Can someone explain to me how a really smart hacker hasn’t figured out a way to design a chip for a card like a prepaid visa that tells the machine reading it that it always has money on it? Sorry if this sounds silly but the chip cards have information on them can that information not be hacked or edited? Or can they not have a machine like the bank uses to program your card but program it to be unlimited?
Thanks.

The card just says my account is XXXX at Bank Y. Then then the bank is contact (in split seconds) to say how much money is left.
So if you want a card that never runs out, it isn’t the card that needs to be hacked, it is the bank. Either trick the the real bank Y to always say “enough money” or have a fake bank (Fake-Y) that always says “enough money” to the merchant.
