Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0xE9 | Y(1): b1110, K: 9 (historical bytes) |
| TB(1) = 0x00 | VPP is not electrically connected |
| TC(1) = 0xFF | Extra guard time: 255 (special value) |
| TD(1) = 0x81 | Y(i+1) = b1000, Protocol T=1 |
| ---- | |
| TD(2) = 0x31 | Y(i+1) = b0011, Protocol T=1 |
| ---- | |
| TA(3) = 0xFE | IFSC: 254 |
| TB(3) = 0x45 | Block Waiting Integer: 4 - Character Waiting Integer: 5 |
| ---- | |
| Historical bytes | 43 4C 61 69 72 65 33 20 36 |
| Category indicator byte: 0x43 | (proprietary format) "Laire3 6" |
| TCK = 0x28 | 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.
