Would they go out of business? They make a % of every transaction too. What % of a credit card companies income is transaction fees vs account interest? I would argue that a credit card company could probably operate on transaction fees alone. Sure they might need to downsize, but I think the transaction fee would be enough to pay for the minimum infrastructure to run such a company providing the service they provide.
