bravo is the exact type of stupidity you would see around
listen that type of advise and you would go far away
every track can be edited and deleted 1 by 1
maybe change the software is not the right one or the version

When will I need track 1 then?

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

Which country is youre fuel card from ?
