That's different to the PIN. CVV is for cardholder not present transactions, PIN is for one's where you're there.

Also CVV needs the 16 digit card number, card holder name and expiry as well..

I'd almost guarantee that trying to brute-force a CVV number will get your card blocked real fast.

I got an email from my credit card after a single CVV failure, because the guy at the Apple store entered it wrong.
