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 accordance with the editorial rules of the ISO/
IEC Directives, Part 2 (see www.iso.org/directives or www.iec.ch/members_experts/refdocs).
ISO and IEC draw attention to the possibility that the implementation of this document may involve the
use of (a) patent(s). ISO and IEC take no position concerning the evidence, validity or applicability of any
claimed patent rights in respect thereof. As of the date of publication of this document, ISO and IEC had not
received notice of (a) patent(s) which may be required to implement this document. However, implementers
are cautioned that this may not represent the latest information, which may be obtained from the patent
database available at www.iso.org/patents and https://patents.iec.ch. ISO and IEC shall not be held
responsible for identifying any or all such patent rights.

This document was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology,
Subcommittee SC 31, Automatic identification and data capture techniques.
This fifth edition cancels and replaces the fourth edition (ISO/IEC 15434:2019), which has been technically
revised.
The main changes are as follows:
— format “14” has been assigned to data structured with JSON syntax (see 5.3.2.16 and 5.4.15);
— format “15” has been assigned to data containing an ISO/IEC 20248 verifiable data construct (see 5.3.2.17
and 5.4.16);
— Annex B has been added to provide examples of syntax used to encode data into high-capacity ADC media.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html and

Introduction
This document defines the manner in which data is transferred to high-capacity automatic data capture
(ADC) media from a supplier’s information system and the manner in which data is transferred to the
recipient’s information system. It does not define the internal data storage format for specific high-capacity
ADC media. This document does not specify the application of data structures provided by a specific data
syntax format. The application of the data structure may be specified by industry conventions.
Users of automatic identification and data capture (AIDC) techniques benefit by being able to receive data
in a standard form and by being able to provide data in a standard form. Low capacity ADC media, such as
linear bar code symbologies and optical character recognition, typically encode a single field of data. Most
applications of these technologies involve the encoding of a single field of data by the supplier of the medium
and the subsequent decoding of the data field by the recipient. Encoding single fields of data permits the
supplier to perform the encoding from a single field within the supplier’s information system. Decoding
single fields of data permits the recipient to input this data into a single field in the recipient’s information
system, in lieu of key entry.
High-capacity ADC media, such as two-dimensional symbols, RFID transponders, contact memories and
smart cards, encode multiple fields of data. These multiple fields are usually parsed by the recipient’s
information system and then mapped to specific fields of data in the recipient’s information system. This
document defines the syntax for high-capacity ADC media, so as to enable ADC users to utilize a single
mapping utility, regardless of which high-capacity ADC medium is employed.
The benefits of using high-capacity ADC media come with challenges. The ability to convey both data and
meaning (e.g. assuming an encoded serial number is "12345"; "12345" is the data and the understanding
"12345" is a serial number is the meaning) within a single technology has been executed differently by many
industries in a variety of ways. The widespread use of these different data and meaning formats has led to
an additional challenge of identifying which format is being used. To address this challenge, this document
assigns many of the data and meaning formats a unique two-digit number called a format indicator which
identifies the data structure for the encoded data. These format indicators enable a user to employ one or
more formats within a single high-capacity ADC media and accurately decode the data stream.
This document defines a syntax to indicate the message encoded in the high-capacity ADC media conforms to
this document. Its defined syntax also indicates which data format or formats are being used to provide data
and meaning. The purpose of the syntax is to provide a mechanism for an automated information system
consuming data through high-capacity ADC media to adaptively interpret and parse the data meaningfully.
