5 Conformance
To claim conformance to this document, the following requirements shall be met:

— for a PT reader, all the requirements listed in Clause 8 that are applicable according to the applicant's

ICS, under the test conditions stipulated in Clause 11 and following the PCD test plan defined in

ISO/IEC TS 24192-2;

— for a PT object, all the requirements listed in Clause 9 that are applicable according to the applicant's

ICS, under the test conditions stipulated in Clause 11 and following the PICC test plan defined in

ISO/IEC TS 24192-2.

Conformance of NFC mobile devices is tested according to NFC Forum specifications and is out of scope

of this document.

The description of the certification or qualification processes to be carried out for demonstrating the

conformance of PT devices to this document is out of scope of this document.
6 Dual conformance of PT devices to ISO/IEC TS 24192 (all parts) and EMV
Contactless Interface Specification
[1]

It is acknowledged that next to this document there is also EMV Contactless Interface Specification

relevant for many PT devices; therefore this document is developed such that PT devices can comply

[1]

with the requirements of both EMV Contactless Interface Specification and this document.

7 Interoperability of PT devices and NFC mobile devices
7.1 Description of the “concept for interoperability”

The contactless interface for NFC mobile devices follows the implementation and test specifications of

[3] [4]

the NFC Forum as specified by the NFC Forum and referenced in GSMA TS.26 and TS.27 .

The ISO/IEC 14443 (all parts) contactless interface of PT devices is designed and tested according to

the rules defined in this document.

The concept for interoperability is established to synchronise the specifications for the contactless

interface of NFC mobile devices and those for the contactless interface of PT devices in order to:

— facilitate interoperability between NFC mobile devices and PT devices;
— avoid unnecessary test and certification effort.
[5] [6]

The NFC Forum conducted a comparison of NFC Analog Specification and NFC Digital Specification

with ISO/IEC 14443 (all parts) and ISO/IEC 10373-6. Procedures that support correlation between

results from tests according to NFC Forum specifications and those according to ISO/IEC 10373-6 have

been defined.

The correlation is used to translate test results from the NFC Forum’s terminology into ISO/IEC 10373-6’s

method for describing the relevant parameters. This is the foundation for the following characteristics

of the concept for interoperability:
a) Development of PT devices and NFC mobile devices

Despite the fact that different methods for describing the relevant parameters are used, this

document and the relevant implementation specifications from the NFC Forum can be synchronised.

By synchronising the implementations’ specifications, interoperability is integrated into the design

processes of NFC mobile devices and PT devices and makes it a common feature for both types of

devices.

ISO/IEC TS 24192-1:2021(E)
b) Test and certification of PT devices and NFC mobile devices

Based on the concept for interoperability it is possible to judge if an NFC mobile device that went

through NFC Forum testing is interoperable with a PT device that complies with the requirements

for ISO/IEC 14443 (all parts) set out in this document. Therefore, it is sufficient evidence of

interoperability to test and certify ISO/IEC 14443 (all parts) conformant PT devices according to

ISO/IEC TS 24192-2 and to test and certify NFC mobile devices according to NFC Forum’s test and

certification procedures.

The detailed methodology used to demonstrate the concept of interoperability between NFC Forum

compliant devices and ISO/IEC 14443 (all parts) compliant devices is described in Reference [8].

Table 1 summarizes how contactless communication can be ensured either via conformity testing

between PT readers and PT objects or via interoperability testing between PT devices and NFC mobile

devices.

7.2 References for implementation and test of NFC mobile devices

The applicable NFC Forum specifications for designing and testing the contactless communication of

NFC mobile devices are listed in the Bibliography (References [2] to [7]).

Conformance of NFC mobile devices to these specifications is a prerequisite to ensure interoperability

of NFC mobile devices with PT devices as presented in Table 1.
7.3 Limitations

Only parameters, parameter settings or modes of operations that are relevant for PT use cases have

been regarded and aligned with for both NFC mobile and PT devices. These use cases are described in

[2]

the STA document "Documentation of Use Cases for NFC Mobile Devices in Public Transport" .

