Note
The ISO Standard uses the terminology of Unused Encoded cards
and Returned Cards for New cards and Used cards respectively.
An ISO committee has defined requirements for High Coercivity Magnetic Stripes. The
document is undergoing a final public review before publication as a Standard. The basis of this
pending standard is for reader compatibility with the "low coercivity" Standard (ISO/IEC 7811-
2). Since the Encoded Card Tester only measures previously encoded cards and does not
perform any encoding (recording) functions, the Tester is transparent to whether the card has a
High Coercivity or a Low Coercivity magnetic stripe.
