Your call.
That said, the purpose of CVV is to stop *one* type of fraud - it's to stop a=
skimmer from being able to do mail-order/internet-order with your card numb=
er. The CVV is not on the magnetic strip, so a skimmer installed at the ATM=
or gas pump won't be able to capture it.
There's a similar value on the magnetic strip that keeps the internet site y=
ou gave your card number and CVV to from being able to print cards and use t=
hem at the gas pump.
Certainly they don't stop all fraud. They stop one type of fraud.=
