Swiping Fuel Cards - Help

[Zaeer]

in credit or debit card is a track 1 but not on gas card
even without track 1 credit or debit card can work with only track 2
but if you ask for your gas card with originally only track 2
that mean is no need for track 1
so if software block try to change software because you can read or write or delete any track, 1 by 1, without forcing you to enter track 1
