> there is one entity that is reasonably well funded, has incredibly strong capabilities for card fraud detection, and is well motivated to identify the fraud: the credit card companies. IME, credit card fraud detection is a user experience nightmare. There are dozens of false positives per true positive, and the confirmation system is implemented with little regard for the user: I'm not given a reason my purchase is denied, so I have no idea what's going on or a tip on how solve it (I know the security reasons for it, but that's the credit card company's problem, not mine - find a better way); the confirmation request is delayed, so that I've already had to move on to other solutions (call the vendor, try another order, vendor, or credit card); and the confirmation is not integrated with the purchase - the purchase is denied, it isn't put on hold so I can respond to the confirmation, and I have to start all over. I know I'm not supposed to use all caps on HN, but I HATE the purchase experience. It wastes a lot of time, sometimes an hour or more, and is incredibly frustrating. I'm doing nothing wrong; I don't like the credit card company using my time like it's worthless nor do I enjoy being treated like a criminal for making a simple purchase. I purchase less online because of the experience.
