Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:

|---|---|
| T0 = 0x68 | Y(1): b0110, K: 8 (historical bytes) |
| TB(1) = 0x00 | VPP is not electrically connected |
| TC(1) = 0x00 | Extra guard time: 0 |
| ---- | |
| Historical bytes | 4D 43 43 43 4C 32 2E 31 |
| Category indicator byte: 0x4D | (proprietary format) "CCCL2.1" |

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.
