This part of ISO/IEC 7811 specifies characteristics for a high coercivity magnetic stripe (including any protective overlay) on an identification card, the encoding technique and coded character sets.
Coercivity influences many of the quantities specified in this part of lSO/IEC 7811 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 781 l-2.
For the testing of these card requirements refer to lSO/IEC 10373.
This part of lSO/IEC 7811 specifies the requirements for cards used for identification. It takes into consideration both human and machine aspects and states minimum requirements.