The following parameters, settings or modes are currently not covered by the harmonization of

specifications according to the concept for interoperability described in 7.1:
a) communication bit rates higher than f /128 (~106 kbit/s);
b) peer-to-peer mode according to NFC Forum specifications;
c) ISO/IEC 18092 mode of communication;
d) ISO/IEC 15693-2 mode of communication.

8 Requirements and recommendations applicable to PT readers
8.1 General
8.1.1 Overview
8.2 and 8.3 define requirements; and 8.4 defines recommendations for PT readers.

The requirements and recommendations on PT readers are identified by a numbering format that reads

[Rdrnn] where nn is the number of the requirement or recommendation.
There are two categories of PT readers:
— IFM reader;
— common reader.

All implementation requirements and tests that are necessary to achieve interoperability between PT

readers and PT objects are mandatory for both PT reader categories.
8.1.2 IFM reader

The first category, the “IFM reader”, covers use cases where performances (i.e. operating distance,

transaction time, etc.) are key. As shown in Figure 1 and Figure 2, the IFM reader shall offer an operating

range that covers the full scope of range A and range B defined in 11.3.3.2 and 11.3.3.4 respectively. All

the test positions are defined in Table 3 and Table 4.

Position A1 of range A and Position B1 of range B may be at a different position on the IFM reader, see

11.3.3.

---------------------- Page: 11 ----------------------
ISO/IEC TS 24192-1:2021(E)
Figure 2 — Range B test positions for IFM reader
8.1.3 Common reader

The second category, the “common reader", is defined for scenarios that impose requirements on the

contactless interface such as minimization of cost or maximization of battery life of the PT reader.

These requirements have been derived from use cases from the following parts of the PT operator’s

system implementation which are described in the STA document “Documentation of Use Cases for NFC

[2]
Mobile Devices in Public Transport” :
a) sales infrastructure;
b) customer’s home infrastructure;
c) mobile inspection terminals.
Some requirements given in this document are adapted for common readers.

As shown in Figure 3, the common reader shall offer an operating range that covers a limited subset of

range A defined in 11.3.3.2. All the test positions are defined in Table 3.

---------------------- Page: 12 ----------------------
ISO/IEC TS 24192-1:2021(E)
Figure 3 — Range A test positions for common reader
8.2 General requirements

[Rdr1] The PT reader shall meet the requirements for PCD defined in the ISO/IEC 14443 (all parts) and

pass associated ISO/IEC 10373-6 test methods.

NOTE 1 The PT reader is tested against Reference PICC 1, Reference PICC 2 and Reference PICC 3 only,

corresponding to the mandatory PICC classes “Class 1”, “Class 2” and “Class 3”. No test is required with Reference

PICC 4, Reference PICC 5 and Reference PICC 6 corresponding to the optional PICC classes “Class 4”, “Class 5” and

“Class 6”.

NOTE 2 There are no particular restrictions to PT readers for accepting contactless objects using any value

for Application data field (Type B).
[1]

NOTE 3 EMV Contactless Interface Specification imposes that the extended ATQB option not be supported.

ISO/IEC 14443-3 considers that the support of this feature is optional.
[Rdr2] For IFM readers:

— In all range A test positions (see Figure 1), the IFM reader shall comply with all the [Rdr1]

requirements when tested with Reference PICC 1, Reference PICC 2 and Reference PICC 3.

— In all range B test positions (see Figure 2) when tested with Reference PICC 3, the IFM reader shall:

— comply with all the [Rdr1] requirements;
— provide a field strength of at least 2 A/m (rms).
[Rdr3] For common readers:

— In Position A1, Position A1,1, Position A1,2, Position A1,3, Position A1,4 and Position A2 (see

Figure 3), the common reader shall comply with all the [Rdr1] requirements when with Reference

PICC 1, Reference PICC 2 and Reference PICC 3.
— There are no requirements applicable to range B.

