标准简介：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 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.
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
should be 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.
NOTE 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
should not be intermixed or reconverted. The original design was made using the Imperial measurement system.
