ANSI ISO IEC-15457-2-2001 pdf download Identification cards — Thin flexible cards — Part 2: Magnetic recording techniques
1 Scope
Thin flexible cards, the subject of this International Standard, are used to automate the controls for access to goods or services such as mass transit, highway toll systems, car parks, vouchers, stored value, etc.
For these applications, data can be written and/or read by machines using various recording techniques such as magnetic stripe, optical character recognition (OCR), bar code, etc.
This part of ISO/IEC 15457 specifies the magnetic stripe and encoding characteristics of thin flexible cards at two points in the card life cycle:
1. at the point of loading into the card issuing equipment;
2. at the point of issue to the public.
Guidance concerning the storage and usage of finished cards (including magnetic stripe cards) under various environmental conditions is given in ISO/IEC 15457-1.

3 Terms and definitions
For the purposes of this part of ISO/IEC 15457, the terms and definitions given in ISO/IEC 15457-1 and the following apply.
3.1
track
area of stripe surface occupied by the data encoded by a single channel of the magnetic recording write/read interface
3.2
central stripe
stripe centred on the widthwise axis of the card
3.3
lateral stripe
any widthwise stripe which is not centred on the widthwise axis of the card
3.4
re-usable card
durable card able to be recovered from the field (generally by automatic equipment operation) and re-issued
3.5
unused, unencoded card
card possessing all the components required for its intended purpose that has not been subjected to any personalization or testing operation and that has been stored in a clean environment with no more than 48 hour exposure to daylight at temperatures between 5 ºC and 30 ºC and humidity between 10 % and 90 % without experiencing thermal shock