---------------------- Page: 13 ----------------------
ISO/IEC TS 24192-1:2021(E)

NOTE 4 These minimum operating distance ranges are added as complementary requirements to

ISO/IEC 14443-2. Operating distance ranges A and B are defined in 11.3.

NOTE 5 The minimum field strength requirement in range B is set to anticipate future acceptance of objects of

optional classes “Class 4”, “Class 5” and “Class 6”.

[Rdr4] The PT reader shall use an AFI of '00' in at least one REQB/WUPB command in its polling

sequence.
8.3 Requirements on polling and recognizing contactless objects

This subclause defines the requirements on the polling sequence of contactless objects.

[1]

NOTE 1 EMV Contactless Interface Specification defines specific polling requirements which can impact the

transaction time.

[Rdr5] The time-to-detection of a Reference PICC requiring minimum SFGT (no SFGI or SFGI = 0) by the

PT reader shall be less than t = 250 ms. This remains a valid requirement regardless of the moment

detect

when the Reference PICC is placed within range A or B of the PT reader. The Reference PICC time-to-

detection is defined between the moment when the Reference PICC is placed into the field and the send-

out of the first I-block sent by the PT reader. The Reference PICC time-to-detection shall be the average

value measured on 10 consecutive measurements and shall be provided by the testing laboratory as

part of the result report.

NOTE 2 Some PT networks can require a maximum applicative transaction time that imposes a time-to-

detection much shorter than t .

Introduction

This document defines the requirements related to the use of ISO/IEC 14443 (all parts) to ensure

interoperability between fare management system terminals and multiple-form-factor contactless fare

media (smartcards, e-tickets, mobile phones, USB keys, tablets, etc.).

These implementation requirements are not designed to repeat or duplicate the referenced

specifications, essentially ISO/IEC 14443 (all parts) and ISO/IEC 10373-6, but to complement those

specifications with public transport specific considerations.

TECHNICAL SPECIFICATION ISO/IEC TS 24192-1:2021(E)
Cards and security devices for personal identification —
Communication between contactless readers and fare
media used in public transport —
Part 1:
Implementation requirements for ISO/IEC 14443 (all parts)
1 Scope

This document defines the technical requirements to be met by contactless public transport (PT)

devices in order to be able to interface together using the ISO/IEC 14443 (all parts) contactless

communications protocol.
This document applies to PT devices:

— PT readers which are contactless fare management system terminals acting as a PCD contactless

reader based on ISO/IEC 14443 (all parts);

— PT objects which are contactless fare media acting as a PICC contactless object based on

ISO/IEC 14443 (all parts).

This document addresses interoperability of consumer-market NFC mobile devices, compliant to NFC

Forum specifications, with above mentioned PT devices, aligns with ISO/IEC 14443 (all parts) and does

not seek to limit compliance for PT readers with EMV Contactless Interface Specification.

5 Conformance
To claim conformance to this document, the following requirements shall be met:

— for a PT reader, all the requirements listed in Clause 8 that are applicable according to the applicant's

ICS, under the test conditions stipulated in Clause 11 and following the PCD test plan defined in

ISO/IEC TS 24192-2;

Conformance of NFC mobile devices is tested according to NFC Forum specifications and is out of scope

of this document.

The description of the certification or qualification processes to be carried out for demonstrating the

conformance of PT devices to this document is out of scope of this document.
6 Dual conformance of PT devices to ISO/IEC TS 24192 (all parts) and EMV
Contactless Interface Specification
[1]

It is acknowledged that next to this document there is also EMV Contactless Interface Specification

relevant for many PT devices; therefore this document is developed such that PT devices can comply

[1]

with the requirements of both EMV Contactless Interface Specification and this document.

