Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0xF8 | Y(1): b1111, K: 8 (historical bytes) |
| TA(1) = 0x13 | Fi=372, Di=4, 93 cycles/ETU (43010 bits/s at 4.00 MHz, 53763 bits/s for fMax=5 MHz) |
| TB(1) = 0x00 | VPP is not electrically connected |
| TC(1) = 0x00 | Extra guard time: 0 |
| 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 | 4A 43 4F 50 76 32 34 31 |
| Category indicator byte: 0x4A | (proprietary format) "COPv241" |
| TCK = 0xB7 | 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.
