| # | Byte | Name | Description |
|---|---|---|---|
| 0 | 3B | TS | Direct convention (TS = 3B) |
| 1 | 80 | T0 | Format byte: 0 historical bytes, Y1=0b1000 (TA1=absent, TB1=absent, TC1=absent, TD1=present) |
| 2 | ?? | TD1 | TD1: T=0 protocol indicator, Y2=0b0000 (TA2=absent, TB2=absent, TC2=absent, TD2=absent) masked |
1 byte is 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.
