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) = 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) = 0x11 | Y(i+1) = b0001, Protocol T=1 |
| ---- | |
| TA(3) = 0xFE | IFSC: 254 |
| ---- | |
| Historical bytes | 80 31 C8 54 43 56 35 07 73 FF A1 C0 |
| Category indicator byte: 0x80 | (compact TLV data object) Tag: 3, Len: 1 (card service data byte) Card service data byte: 200 - Application selection: by full DF name - Application selection: by partial DF name - EF.DIR and EF.ATR access services: by READ BINARY command - Card with MF Tag: 5, Len: 4 (card issuer's data) Card issuer data: 43 56 35 07 "CV5." Tag: 7, Len: 3 (card capabilities) Selection methods: 255 - Record identifier supported - Record number supported - Short EF identifier supported - Implicit DF selection - DF selection by file identifier - DF selection by path - DF selection by partial DF name - DF selection by full DF name Data coding byte: 161 - EF of TLV structure supported - 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: 192 - Command chaining - Extended Lc and Le fields - Logical channel number assignment: No logical channel - Maximum number of logical channels: 1 |
| TCK = 0x3C | correct checksum |
