ISO/IEC 7811 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 intemational interchange.This part of ISO/IEC 7811 specifies requirements for a high coercivity magnetic stripe (including any protectiveoverlay) on an identification card, the encoding technique and coded character sets. It takes into considerationboth human and machine aspects and states minimum requirements.Coercivity influences many of the quantities specified in this part of ISO/IEC 7811 but is not itself specified.The main characteristic of the high coercivity magnetic stripe is its improved resistance to erasure. This isachieved with minimal probability of damage to other magnetic stripes by contact while retaining readcompatibility 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 7811to the amount of use, if any, experienced by the card prior to test. Failure to conform to specified criteriashould be negotiated between the involved parties.ISO/IEC 10373-2 specifies the test procedures used to check cards against the parameters specified in thispart of ISO/IEC 7811.NOTENumeric values in the SI and/or Imperial measurement system in this part of ISO/IEC 7811 may have beenrounded off and therefore are consistent with, but not exactly equal to, each other. Either system may be used, but the twoshould not be intermixed or reconverted. The original design was made using the Imperial measurement system.
