Public transport - Communication between contactless readers and fare media - Part 1: Implementation requirements for ISO/IEC 14443

This document constitutes the 3rd edition of CEN/TS 16794 1. It sets out 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 series 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 the ISO/IEC 14443 series;
-   PT objects which are contactless fare media acting as a PICC contactless object based on the ISO/IEC 14443 series.
This edition addresses interoperability of consumer-market NFC mobile devices, compliant to NFC Forum specifications, with above mentioned PT devices, aligns with the 4th edition of the ISO/IEC 14443 series and maintains the possibility for PT readers to comply with the requirements from EMV Contactless Interface Specification [1] and the present document.
An interface–oriented test approach is used to evaluate the conformity of PT devices and is defined in CEN/TS 16794 2.
Application-to-application exchanges executed once contactless communication has been established at RF level fall outside the scope of this document. In line with the rules on independence between OSI protocol layers, this document works on the assumption that application-to-application exchanges are not contingent on the type of contactless communication established or the parameters used for the low-level protocol layers that serve as the platform for these application-to-application exchanges.

Javni prevoz - Komunikacija med brezkontaktnimi čitalniki/terminali in prevoznimi mediji - 1. del: Zahteve za izvajanje ISO/IEC 14443

Ta dokument predstavlja 3. izdajo standarda CEN/TS 16794 1. Določa tehnične zahteve, ki jih morajo izpolnjevati brezkontaktne naprave javnega prevoza (PT), da jim je omogočeno skupno delovanje s pomočjo brezkontaktnega komunikacijskega protokola skupine standardov ISO/IEC 14443.
Dokument se uporablja za naprave javnega prevoza:
– čitalnike javnega prevoza, ki so brezkontaktni terminali za prevozne medije in delujejo kot brezkontaktni čitalniki PCD na podlagi skupine standardov ISO/IEC 14443;
– predmete javnega prevoza, ki so brezkontaktni prevozni mediji, ki delujejo kot brezkontaktni predmet PICC na podlagi skupine standardov ISO/IEC 14443.
Ta izdaja obravnava interoperabilnost potrošniških mobilnih naprav NFC, ki so v skladu s specifikacijami foruma NFC, z zgoraj omenjenimi napravami javnega prevoza, je usklajena s četrto izdajo skupine standardov ISO/IEC 14443 in omogoča, da čitalniki javnega prevoza izpolnjujejo zahteve specifikacij brezkontaktnega vmesnika pri transakcijah EMV [1] in tega dokumenta.
Za ocenjevanje skladnosti naprav javnega prevoza se uporablja vmesniško usmerjen preskusni pristop, ki je opredeljen v standardu CEN/TS 16794 2.
Izmenjave med aplikacijami, ki so izvedene po vzpostavitvi brezkontaktne komunikacije na radiofrekvenčni stopnji, ne spadajo na področje uporabe tega dokumenta. V skladu s pravili o neodvisnosti med plastmi protokolov OSI ta dokument predpostavlja, da izmenjave med aplikacijami niso odvisne od vrste vzpostavljene brezkontaktne komunikacije ali parametrov, ki se uporabljajo za protokole nižjih plasti, ki služijo kot platforma za te izmenjave med aplikacijami.

1 Scope
rd
This document constitutes the 3 edition of CEN/TS 16794-1. It sets out 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 series (ISO/IEC 14443-1, ISO/IEC 14443-2, ISO/IEC 14443-3 and ISO/IEC 14443-4)
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 the ISO/IEC 14443 series;
— PT objects which are contactless fare media acting as a PICC contactless object based on the
ISO/IEC 14443 series.
This edition addresses interoperability of consumer-market NFC mobile devices, compliant to NFC
Forum specifications, with above mentioned PT devices, aligns with the 4th edition of the
ISO/IEC 14443 series and maintains the possibility for PT readers to comply with the requirements
from EMV Contactless Interface Specification and the present document.
An interface–oriented test approach is used to evaluate the conformity of PT devices and is defined in
CEN/TS 16794-2.
Application-to-application exchanges executed once contactless communication has been established at
RF level fall outside the scope of this document. In line with the rules on independence between OSI
protocol layers, this document works on the assumption that application-to-application exchanges are
not contingent on the type of contactless communication established or the parameters used for the
low-level protocol layers that serve as the platform for these application-to-application exchanges.

