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 problem is to get the right information. It’s not as simple as their name and their account number. All the information in there is encrypted so someone could make the chip and still get nothing out of it because they cant get the actual data without the right encryption key
