I don't know if you're talking about the 3-D Secure / Verified by Visa system, but the major flaw of this technology is that the merchant is the only one responsible for putting it up or not.

I used to work in e-commerce and my company simply disabled the SMS protection because it would harm sales and the platform would sometimes completely crash.

On the other hand there is no way (that I know of) that I, as a customer, could prevent my card being used in non secured websites. So this system makes legitimate purchases harder and doesn't prevent fraud.

We need a different technology than credit card for online payments, they are not secured enough and any layer of security that we add around them won't work.
