Masked Area
The data format of each masked track is ASCII.
The clear data include start and end sentinels, separators, first N, last M digits of the
PAN, card holder name (for Track1).
The rest of the characters should be masked using mask character.
Set PrePANClrData (N), PostPANClrData (M), MaskChar (Mask Character)
N and M are configurable and default to 4 first and 4 last digits. They follow the
current PCI constraints requirements (N 6, M 4 maximum).
Mask character default value is ‘*’.
