#	Byte	Name	Description
0	3B	TS	Direct convention (TS = 3B)
1	D2	T0	Format byte: 2 historical bytes, Y1=0b1101 (TA1=present, TB1=absent, TC1=present, TD1=present)
2	??	TA1	TA1: Fi=372, Di=RFU masked
3	??	TC1	TC1: extra guard time = 0 etu masked
4	81	TD1	TD1: T=1 protocol indicator, Y2=0b1000 (TA2=absent, TB2=absent, TC2=absent, TD2=present)
5	31	TD2	TD2: T=1 protocol indicator, Y3=0b0011 (TA3=present, TB3=present, TC3=absent, TD3=absent)
6	FE	TA3	TA3: IFSC=254 (max information field size for card)
7	58	TB3	TB3: CWI=8 (CWT=267 etu), BWI=5 (BWT≈11,427,840 etu)
8	C9	T1	Historical byte 1
9	04	T2	Historical byte 2
10	??	TCK	Check byte: XOR(T0…TCK) = 09 → ✗ INVALID masked

⚠ TCK check failed — ATR may be corrupted or masked

3 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.
