If his card got stolen 6 months ago, then why wasn't it canceled?

That's the CIN number. More and more people are using it. Problem is, the more people that require it, the more it becomes useless. Now everyone who steals the credit card number also steals the CIN because it's used together with the original credit card number (it's like having a 19 digit credit card number instead of 16, just as easy to steal). Yes, it's still a bit of a deterrent, but in my experience we would ask shady customers for their CIN and everytime it was fraud, we still had a their CIN. If he does not have the CIN at all, then you can say it's fraud because every card has one, but just because he gives you one, don't assume it's legit.
