About status words
A smart card ends every response APDU with two bytes — SW1 SW2 — that say what happened. 9000 is the universal “OK”. The 6XYY range covers warnings (62/63), state errors (64/65), wrong-length (67), command-not-allowed (69), wrong-parameters (6A), and proprietary (6F). The full table lives in ISO/IEC 7816-4, with extensions in GlobalPlatform and per-application standards.
