Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0xDC | Y(1): b1101, K: 12 (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) |
| TC(1) = 0xFF | Extra guard time: 255 (special value) |
| TD(1) = 0x81 | Y(i+1) = b1000, Protocol T=1 |
| ---- | |
| TD(2) = 0x91 | Y(i+1) = b1001, Protocol T=1 |
| ---- | |
| TA(3) = 0xFE | IFSC: 254 |
| TD(3) = 0x1F | Y(i+1) = b0001, Protocol T=15 |
| ---- | |
| TA(4) = 0xC3 | Clock stop: no preference - Class accepted by the card: (3G) A 5V B 3V |
| ---- | |
| Historical bytes | 80 73 C8 21 13 66 05 03 63 51 00 02 |
| Category indicator byte: 0x80 | (compact TLV data object) Tag: 7, Len: 3 (card capabilities) Selection methods: 200 - Implicit DF selection - DF selection by partial DF name - DF selection by full DF name Data coding byte: 33 - Behaviour of write functions: proprietary - Value 'FF' for the first byte of BER-TLV tag fields: invalid - Data unit in quartets: 1 Command chaining, length fields and logical channels: 19 - Logical channel number assignment: by the card - Maximum number of logical channels: 4 Tag: 6, Len: 6 (pre-issuing data) Data: 05 03 63 51 00 02 "..cQ.." |
| TCK = 0x50 | correct checksum |
Possibly identified card:
