Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
| TS = 0x3B | Direct Convention |
|---|---|
| T0 = 0x6F | Y(1): b0110, K: 15 (historical bytes) |
| TB(1) = 0x00 | VPP is not electrically connected |
| TC(1) = 0xFF | Extra guard time: 255 (special value) |
| ---- | |
| Historical bytes | 00 56 72 75 54 6F 6B 6E 73 30 20 00 00 90 00 |
| Category indicator byte: 0x00 | (compact TLV data object) Tag: 5, Len: 6 (card issuer's data) Card issuer data: 72 75 54 6F 6B 6E "ruTokn" Tag: 7, Len: 3 (card capabilities) Selection methods: 48 - DF selection by file identifier - DF selection by path Data coding byte: 32 - Behaviour of write functions: proprietary - Value 'FF' for the first byte of BER-TLV tag fields: invalid - Data unit in quartets: 0 Command chaining, length fields and logical channels: 0 - Logical channel number assignment: No logical channel - Maximum number of logical channels: 1 Mandatory status indicator (3 last bytes) LCS (life card cycle): 0 (No information given) SW: 90 00 |