7 Interoperability of PT devices and NFC mobile devices
7.1 Description of the “concept for interoperability”

The contactless interface for NFC mobile devices follows the implementation and test specifications of

[3] [4]

the NFC Forum as specified by the NFC Forum and referenced in GSMA TS.26 and TS.27 .

The ISO/IEC 14443 (all parts) contactless interface of PT devices is designed and tested according to

the rules defined in this document.

The concept for interoperability is established to synchronise the specifications for the contactless

interface of NFC mobile devices and those for the contactless interface of PT devices in order to:

— facilitate interoperability between NFC mobile devices and PT devices;
— avoid unnecessary test and certification effort.
[5] [6]

The NFC Forum conducted a comparison of NFC Analog Specification and NFC Digital Specification

with ISO/IEC 14443 (all parts) and ISO/IEC 10373-6. Procedures that support correlation between

results from tests according to NFC Forum specifications and those according to ISO/IEC 10373-6 have

been defined.

The correlation is used to translate test results from the NFC Forum’s terminology into ISO/IEC 10373-6’s

method for describing the relevant parameters. This is the foundation for the following characteristics

of the concept for interoperability:
a) Development of PT devices and NFC mobile devices

Despite the fact that different methods for describing the relevant parameters are used, this

document and the relevant implementation specifications from the NFC Forum can be synchronised.

By synchronising the implementations’ specifications, interoperability is integrated into the design

processes of NFC mobile devices and PT devices and makes it a common feature for both types of

devices.

ISO/IEC TS 24192-1:2021(E)
b) Test and certification of PT devices and NFC mobile devices

Based on the concept for interoperability it is possible to judge if an NFC mobile device that went

through NFC Forum testing is interoperable with a PT device that complies with the requirements

for ISO/IEC 14443 (all parts) set out in this document. Therefore, it is sufficient evidence of

interoperability to test and certify ISO/IEC 14443 (all parts) conformant PT devices according to

ISO/IEC TS 24192-2 and to test and certify NFC mobile devices according to NFC Forum’s test and

certification procedures.

The detailed methodology used to demonstrate the concept of interoperability between NFC Forum

compliant devices and ISO/IEC 14443 (all parts) compliant devices is described in Reference [8].

Table 1 summarizes how contactless communication can be ensured either via conformity testing

between PT readers and PT objects or via interoperability testing between PT devices and NFC mobile

devices.

7.2 References for implementation and test of NFC mobile devices

The applicable NFC Forum specifications for designing and testing the contactless communication of

NFC mobile devices are listed in the Bibliography (References [2] to [7]).

Conformance of NFC mobile devices to these specifications is a prerequisite to ensure interoperability

of NFC mobile devices with PT devices as presented in Table 1.
7.3 Limitations

Only parameters, parameter settings or modes of operations that are relevant for PT use cases have

been regarded and aligned with for both NFC mobile and PT devices. These use cases are described in

[2]

the STA document "Documentation of Use Cases for NFC Mobile Devices in Public Transport" .

The following parameters, settings or modes are currently not covered by the harmonization of

specifications according to the concept for interoperability described in 7.1:
a) communication bit rates higher than f /128 (~106 kbit/s);
b) peer-to-peer mode according to NFC Forum specifications;
c) ISO/IEC 18092 mode of communication;
d) ISO/IEC 15693-2 mode of communication.

8 Requirements and recommendations applicable to PT readers
8.1 General
8.1.1 Overview
8.2 and 8.3 define requirements; and 8.4 defines recommendations for PT readers.

The requirements and recommendations on PT readers are identified by a numbering format that reads

[Rdrnn] where nn is the number of the requirement or recommendation.
There are two categories of PT readers:
— IFM reader;
— common reader.

All implementation requirements and tests that are necessary to achieve interoperability between PT

readers and PT objects are mandatory for both PT reader categories.
8.1.2 IFM reader

The first category, the “IFM reader”, covers use cases where performances (i.e. operating distance,

transaction time, etc.) are key. As shown in Figure 1 and Figure 2, the IFM reader shall offer an operating

range that covers the full scope of range A and range B defined in 11.3.3.2 and 11.3.3.4 respectively. All

the test positions are defined in Table 3 and Table 4.

