ISO/IEC 7816-6:2023(E)
Introduction
ISO/IEC 7816 is a series of International Standards specifying integrated circuit cards and the use of
such cards for interchange. These cards are identification cards intended for information exchange
negotiated between the outside world and the integrated circuit in the card. As a result of an information
exchange, the card delivers information (computation result, stored data), and/or modifies its content
(data storage, event memorization).
— Five parts are specific to cards with galvanic contacts and three of them specify electrical interfaces.
— ISO/IEC 7816-1 specifies physical characteristics for cards with contacts.
— ISO/IEC 7816-2 specifies dimensions and location of the contacts.
— ISO/IEC 7816-3 specifies electrical interface and transmission protocols for asynchronous
cards.
— ISO/IEC 7816-10 specifies electrical interface and answer to reset for synchronous cards.
— ISO/IEC 7816-12 specifies electrical interface and operating procedures for USB cards.
— All the other parts are independent from the physical interface technology. They apply to cards
accessed by contacts and/or by radio frequency.
— ISO/IEC 7816-4 specifies organization, security and commands for interchange.
— ISO/IEC 7816-5 specifies registration of application providers.
— ISO/IEC 7816-6 specifies interindustry data elements for interchange.
— ISO/IEC 7816-7 specifies commands for structured card query language.
— ISO/IEC 7816-8 specifies commands for security operations.
— ISO/IEC 7816-9 specifies commands for card management.
— ISO/IEC 7816-11 specifies personal verification through biometric methods.
— ISO/IEC 7816-13 specifies commands for handling the life cycle of applications.
— ISO/IEC 7816-15 specifies cryptographic information application.
The ISO/IEC 10536 series specifies access by close coupling. The ISO/IEC 14443 series and the
ISO/IEC 15693 series specify access by radio frequency. Such cards are also known as contactless cards.

Part 6:
Interindustry data elements for interchange
1 Scope
This document specifies directly or by reference, data elements, including composite data elements that
are applicable to interindustry interchange.
It identifies the following characteristics of each data element:
— identifier;
— name;
— description and reference;
— format and coding (if not available in other ISO standards or parts of the ISO/IEC 7816 series).
The layout of each data element is described as seen at the interface between the interface device and
the card.
This document provides the definition of data elements without consideration of any restrictions on the
usage of the data elements.
It does not cover the internal implementation within the card and/or the outside world. With the
exception of login data objects (6.5), only application class tags are eligible in this document.
When using an interindustry template, an application is allowed to nest context-specific class tags (see
ISO/IEC 7816-4) under such a template unless it is previously marked as reserved for future use by ISO/
IEC JTC 1/SC 17.

5 Maintenance of interindustry data objects
It is the intention that every interindustry data object, specified at the time of publication, should
be listed in this document. To allow the introduction, deletion, or amendment of any data object, the
following procedures shall be adopted:
— Interindustry data objects from the ISO/IEC 7816 series — Following the publication of any part
of the ISO/IEC 7816 series that introduces new data objects, these data objects will be incorporated
into this document at the next revision.
— Interindustry data objects from other standards — For such data objects, an amendment to this
document will be required and this will be subject to the normal ISO/IEC JTC 1 voting procedures.
Following a successful ballot, the data objects will be incorporated into this document.
— Allocation authority — Once an application class tag is allocated to a norm as described above,
this norm becomes the allocation authority for all context-specific data objects it endorses and
encapsulates under the aforementioned tag.
6 Specific interindustry data elements
6.1 Name of an individual
Referenced by tag ‘5B’, this interindustry data element consists of up to 39 bytes; each byte is a character
as defined in ISO/IEC 7501-1. The data element consists of surname, i.e. family name, given name(s), i.e.
forename(s), name suffix, e.g. Jr., number, and filler(s), all coded according to ISO/IEC 8859-1.
National languages with non-Latin characters shall be transliterated or transcribed into the Latin
alphabet using the appropriate International Standard. In cases where names cannot be shown in full
or a special alphabet is needed or the transliteration or transcription is not sufficient, the qualified
name template should be used.
6.2 Proprietary login data
Referenced by tag ‘5E’, this interindustry data element consists of login data with proprietary structures
not specified in the ISO/IEC 7816 series.

