ETX
Where:
<STX> = 02h, <ETX> = 03h
Card Type is 8x for an enhanced encryption format and 0x for original encryption format.
Value
00h / 80h
01h / 81h
03h / 83h
04h / 84h
For Type 04 or 84 Raw data format, all the tracks are encrypted and no mask data is sent. There
are no track indicators of '01', '02', or '03' in front of each track.
Track indicators '01','02', and '03' still exist for non-encrypted mode.
Field 4:
Bit 0: 1—track 1 decoded data present
Bit 1: 1—track 2 decoded data present
Bit 2: 1—track 3 decoded data present
Bit 3: 1—track 1 decoded data present
1—track 2 decoded data present
Bit 4:
Bit 5: 1—track 3 decoded data present
7—Reserved for future use
Bit 6,
Note 2: Track 1 3 status byte.
Decoded bit: 1 for decode success or no sampling data; 0 for decode error (with sampled data but
failed to decode)
