Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work.
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 different types of document should be noted. This document was drafted in

Introduction
The ISO/IEC 7816 series of standards specifies 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 in the ISO/IEC 7816 series 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 operation procedures for USB cards.
All of the other parts in the ISO/IEC 7816 series 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 (this document) 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".

5 Commands for biometric verification and its related processes
5.1 General
PERFORM BIOMETRIC OPERATION (PBO) command defined in 5.4 describes biometric operations for
enrolment (storage of biometric data in an ICC) and verification (comparison of biometric data with
reference data stored in the ICC). Both storage and comparison of biometric data can also be achieved
by use of commands defined in ISO/IEC 7816-4 (e.g. PUT DATA, UPDATE BINARY for storage, VERIFY for
comparison).
PBO command also supports ACBio defined in ISO/IEC 24761 (see 6.2).
5.2 Commands for a biometric static verification process
The commands to be used for a static verification process (see an example shown in Annex A) shall
be VERIFY command as specified in ISO/IEC 7816-4 or PERFORM BIOMETRIC OPERATION (PBO) command
with relevant operations, e.g. comparison of biometric probe as specified in 5.4. When VERIFY command
is used and the biometric data is externally-captured, the command shall contain the biometric data
3

---------------------- Page: 9 ----------------------
ISO/IEC 7816-11:2022(E)
as biometric probe to be compared in its data field, encoded as defined in 7.1 and 7.2. The biometric
algorithm identifier shall be either
— implicitly known,
— defined in a security environment (SE) within a control reference template for authentication (AT),
— defined in a command data within a biometric information template (see ISO/IEC 24787), or
— defined in a command data within a control reference template for authentication.
The biometric reference qualifier can be either
— defined in a SE within control reference template for authentication,
— defined in parameter P2 of VERIFY or PBO command,
— defined in a command data within a biometric information template (see 7.1),
— defined in a command data within a biometric data template (see 7.2), or
— defined in a command data within a control reference template for authentication.
The biometric probe can be encoded as BER-TLV data object (see Table 11). It can be recorded in a
biometric information template (see Table 8 and Table 9) or a biometric information template group
template (see Table 10).
Biometric data captured either in ICC or out of ICC can be compared. In the case of comparing internally-
captured biometric probe, feedback mechanism specified in ISO/IEC 17839-3 with the PBO operations
in 5.4.6 should be implemented.
5.3 Commands for a biometric dynamic verification process
To get a challenge to which a user response is required (see examples shown in Annex A), GET CHALLENGE
command defined in ISO/IEC 7816-4 or PBO command defined in 5.4 shall be used.
The type of challenge in a biometric verification process, e.g. a phrase for voiceprint or a phrase for
keystroke, depends on the biometric algorithm.
If the challenge is requested using GET CHALLENGE command, the P1 of the command shall identify the
biometric algorithm. As specified in ISO/IEC 7816-4, the P1 set to '00' means that no information is
given, i.e. the biometric algorithm is known before issuing the command.
If the challenge is requested using PBO command, the biometric algorithm shall be either
— implicitly known, or
— defined in a SE within control reference template for authentication.
Alternatively, the respective algorithm can be selected using MSE command (e.g. SET option with AT,
usage qualifier DO and algorithm reference DO in the command data field).
After receiving a biometric challenge, EXTERNAL AUTHENTICATE command or PBO command shall be sent
to the ICC. The command data field conveys the relevant biometric probe.
5.4 PERFORM BIOMETRIC OPERATION command
5.4.1 General definition of PBO command
One or more PBO command(s) can be used for biometric verification and its related processes. It initiates
various kinds of biometric operations and other relevant operations, in accordance with the value
indicated in P1.

NOTE ISO/IEC 7816-4 defines INS = '2E' and '2F' for PBO command but this document defines '2E' only, and '2F' is
reserved for future extension.
In Table 1, P1 indicates single operation related to biometrics. In Table 2, P2 qualifies the biometric
reference in the same manner as for basic security handling command specified in ISO/IEC 7816-4.

PBO command can be preceded by MSE command in order to set appropriate parameters. For example,
MSE command set a control reference template valid for authentication (AT) to a SE. When PBO command
executes, this SE can convey an indication of biometric user authentication with qualifier of its biometric
reference.
