APDU Response Codes

Look up ISO/IEC 7816-4 APDU status words (SW1 SW2) such as 9000, 6A82 or 6985 — with category, description and where each value is defined (ISO, SIM/UICC, DESFire, MULTOS or card-OS specific). Paste a status word to decode it instantly.

Follows ISO/IEC 7816-42020·verified Oct 2026· double-checked Oct 2026— interindustry SW1-SW2 match OpenSC, pyscard and osmocom (6287/6340 flagged as 2013+ only); SIM/UICC per GSM 11.11 / ETSI TS 102 221 (osmocom), DESFire per libfreefare; card-OS-specific values marked
