Is it ok to change the name on track 1 or will it mess up the dump

You can change it without messing up the track but it's best to find a site that generate track 1 for you rather than doing it manually it's safer that way unless you know how to do it manually

I already have the tracks its just that some stores want to see if your id Match the name on the screen

To my knowledge what's in Track 1 won't effect track 2, you could put anything in track 1 but to be on the safe side make sure you either generate it or change it correctly so it won't be any suspicion while carding in store

So track 1 can be anything??

the smart thing is to generate a new track with your name instead of the name from the dump but technically yes track 1 can be anything because it won't affect the track 2

You can even not put track one and just put a "B", but then they wont get a name on the recite
