What it is

Magnetic-stripe Track 1 (ISO 7813): format code, PAN, cardholder name, expiry, service code, discretionary data.

Specification reference

Defined in ISO 8583:1987 (base). Card networks publish their own dialect tables (Visa BASE I / V.I.P., Mastercard CIS) that refine formats, lengths, and — for private-use elements — the entire layout. Always confirm against the interface specification you implement.
