Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0x7B | Y(1): b0111, K: 11 (historical bytes) |
| TA(1) = 0x18 | Fi=372, Di=12, 31 cycles/ETU (129032 bits/s at 4.00 MHz, 161290 bits/s for fMax=5 MHz) |
| TB(1) = 0x00 | VPP is not electrically connected |
| TC(1) = 0x00 | Extra guard time: 0 |
| ---- | |
| Historical bytes | 00 31 C0 64 77 E9 10 00 01 90 00 |
| Category indicator byte: 0x00 | (compact TLV data object) Tag: 3, Len: 1 (card service data byte) Card service data byte: 192 - Application selection: by full DF name - Application selection: by partial DF name - EF.DIR and EF.ATR access services: by GET RECORD(s) command - Card with MF Tag: 6, Len: 4 (pre-issuing data) Data: 77 E9 10 00 "w..." Mandatory status indicator (3 last bytes) LCS (life card cycle): 1 (Creation state) SW: 90 00 |
Possibly identified card:
3B 7B 18 00 00 00 31 C0 64 77 E9 10 00 01 90 00

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.
