Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0x9C | Y(1): b1001, K: 12 (historical bytes) |
| TA(1) = 0x95 | Fi=512, Di=16, 32 cycles/ETU (125000 bits/s at 4.00 MHz, 156250 bits/s for fMax=5 MHz) |
| TD(1) = 0x80 | Y(i+1) = b1000, Protocol T=0 |
| ---- | |
| TD(2) = 0x81 | Y(i+1) = b1000, Protocol T=1 |
| ---- | |
| TD(3) = 0x1F | Y(i+1) = b0001, Protocol T=15 |
| ---- | |
| TA(4) = 0x03 | Clock stop: not supported - Class accepted by the card: (3G) A 5V B 3V |
| ---- | |
| Historical bytes | 90 67 46 4A 01 00 54 04 F2 72 FE 00 |
| Category indicator byte: 0x90 | (proprietary format) "gFJ..T..r.." |
| TCK = 0xC0 | 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.
