Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0xFF | Y(1): b1111, K: 15 (historical bytes) |
| TA(1) = 0x97 | Fi=512, Di=64, 8 cycles/ETU (500000 bits/s at 4.00 MHz, 625000 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) = 0x43 | Block Waiting Integer: 4 - Character Waiting Integer: 3 |
| ---- | |
| Historical bytes | 80 31 80 65 B0 84 61 60 FB 12 0F FD 82 90 00 |
| Category indicator byte: 0x80 | (compact TLV data object) Tag: 3, Len: 1 (card service data byte) Card service data byte: 128 - Application selection: by full DF name - EF.DIR and EF.ATR access services: by GET RECORD(s) command - Card with MF Tag: 6, Len: 5 (pre-issuing data) Data: B0 84 61 60 FB "..a`." Tag: 1, Len: 2 (country code, ISO 3166-1) Country code: 0F FD Tag: 8, Len: 2 (status indicator) SW: 90 00 |
| TCK = 0x0D | correct checksum |
