From the view on security of the card.
The CVV pin behind the card is visible to anyone who hold the card, e.g. the waiter, cashier, etc.

Let's think about a scenario here.
You went to a fancy restaurant, waiter take your card to the cashier, paid the less than RM250 bill using contactless feature.
Couple of months later, suddenly your card was charged with several thousands on foreign website, which requires only name, card number and cvv. No TAC/OTP sms required.
You have no idea where your card info was stolen as you use the card in many places in past 2 months.

The CVV could be the weak link here.
Is there any T&C that says you cannot scrape off the CVV?
Or has anyone done it?

My friend thought so too.
Until one day, the iTunes transactions suddenly pops up. Around RM2K.
Fortunately the bank is willing to waive all charges and interest.
However, it took a couple of months and many phone calls/emails.

It's like when you saw someone in car accident, and you will think, "That won't happen to me".
Until one day...

Just use alexwsk recommendation as a precaution.