ISO/IEC 7816-6:2023(E)
6.3 Magnetic stripe data
The coding of the magnetic stripe data is as follows:
— referenced respectively by tags ‘5F21’, ‘5F22’ and ‘5F23’, these interindustry data elements shall code
card tracks 1, 2 and 3. Such a tag shall be used when the data element is identical to the data coded
on the corresponding track on the magnetic stripe of the card in accordance with ISO/IEC 7813 and
ISO/IEC 4909;
— referenced respectively by tags ‘56’, ‘57’ and ‘58’, these interindustry data elements shall code
application tracks 1, 2 and 3. Such a tag shall be used when, while formatted according to ISO/IEC 7813
and ISO/IEC 4909, the data element may differ from the data coded on the corresponding track of
the magnetic stripe of the card.
6.4 PIN usage policy
Referenced by tag ‘5F2F’, this interindustry data element shall consist of two bytes. It lists the tests
the terminal shall perform in order to determine whether a PIN (personal identification number) is
applicable to the current transaction, and, therefore, whether the terminal should prompt for the PIN. If
set to one, bit 8 of the first byte specifies that a PIN applies to this application and the terminal should
prompt for the PIN. The meaning of the other fifteen bits is application-dependent. If all bits are set to
zero, then the terminal should not prompt for the PIN. If bit 8 of the first byte is set to one or if any test
implies a PIN, but the PIN cannot be presented, then the action to take is application-dependent.
6.5 Login template
Referenced by tag ‘6A’, this interindustry template shall consist of one or more primitive data objects.
Within the login template, the context-specific class (first byte in the range ‘80’ to ‘BF’) is reserved
for login data objects, such as qualifiers, numbers, texts and delay indicators, as listed in Table 1 and
specified hereafter.
Table 1 — Login data objects
Tag (hex) Meaning
6A Interindustry template for nesting login data objects with the following tags
80 Qualifier
81 Number
82 Text
83, 84 Delay indicators
In this context, ISO/IEC JTC 1/SC 17 reserves any other data object of the context-specific class (first byte
from ‘80’ to ‘BF’)
— Qualifier — Referenced by tag ‘80’ in a login template, this data element shall consist of one to
nine bytes: A mandatory first byte coding a rank, followed by up to eight optional bytes coding a
mnemonic. It shall qualify the subsequent objects in the template, until the next qualifier, if any.
— The rank is a number from zero to 255. If two or more qualifiers have the same rank within the
same context, then only the set of objects qualified by the most recent one is valid.
— The mnemonic is a string of up to eight bytes consisting of 7-bit characters (bit 8 set to 0, see
ISO/IEC 646) to display at the man-machine interface.
— Number — Referenced by tag ‘81’ in a login template, this data element shall consist of an even
number of quartets where each quartet codes one character for representing a telephone number
according to Table 2.
— Text — Referenced by tag ‘82’ in a login template, this data element shall consist of one or more
bytes where each byte codes one character. Bit 8 sets the difference between data characters (bit 8

---------------------- Page: 9 ----------------------
ISO/IEC 7816-6:2023(E)
set to zero) and control characters (bit 8 set to one). The byte string consists of one or more strings
of data characters (7-bit character, see ISO/IEC 646) separated by strings of control characters. The
following control characters are defined.
— ‘80’ — A message has to be received before sending the next character.
— ‘C0’ — A modulation has to be present before sending the next character.
— ‘8X’ — X characters have to be received in echo before waiting for a message.
— Delay indicators — Referenced by tag ‘83’ or ‘84’ in a login template, this data element shall consist
of one byte as specified in Table 3.
— When present, a delay indicator data object with tag ‘83’ fixes the time for detecting an end of
message. The default value shall be two seconds.
— When present, a delay indicator data object with tag ‘84’ fixes the time for detecting an absence
of response. The default value shall be sixty seconds.