Position A1 of range A and Position B1 of range B may be at a different position on the IFM reader,

see 11.3.3.

ISO/IEC TS 24192-1:2021(E)
Figure 2 — Range B test positions for IFM reader
8.1.3 Common reader

The second category, the “common reader", is defined for scenarios that impose requirements on the

contactless interface such as minimization of cost or maximization of battery life of the PT reader.

These requirements have been derived from use cases from the following parts of the PT operator’s

system implementation which are described in the STA document “Documentation of Use Cases for NFC

[2]
Mobile Devices in Public Transport” :
a) sales infrastructure;
b) customer’s home infrastructure;
c) mobile inspection terminals.
Some requirements given in this document are adapted for common readers.

As shown in Figure 3, the common reader shall offer an operating range that covers a limited subset of

range A defined in 11.3.3.2. All the test positions are defined in Table 3.

8.2 General requirements

[Rdr1] The PT reader shall meet the requirements for PCD defined in the ISO/IEC 14443 (all parts) and

pass associated ISO/IEC 10373-6 test methods.

NOTE 1 The PT reader is tested against Reference PICC 1, Reference PICC 2 and Reference PICC 3 only,

corresponding to the mandatory PICC classes “Class 1”, “Class 2” and “Class 3”. No test is required with Reference

PICC 4, Reference PICC 5 and Reference PICC 6 corresponding to the optional PICC classes “Class 4”, “Class 5” and

“Class 6”.

NOTE 2 There are no particular restrictions to PT readers for accepting contactless objects using any value

for Application data field (Type B).
[1]

NOTE 3 EMV Contactless Interface Specification imposes that the extended ATQB option not be supported.

ISO/IEC 14443-3 considers that the support of this feature is optional.
[Rdr2] For IFM readers:

— In all range A test positions (see Figure 1), the IFM reader shall comply with all the [Rdr1]

requirements when tested with Reference PICC 1, Reference PICC 2 and Reference PICC 3.

— In all range B test positions (see Figure 2) when tested with Reference PICC 3, the IFM reader shall:

— comply with all the [Rdr1] requirements;
— provide a field strength of at least 2 A/m (rms).
[Rdr3] For common readers:

— In Position A1, Position A1,1, Position A1,2, Position A1,3, Position A1,4 and Position A2 (see

Figure 3), the common reader shall comply with all the [Rdr1] requirements when with Reference

PICC 1, Reference PICC 2 and Reference PICC 3.
— There are no requirements applicable to range B.

ISO/IEC TS 24192-1:2021(E)

NOTE 4 These minimum operating distance ranges are added as complementary requirements to

ISO/IEC 14443-2. Operating distance ranges A and B are defined in 11.3.

NOTE 5 The minimum field strength requirement in range B is set to anticipate future acceptance of objects of

optional classes “Class 4”, “Class 5” and “Class 6”.

[Rdr4] The PT reader shall use an AFI of '00' in at least one REQB/WUPB command in its polling

sequence.
8.3 Requirements on polling and recognizing contactless objects

This subclause defines the requirements on the polling sequence of contactless objects.

[1]

NOTE 1 EMV Contactless Interface Specification defines specific polling requirements which can impact the

transaction time.

[Rdr5] The time-to-detection of a Reference PICC requiring minimum SFGT (no SFGI or SFGI = 0) by the

PT reader shall be less than t = 250 ms. This remains a valid requirement regardless of the moment

detect

when the Reference PICC is placed within range A or B of the PT reader. The Reference PICC time-to-

detection is defined between the moment when the Reference PICC is placed into the field and the send-

out of the first I-block sent by the PT reader. The Reference PICC time-to-detection shall be the average

value measured on 10 consecutive measurements and shall be provided by the testing laboratory as

part of
...
