@miriam98 - Frankly, I’ve never understood the CCV credit card number serving as some so-called means of protection. You’re just adding an additional number to the number that already exists – there doesn’t seem to be any added protection.
This reminds me of people who steal software and engage in piracy. Most software will ask for a serial key to ensure that you’re authorized to use it.
However, people who distribute pirated software will not only give you the software, but they also give you the key. What kind of a deterrent is a serial key against people who are fundamentally dishonest?
The criminals who are committing identity theft with credit cards are hawking credit card information, with numbers, CCV and all, on Internet forums.
I agree that the best defense is just to stay alert. Maybe one day we’ll all go to biometric scanners and that will be the real game changer.
