Now you are just confusing consumer protection with having a secure online payment system, which credit cards are not and never will be. The entire "transaction approval" shtick is just a bandaid for passing a static password around in clear text, your credit card info.

Consumer protection deals with chargebacks after the payment was made and the products/services are not delivered to required standards. This gives enormous power to credit card companies against merchants and enables obscene rent extraction against consumers who don't require it, yet still pay 2-4% more on everything they buy, even with other payment methods.
