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 doesn’t have any information on it about how much money is available. It’s essentially just a key for the account that does have the money, and it’s not the only key you need to unlock that account and spend the money.
For a hacker to pull off this kind of trick, they need to be able to hack the bank, not the card.
