Enter an ATR (Answer To Reset) and I will parse it for you.
Parsing ATR:
TS = 0x3B | Direct Convention |
---|---|
T0 = 0xD5 | Y(1): b1101, K: 5 (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) = 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) = 0x3A | IFSC: 58 |
TB(3) = 0x7D | Block Waiting Integer: 7 - Character Waiting Integer: 13 |
---- | |
Historical bytes | 80 73 C8 21 10 |
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: 16 - Logical channel number assignment: by the card - Maximum number of logical channels: 1 |
TCK = 0x30 | correct checksum |
Possibly identified card:
