In this example - B4000001245790^John/Carol^03101011123400567000000 is that the data of Track one and 4000001234567890=03101011123495679991 - is that the data from the second track. Letter B implies that it`s a mastercard. 400000 123454689 zero - could be a range of the cardboard. ^John/Carol ^ - is that the name of the cardboard owner so on. Track two is quite kind of like Track one, tho' it's thought-about to be the most one and if you own it, you'll be able to organize the knowledge from Track one.
