I'm a European expat living in Asia. I usually hide my credit card at my apartment. However, I'm a bit scared about losing it when I carry it (wallet robbed or lost).
That's why I already scrubbed the CVV (security code) at the back of the card thinking that nobody could use it on Internet.
However, the thread What's the impact of disclosing the front-face of a credit or debit card? made me realize the CVV (security code) was not required on some websites (such as Amazon.com) when buying stuff.
So I'm wondering whether it would be a good idea to cut some digits of the card PAN (16-digit number which I know by heart) with a Stanley knife?
The only problem I can see is that a shop assistant could refuse me to pay with a "damaged" card. Nevertheless, I only use my credit card to get some cash, I suppose ATMs don't care about a "damaged" card (I guess they only get data from the chip).
Thanks for your help.
Update (21 hours later): Thanks all for your meaningful thoughts.
All of you (for the moment I got 4 answers: from Eric, Rory, Bruce and Lucas) think I shouldn't bother removing some digits from my card.
Some of you wrote I shouldn't worry because my bank would pay me back if somebody fraudulently use my card. True.
However, as this problem never happened to me, I don't know whether it's easy to be paid back: I guess my bank would ask for some good explanations about the theft and so on.
I forgot to mention in my question that my bank is Irish and my personal address for my card is my parents' address in France (as I travelled a lot). If somebody steals my card and buys an expensive camera on Amazon and get delivered in the city where I live in Asia, how could the bank believe it was not me?
That's why I thought it would help to remove some digits. I realize I was too naive and Eric's message made me understand that some thieves would be able to get the card number from its chip whatever I would do to the card.
In conclusion, I understand that cutting my card would only prevent "bad/inefficient" thieves (quite funny to write that) from using it.
As you advised I keep (for a long time) my bank "emergency phone number" at my fingertips in case of theft.
Thanks again for all your thoughts and advice.
