Public transport - Communication between contactless readers and fare media - Part 1: Implementation requirements for ISO/IEC 14443
This Technical Specification constitutes the 2nd 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 standard contactless communications protocol.
This Technical Specification applies to PT devices:
PT readers which are contactless fare management system terminals acting as a PCD contactless reader based on ISO/IEC 14443 standard series;
PT objects which are contactless fare media acting as a PICC contactless object based on ISO/IEC 14443 standard series.
This new version also addresses interoperability of consumer-market NFC mobile devices, compliant to NFC Forum specifications, with above mentioned PT devices.
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 independency 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 by 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 9 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 9 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 Interoperability of PT devices and NFC mobile devices
6.1 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 conformant contactless interface of PT devices is designed and tested according to
the rules set out in this technical specification.
The concept for interoperability was 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:
— ensure the interoperablitity 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 and ISO/IEC 10373-6 standards. Procedures that support correlation between results
from tests according to NFC Forum specifications and those according to ISO/IEC 10373-6 have been
defined.

---------------------- Page: 8 ----------------------
SIST-TS CEN/TS 16794-1:2017
CEN/TS 16794-1:2017 (E)
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:
1. Development of PT devices and NFC mobile devices
Despite the fact that different methods for describing the relevant parameters are used, this technical
specification and the relevant implementation specifications from the NFC Forum can be synchronised.
The necessary alignment is conducted by a liaison between CEN TC278 and the NFC Forum. By
synchronising the implementations’ specifications, interoperability is integrated in 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 interoperatbility between NFC Forum
compliant devices and ISO/IEC 14443 compliant devices is described in [NFC Forum™ - Document
describing the methodology used to demonstrate the concept of interoperability].
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.

6.3 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" [2].
The following parameters, settings or modes are currently not covered by the synchronisation of
specifications according to the concept for interoperability described in 6.1:
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.
7 Requirements applicable to PT readers
7.1 General
This clause sets out the requirements applicable to PT readers.
Requirements described in 7.3, 7.4 and 7.5 are normative and mandatory to achieve interoperability.
Requirement described in 7.6 is informative only, hence not necessary to achieve interoperability.
Requirements on PT readers are identified by a numbering format that reads [Rdrnn] where nn is the
number of the requirement.
PT readers shall be able to read contactless objects, i.e. PT objects or NFC mobile devices in card
emulation mode.
This clause does not set out the requirements applicable to consumer market NFC mobile devices which
follow NFC Forum specifications and certification.
7.2 Categories of PT reader
This Technical Specification reflects that PT readerOT 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 introduced:
— The first category, the “IFM reader”, covers use cases where performance (i.e. operating distance,
transaction time, etc) is key.
— 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.