5 Conformance
Conformance to this document carries a number of requisites:
— For a PT reader, to meet all the [Rdrnn] requirements listed herein that are applicable according to
the applicant's stated implementation characteristics (ICS), under the test conditions stipulated in
Clause 11 and following the PCD test plan set out in CEN/TS 16794-2.
— For a PT object, to meet all the [Objnn] requirements listed herein that are applicable according to
the applicant's stated implementation characteristics (ICS), under the test conditions stipulated in
Clause 11 and following the PICC test plan set out in CEN/TS 16794-2.
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 CEN/TS 16794-1 is out of scope of this document.
6 Dual conformance of PT devices to the CEN/TS 16794 series and EMV
Contactless Interface Specification
In the current state of EMV Contactless Interface Specification and CEN/TS 16794 development, no
interoperability is warranted between EMV devices (compliant with EMV Contactless Interface
Specification) and PT devices (compliant with the CEN/TS 16794 series).
Consequently, when PT readers need to accept EMV media and PT objects, a dual conformance of PT
readers according to the CEN/TS 16794 series and EMV Contactless Interface Specification is required.
7

---------------------- Page: 9 ----------------------
SIST-TS CEN/TS 16794-1:2019
CEN/TS 16794-1:2019 (E)
Similarly, when PT objects need to be used with EMV payment terminal and PT readers, a dual
conformance of PT objects according to the CEN/TS 16794 series and EMV Contactless Interface
Specification is required.
EMV Contactless Interface Specification defines requirements that may be more restrictive than or
conflicting with the ones in the ISO/IEC 14443 series. When this is the case, some warnings are inserted
into the present document.
This document allows PT devices to comply with the requirements of EMV Contactless Interface
Specification and of CEN/TS 16794-1.
Table 1 summarizes how dual conformance of PT devices to the CEN/TS 16794 series and EMV
Contactless Interface Specification is managed.

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
the NFC Forum as specified by the NFC Forum and referenced in GSMA TS.26 and TS.27.
The ISO/IEC 14443 series conformant contactless interface of PT devices is designed and tested
according to the rules set out in this document.
The concept for interoperability was established to synchronize 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; and
— avoid unnecessary test and certification effort.
The NFC Forum conducted a comparison of NFC Forum Analog and Digital specifications with
ISO/IEC 14443 series 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.
8

---------------------- Page: 10 ----------------------
SIST-TS CEN/TS 16794-1:2019
CEN/TS 16794-1:2019 (E)
The correlation is used to translate test results from the NFC Forum’s terminology into the
ISO/IEC 10373-6 method for describing the relevant parameters. This is the foundation for the
following characteristics of the concept for interoperability:
1) 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
synchronized. The necessary alignment is conducted by a liaison between CEN TC278 and the NFC
Forum. By synchronizing 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.
2) 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 ISO/IEC 14443
requirements set out in this document. Therefore, it will be sufficient evidence of interoperability to
test and certify ISO/IEC 14443 conformant PT devices according to CEN/TS 16794-2 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 compliant devices is described in the NFC Forum™ document
describing the methodology used to demonstrate the concept of interoperability [4].
Table 2 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 Clause 2.
Conformance of NFC mobile devices to these specifications is a mandatory prerequisite to ensure
interoperability of NFC mobile devices with PT devices as presented in Table 2.

7.3 Limitations
Only parameters, parameter settings or modes of operations that are relevant for PT use cases have
been regarded and synchronized for both NFC mobile and PT devices. These use cases are described in
the STA document “Documentation of Use Cases for NFC Mobile Devices in Public Transport” [1].
The following parameters, settings or modes are currently not covered by the synchronization of
specifications according to the concept for interoperability described in 7.1:
1. communication bit rates higher than 106 kbit/s;
2. peer-to-peer mode according to NFC Forum specifications;
3. ISO/IEC 18092 mode of communication;
4. ISO/IEC 15693 mode of communication.
8 Requirements applicable to PT readers
8.1 General
This clause sets out the requirements applicable to PT readers so that they can read contactless
objects, i.e. PT objects or NFC mobile devices in card emulation mode. In addition, PT readers can also
comply with the requirements from EMV Contactless Interface Specification and the present document.
The requirements described in 8.3, 8.4 and 8.5 are normative and mandatory to achieve
interoperability.
The requirement described in 8.6 is informative only, hence not necessary to achieve interoperability.
The requirements on PT readers are identified by a numbering format that reads [Rdrnn] where nn is
the number of the requirement.
This clause does not set out the requirements applicable to consumer market NFC mobile devices which
follow NFC Forum specifications and certification.
8.2 Categories of PT reader
8.2.1 General
This document reflects that PT reader requirements depend on particular use cases. Those for mobile
devices are documented in the STA document “Documentation of Use Cases for NFC Mobile Devices in
Public Transport”.
Therefore, two categories of PT readers are defined:
— 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.
8.2.2 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 4 and Table 5.

CEN/TS 16794-1:2019 (E)
8.2.3 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 Mobile
Devices in Public Transport”:
a) sales infrastructure;
b) customer’s home infrastructure;
c) mobile inspection terminals.
Some requirements given in this specification 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 4.

Figure 3 — Range A test positions for Common reader
8.3 Normative requirements applicable to PT readers
[Rdr1] The PT reader shall meet the mandatory normative requirements for PCD defined in the
ISO/IEC 14443 series and associated ISO/IEC 10373-6 test methods standard.
NOTE 1 The PT reader is tested against the Reference PICCs 1, 2 and 3 only, corresponding to mandatory
classes 1, 2 and 3. No test is required with Reference PICCs 4, 5 and 6 corresponding to optional classes 4, 5 and 6.
