Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0xDA | Y(1): b1101, K: 10 (historical bytes) |
| TA(1) = 0x96 | Fi=512, Di=32, 16 cycles/ETU (250000 bits/s at 4.00 MHz, 312500 bits/s for fMax=5 MHz) |
| TC(1) = 0xFF | Extra guard time: 255 (special value) |
| TD(1) = 0x81 | Y(i+1) = b1000, Protocol T=1 |
| ---- | |
| TD(2) = 0xB1 | Y(i+1) = b1011, Protocol T=1 |
| ---- | |
| TA(3) = 0xFE | IFSC: 254 |
| TB(3) = 0x45 | Block Waiting Integer: 4 - Character Waiting Integer: 5 |
| TD(3) = 0x1F | Y(i+1) = b0001, Protocol T=15 |
| ---- | |
| TA(4) = 0x07 | Clock stop: not supported - Class accepted by the card: (3G) A 5V B 3V C 1.8V |
| ---- | |
| Historical bytes | 80 58 49 43 41 20 56 32 2E 30 |
| Category indicator byte: 0x80 | (compact TLV data object) Tag: 5, Len: 8 (card issuer's data) Card issuer data: 49 43 41 20 56 32 2E 30 "ICA V2.0" |
| TCK = 0xE9 | correct checksum |
Possibly identified card:
3B DA 96 FF 81 B1 FE 45 1F 07 80 58 49 43 41 20 56 32 2E 30 E9
Starcos chip card from Giesecke & Devrient (PKI)
