⚠ TCK check failed — ATR may be corrupted or masked
2 bytes are shown as ?? because the ATRMask at those positions is 00 —
these bits are variable across card instances and were not recorded. The analysis above is based on the known bytes only.
Use smartcard-atr.apdu.fr with your card's real ATR for a complete decode.
