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. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
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).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
Details of any patent rights identified during the development of the document will be in the Introduction
and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Information technology, Subcommittee SC
17, Cards and personal identification.
This second edition cancels and replaces the first edition (ISO/IEC 8484:2007) which has been technically
revised with the following changes:
— The primary standard cards held by Q-Card are used to calibrate the manufacture of secondary
reference cards. Other primary standard cards held by PTB and Card testing International (CTI) are
used as backup to replace cards held by Q-Card as they wear out.
— The supplier of secondary reference cards has changed from PTB to Q-Card. Wherever possible, the
terms and definitions, criteria and test methods have been taken from ISO/IEC 7811-2.
Most of the magnetic characteristics are based on ISO/IEC 7811. Because savingsbooks are generally
paper-based documents, some criteria and test methods have been taken from ISO/IEC 15457-2.
Notes in this International Standard are only used for giving additional information intended to assist in
the understanding or use of the International Standard and do not contain provisions or requirements to
which it is necessary to conform in order to be able to claim compliance with this International Standard.
NOTE Numbers for signal amplitude and flux transition spacing variation are taken from ISO/IEC 7811-2 and
ISO/IEC 15457-2 and are based on testing performed on sample passbooks at two test facilities.

INTERNATIONAL STANDARD ISO/IEC 8484:2014(E)
Information technology — Magnetic stripes on
savingsbooks
1 Scope
This International Standard specifies the characteristics and location of a magnetic stripe on a
savingsbook as defined in Clause 4 and the use of such savingsbooks for international interchange.
Compatibility with international interchange systems is provided through the requirements of this
International Standard, enabling a savingsbook with a magnetic stripe to be read and possibly encoded
in a device that is compatible with reading identification cards used in international interchange.
This International Standard specifies requirements for a magnetic stripe (including any protective
overlay) on a savingsbook, the encoding technique, and coded character sets. It also specifies the
characteristics of the savingsbook cover such as stiffness, minimum size, surface irregularities,
roughness, and interaction between the cover material and the magnetic stripe. It takes into consideration
both human and machine aspects and states minimum requirements.
Coercivity influences many of the quantities specified in this International Standard but is not itself
specified. Exposure of the savingsbook to a magnetic field is likely to destroy the recorded data.
This International Standard defines performance criteria for savingsbooks. No consideration is given
within this International Standard to the amount of use, if any, experienced by the savingsbook prior to
test. Failure to conform to specified criteria will be negotiated between the involved parties.
ISO/IEC 10373-2 specifies the test procedures used to check savingsbooks against the parameters
specified in this International Standard. References in the test method to cards refer to savingsbooks.
NOTE 1 Numeric values in the SI and/or Imperial measurement system in this International Standard might
have been rounded off and are therefore consistent with, but not exactly equal to, each other. Either system can
be used, but the two are not be intermixed or reconverted. The original design was made using the Imperial
measurement system.
NOTE 2 National systems can use different specifications, such as DIN, as well as proprietary specifications for
closed systems.
2 Conformance
A savingsbook is in conformance with this International Standard if it meets all mandatory requirements
specified herein. Default values apply if no others are specified.