---------------------- Page: 10 ----------------------
SIST-TS CEN/TS 16794-1:2017
CEN/TS 16794-1:2017 (E)
Some requirements given in this specification are adapted for Common readers.
There is no compromise against the cost of interoperability as all implementation requirements and
tests that are necessary to achieve interoperability between PT readers and PT objects are mandatory
for both PT reader categories.
7.3 Normative requirements applicable to PT readers
[Rdr1] The PT reader shall meet the mandatory normative requirements for PCD defined in the
ISO/IEC 14443 standard 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.
NOTE 2 There are no particular restrictions to PT readers for accepting contactless objects using the UID
values (Type A) or PUPI values (Type B) stipulated in the standard, including random UID/PUPI values.
NOTE 3 There are no particular restrictions to PT readers for accepting contactless objects using any value for
Application data field (Type B).
EMV Contactless Specifications for Payment Systems — Book D imposes that the extended ATQB option
shall not be supported. ISO/IEC 14443-3 considers that the support of this feature is optional.
NOTE 4 This document makes it possible for the PT reader to accept a broad spectrum of contactless objects,
without distinction between form factors, but not smaller than Class 3, such as: contactless smartcards in ID-1
format (as defined in ISO/IEC 7810), contactless tickets, contactless USB keys and NFC mobile devices, or any
other contactless fare media that is a PICC and is in conformance with the requirements stipulated in this
document.
7.4 Specific requirements applicable to PT readers
[Rdr2] All the [Rdr1] requirements tested with the Reference PICCs 1, 2 and 3 shall be complied with
within the operating distance range A.
For Common readers, the range A required is limited to positions A1 to A2. If those positions cannot be
applied, because e.g. the fare media object shall be inserted into a card slot, a single position needs to be
defined by the manufacturer of the Common reader and tested accordingly. This single position shall be
either marked in such way that a user can clearly position his contactless object in this position or the
mechanical construction shall control the positioning of the contactless object in this position.
[Rdr3] When tested with Reference PICC 3 all the [Rdr1] requirements tested shall be complied with
within the operating distance range B. In addition, the PT reader shall provide a field strength of at least
2 A/m on all positions in this range B.
For Common readers, the range B required is limited to positions B1 to B2. If those positions cannot be
applied, because e.g. the fare media object shall be inserted into a card slot, a single position needs to be
defined by the manufacturer of the Common reader and tested accordingly. This single position shall be
either marked in such way that a user can clearly position his contactless object in this position or the
mechanical construction shall control the positioning of the contactless object in this position.
NOTE 1 These minimum operating distance ranges are added as complementary requirements to
ISO/IEC 14443-2. Operating distance ranges A and B are defined in 9.2.3.
NOTE 2 The minimum field strength requirement in range B is necessary to ensure the interoperability with
NFC mobile devices with antenna smaller than Class 3 which are compliant with NFCForum-TS-Analog-2.0
specification. A convergence with ISO/IEC 14443 minimum field strength value (to 1,5 A/m) is anticipated in a
future edition of this document.
[Rdr4] The PT reader shall use an AFI of 00h (applicable to Type B only).

---------------------- Page: 11 ----------------------
SIST-TS CEN/TS 16794-1:2017
CEN/TS 16794-1:2017 (E)
[Rdr5] The PT reader shall comply with ISO/IEC 14443 recommendations on reception of bits and
values reserved for future use.
NOTE 3 This requirement is intended to offer future proofed implementation that will allow the same
behaviour to remain valid when new options in the ISO/IEC 14443 standard series use any of the currently RFU
bits and/or values.
7.5 Requirements on polling and recognizing contactless objects
This subclause describes the “listen” strategy for polling contactless objects found present in the
operational field but does not address how they are handled once detected.
EMV Contactless Specifications for Payment Systems — Book D stipulates that for EMVCo L1
certification, once a contactless object has been detected, polling shall continue for the other RF type
and possible other contactless modulation schemes, codings and protocols on the same carrier
frequency that the PT reader supports before opening a dialogue with the object first detected. This
constraint slows the all-round transaction time, and consequently certain transport networks may
prefer a response behaviour wherein the first object detected gets immediately treated rather than
keep their terminal eligible for EMVCo L1 certification and thereby eligible for accepting payment cards.
[Rdr6] The time-to-detection of a Reference PICC requiring minimum SFGT (no SFGI or SFGI = 0) by
= 250 ms. This remains a valid requirement regardless of the
the PT reader shall be less than tdetect
moment 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 1 For PT readers that don't keep their field continuously active, the Reference PICC time-to-detection is
counted from the moment when the field is started and assumes that the PICC is already in the operating volume.
NOTE 2 While complying with the full set of requirements stipulated in ISO/IEC 14443-3 using the commands
of (REQA and/or WUPA) and of (REQB and/or WUPB) specified in ISO/IEC 14443-3, the polling sequence may
also poll for other objects non compliant with ISO/IEC 14443-3 using non ISO/IEC 14443-3 frame coding.
NOTE 3 In cases where objects non compliant with ISO/IEC 14443-3 are also polled for, it is possible to extend
the polling window for a given type to longer times (up to the maximum time to detection defined in [Rdr6])
rather than go for performance speeds. This application-layer option to extend the polling time for a different type
may be dependent on the number of cards of each type deployed locally at street-level.
When inserting field shut-offs in the polling sequence, the PT reader should take care that contactless
objects using a random identifier will respond with a different identifier and therefore should not
consider such an object as two different objects.
When getting no response from a contactless object despite error detection and recovery defined in
ISO/IEC 14443-4, PT readers not using any field shut-off in their polling sequence should use a field
shut-off to put the silent contactless object in IDLE state, allowing it to receive and answer request
commands without need to manually