be formatted as defined in ISO/IEC 10918-1, unless otherwise specified and/or requested by an
authority.
— Cardholder handwritten signature image — referenced by tag ‘5F43’, this interindustry data
element shall be formatted as defined in ISO/IEC 11544 unless otherwise specified and/or requested
by an authority.
The use of this interindustry data object should be associated with appropriate security measures.
Further information on personal verification through biometric methods may be found in
ISO/IEC 7816-11.
6.8 Application image template
Referenced by tag ‘6D’, this interindustry template shall contain at least an application image (tag
‘5F44’), i.e. an icon or a logo related to the application. It may also contain an authority indicator (see
ISO/IEC 7816-4) identifying the authority responsible for the data format of the application image. In
the absence of authority indicator, the format shall be as defined in ISO/IEC 10918-1.
6.9 Display control template
Referenced by tag ‘7F20’, this interindustry template may contain one or more data objects, the value of
which, either directly or indirectly through templates, is not intended to be displayed and should only
be used, when relevant, for processing of transmission.
7 Identification of integrated circuit manufacturers
7.1 General
This clause specifies
— a numbering system for integrated circuit manufacturer identifiers, and
— rules for registration of integrated circuit manufacturers and rules for assignment of identifiers
to identify manufacturers of integrated circuits to be embedded in contact and/or contactless
integrated circuits cards. The assigned values of the integrated circuit manufacturer identifiers will
form the register.
7.2 Identifier
The identifier is referenced by tag ‘5F4D’. It may be present in pre-issuing data (compact header ‘6Y’ in
the historical bytes and interindustry tag ‘46’ in EF .ATR/ INFO) on a proprietary basis.
NOTE Tag '5F4B' for referencing identifiers is deprecated in the ISO/IEC 7816 series, because two different
definitions existed within that series.
6
  © ISO/IEC 2023 – All rights reserved

---------------------- Page: 11 ----------------------
ISO/IEC 7816-6:2023(E)
The identifier consists of one or more byte. The identifier shall be coded according to Table 4 and
Table 5.
Table 4 — First identifier byte
Value Meaning
‘00’ No information given
‘01’ . ‘7E’ Reserved for the register of one byte identifier
‘7F’, ‘80’ Reserved for future use by ISO/IEC JTC 1/SC 17
‘81’ . ‘FE’ Proprietary
‘FF’ Reserved for register of identifiers with more than one byte, at least one
subsequent identifier byte follows, see Table 5
Table 5 — Subsequent identifier bytes
Value Meaning
If bit b8 equals 1: Another identifier byte follows.
If bit b8 equals 0: Last byte of identifier.
‘xx’
Bits b7 to b1 contain arbitrary values.
The integrated circuit manufacturer identifier is represented by the sequence of bytes
starting with ‘FF’ up to and including the last byte of the sequence.
7.3 Rules for assignment
The name and contact information of the maintenance agency for this integrated circuit manufacturer
identifiers can be found at www .iso .org/ maintenance _agencies. Such identifiers will be assigned
according to the following rules:
a) the assignment is made upon request from any integrated circuit manufacturer or any interested
party;
b) the form contained in Annex A should be used to request an assignment;
c) a single number shall be assigned to each manufacturer;
d) the last assigned number shall be incremented by one to build the newly assigned number (i.e. only
if all available n-byte values have been assigned, the assignment of (n+1)-byte identifier shall start);
NOTE 1 ‘FF00’ is the first two byte identifier. ‘FF7F’ is the last two byte identifier. ‘FF8000’ is the first three
byte identifier. ‘FFFF7F’ is the last three byte identifier. Incrementing the identifier value ‘FF807F’ by one leads
to the value ‘FF8100’.
NOTE 2 Between 2007 and 2018 an average of approximately six identifiers have been assigned per year.
Keeping up that rate it follows that the first two byte identifier is expected soon, in 2040 the first three byte IC
manufacturer is expected and 2700 years later the first four byte identifier is expected. If the rate of assigning
increases from six per year to one per day then the first four byte identifier is expected in approximately the year
2060.
WARNING — As pointed out by NOTE 2 it is expected that the length of assigned integrated
circuit manufacturer identifier possibly increases from one byte to two bytes soon.
8 Interchange profile
The specification of data objects associated with the interchange profile of the card (e.g. available
authentication methods and security functions) may be further detailed in future parts of the
ISO/IEC 7816 series. Table 6 shows interindustry data objects reserved for interchange profile.
