in a secure memory inside the
OBU, upon insertion and completion of the authentication. The feature of this type is that the high data
exchange rate between the RSE and OBU is performed even when the
