mastercard and visa oblige you to secure yourself

Both firms will oblige firms processing and using their credit cards to secure their networks, infrastructure and procedures. Maybe some will now be waking up. They are left no choice. Tell their customers they can't take visa cards to buy their stuff because Visa refuses to work with them because their network is insecure ? No customer would spend even a dime with them.
