Decode flag will set to 1 (B3, B4 and B5 all set to 1) in OPOS raw data mode.
Track ID
Track ID is a byte of ID, it will be '1', '2' and '3' for track 1, 2 and 3; it is not
accurate to use start sentinel to identify track.
Track x Error
Track x error is a byte of flags, it will be in format of: 0 0 1 b4, b3, b2 b1 b0
b0 1: Start sentinel error (0: Not start sentinel error).
b1 1: End sentinel error (0: Not end sentinel error).
b2 1: Parity error (0: Not parity error).
b3 1: LRC error (0: Not LRC error).
b4 1: Other error (0: Not other error).
Track x Error is set to 0x20 in OPOS raw data mode.
Track Length
Assume actual "Track x Data Length" is hex code xy; the Track x data length for
OPOS mode output will be hex code 3x, 3y.
Track x data length does not include the byte of "Track x data LRC", it is <30>
<30> in case of read error on track x.
Track Data
“Card Track x LRC code” is track x card data.
