ISO/IEC 7811 Identification cards — Recording technique is a set of nine (7811-1 to 7811-9) standards describing the recording technique on identification cards.
It comprises:
- "Part 1": Embossing
- "Part 2": Magnetic stripe — Low coercivity
- "Part 3": Location of embossed characters on ID-1 cards
Part 3 is already withdrawn and revised by Part 1. - "Part 4": Location of read-only magnetic tracks — Tracks 1 and 2
Part 4 is already withdrawn and revised by Part 2. - "Part 5": Location of read-write magnetic track — Track 3
Part 5 is already withdrawn and revised by Part 2. - "Part 6": Magnetic stripe — High coercivity
- "Part 7": Magnetic stripe — High coercivity, high density
Allows capacity 10 times that of a card conforming to Part 6. - "Part 8": Magnetic stripe -- Coercivity of 51,7 kA/m (650 Oe)
(including any protective overlay) - "Part 9": Tactile identifier mark
Specifies the physical characteristics of a tactile identifier mark used by visually impaired card holders to distinguish their cards.
