Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0x89 | Y(1): b1000, K: 9 (historical bytes) |
| TD(1) = 0x80 | Y(i+1) = b1000, Protocol T=0 |
| ---- | |
| TD(2) = 0x01 | Y(i+1) = b0000, Protocol T=1 |
| ---- | |
| Historical bytes | 66 49 46 58 42 53 32 47 6F |
| Category indicator byte: 0x66 | (proprietary format) "IFXBS2Go" |
| TCK = 0x32 | correct checksum |

The parsing code is part of pyscard and is available at parseATR.py.
The list of known ATR is also available online at smartcard_list.txt.
My blog contains a serie of artickes about ATR bytes.
