Identification cards — Recording technique — Part 8: Magnetic stripe — Coercivity of 51,7 kA/m (650 Oe)
ISO/IEC 7811-8:2014 defines the characteristics for identification cards as defined in Clause 4 of this part of ISO/IEC 7811, and the use of such cards for international interchange. ISO/IEC 7811-8:2014 specifies requirements for a 51,7 kA/m (650 Oe) magnetic stripe (including any protective overlay) on an identification card. The encoding technique and coded character sets are not defined, however, the specifications of ISO/IEC 7811‑2 may be used. It takes into consideration both human and machine aspects and states minimum requirements. Coercivity influences many of the quantities specified in this part of ISO/IEC 7811. It has a nominal value of 51,7 kA/m (650 Oe), but is not itself specified. Exposure of the card to a magnetic field is likely to destroy the recorded data. ISO/IEC 7811-8:2014 provides criteria to which cards are to perform. No consideration is given within this International Standard to the amount of use, if any, experienced by the card prior to test. Failure to conform to specified criteria is negotiated between the involved parties. ISO/IEC 10373‑2 specifies the test procedures used to check cards against the parameters specified in this part of ISO/IEC 7811. Numeric values in the SI and/or Imperial measurement system in this part of ISO/IEC 7811 may have been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the two are not to be intermixed or reconverted. The original design was made using the Imperial measurement system.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. Draft International
Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies
casting a vote.
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.
ISO/IEC 7811 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, SC 17,
Cards and personal identification.
This second edition cancels and replaces the first edition (ISO/IEC 7811-8:2008), which has been
technically revised. Major changes from the first edition are as follows:
— 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.
ISO/IEC 7811 consists of the following parts, under general title Identification cards — Recording technique:
— Part 1: Embossing
— Part 2: Magnetic stripe — Low coercivity
— Part 6: Magnetic stripe — High coercivity
— Part 7: Magnetic stripe — High coercivity, high density
— Part 8: Magnetic stripe — Coercivity of 51,7 kA/m (650 Oe)
— Part 9: Tactile identifier mark

Introduction
This part of ISO/IEC 7811 is similar to ISO/IEC 7811-2, except that its higher coercivity requires higher
energy to encode the data. The user of ISO/IEC 7811-8 is encouraged to review the entire standard for
revisions and updates. The major differences from ISO/IEC 7811-2 are listed below.
— In terms of coercivity, this part of ISO/IEC 7811 media (51,7 kA/m, 650 Oe) is between ISO/IEC 7811-
2 (23,9 kA/m, 300 Oe) and ISO/IEC 7811-6 (minimum 199 kA/m, 2 500 Oe).
— The primary application for 51,7 kA/m (650 Oe) is for hotel guest room entry systems worldwide.
— For Table 1 values, this part of ISO/IEC 7811 specifies different values for I (6,5 FR) and I (8 FR).
min max
— Encoding techniques, specification, and error detection are not specified in this part of ISO/IEC 7811.
— Wherever possible, the same definitions, criteria, and test methods are used in ISO/IEC 7811-2,
ISO/IEC 7811-6, and this part of ISO/IEC 7811.
Notes in this part of ISO/IEC 7811 are only used for giving additional information intended to assist
understanding or use, and do not contain provisions or requirements to which it is necessary to conform
in order to be able to claim compliance with this part of ISO/IEC 7811.

INTERNATIONAL STANDARD ISO/IEC 7811-8:2014(E)
Identification cards — Recording technique —
Part 8:
Magnetic stripe — Coercivity of 51,7 kA/m (650 Oe)
1 Scope
This International Standard defines the characteristics for identification cards as defined in Clause 4 of
this part of ISO/IEC 7811, and the use of such cards for international interchange.
This part of ISO/IEC 7811 specifies requirements for a 51,7 kA/m (650 Oe) magnetic stripe (including
any protective overlay) on an identification card. The encoding technique and coded character sets are
not defined, however, the specifications of ISO/IEC 7811-2 may be used. It takes into consideration both
human and machine aspects and states minimum requirements.
Coercivity influences many of the quantities specified in this part of ISO/IEC 7811. It has a nominal
value of 51,7 kA/m (650 Oe), but is not itself specified. Exposure of the card to a magnetic field is likely
to destroy the recorded data.
This International Standard provides criteria to which cards are to perform. No consideration is given
within this International Standard to the amount of use, if any, experienced by the card prior to test.
Failure to conform to specified criteria is negotiated between the involved parties.
ISO/IEC 10373-2 specifies the test procedures used to check cards against the parameters specified in
this part of ISO/IEC 7811.
Numeric values in the SI and/or Imperial measurement system in this part of ISO/IEC 7811 may have
been rounded off and therefore are consistent with, but not exactly equal to, each other. Either system
may be used, but the two are not to be intermixed or reconverted. The original design was made using
the Imperial measurement system.
2 Conformance
A prerequisite for conformance with this part of ISO/IEC 7811 is conformance with ISO/IEC 7810.
An identification card is in conformance with this part of ISO/IEC 7811 if it meets all mandatory
requirements specified herein. Default values apply if no others are specified.
