ISO/IEC 7811-6:2018 pdf download – Identification cards — Recording technique — Part 6: Magnetic stripe: High coercivity.
1 Scope ISO/IEC 7811 defines the characteristics for identification cards as defined in Clause 3 of this document and the use of such cards for international interchange. This document specifies requirements for a high coercivity magnetic stripe (including any protective overlay) on an identification card, the encoding technique and coded character sets. It takes into consideration both human and machine aspects and states minimum requirements. Coercivity influences many of the quantities specified in this document but is not itself specified. The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure. This is achieved with minimal probability of damage to other magnetic stripes by contact while retaining read compatibility with magnetic stripes as defined in ISO/IEC 7811-2. ISO/IEC 7811 provides criteria to which cards are to perform. No consideration is given within ISO/ IEC 7811 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 document. NOTE Numeric values in the SI and/or Imperial measurement system in this document may have been rounded off and are consistent with, but not exactly equal to each other. Using either system is correct but intermixing or reconverting values can result in errors. The original design was made using the Imperial measurement system.

ISO and IEC maintain terminological databases for use in standardization at the following addresses: — IEC Electropedia: available at http: //www .electropedia .org/ — ISO Online browsing platform: available at http: //www .iso .org/obp 3.1 primary standard set of reference cards established by the Physikalisch-Technische Bundesanstalt (PTB) and maintained by PTB, Q-Card, and Card Testing International secretariat that represent the values of U R and I R designated RM7811-6 3.2 secondary standard reference card designated RM7811-6 that is related to the primary standard as stated in the calibration certificate supplied with each card Note 1 to entry: Secondary standards can be ordered from Q-Card, 301 Reagan Street, Sunbury, PA 17801, USA. The source of secondary standards will be maintained at least until 2018. 3.3 unused un-encoded card card possessing all the components required for its intended purpose, which has not been subjected to any personalization or testing operation, and which has been stored in a clean environment with no more than 48 h exposure to daylight and at temperatures between 5 °C and 30 °C and humidity between 10 % and 90 % without experiencing thermal shock 3.4 unused encoded card card according to 3.3 that has only been encoded with all the data (magnetic, embossing, electronic, etc) required for its intended purpose 3.5 returned card card according to 3.4 after it has been issued to the card holder and returned for the purpose of testing 3.6 flux transition location of the greatest rate of change with distance of the magnetisation 3.7 reference current I R minimum recorded current amplitude under the given test conditions that causes, on the reference card, a readback signal amplitude equal to 80 % of the reference signal amplitude U R, at a density of 8 flux transitions per millimetre (200 flux transitions per inch) as shown in Figure 6.
