What would be the best way to cover the 3 digit code at the back of a credit card? Some suggest using correcting liquid (but it is easy to remove it and apply new one).

Many restaurants still get our cards to swipe at their counter. Only very few go to table to swipe it. Also sometimes we gave our credit card to gasoline station personnel whenever we have our gas filled up.

What do you use to cover the 3 digits? What is the most sensitive warranty fragile sticker around?

The logic is that when we found out it was tampered, then we would block the card immediately (before they can use it though).

If you are concerned about this you should contact your credit card provider for advice.

They just say to tape it, and can't provide other methods. That is why I was asking what kinds of cover you guys used.

3/8" drill bit.

Memorize it and scrape it off with a knife, if you're worried about it.

I don't really care that much, because I know that the banks are the ones that lose money if my card is used fraudulently, provided I notice in a month or so and tell them.

Also why I don't EVER use my ATM cards.

Since there is really no practical means to cover the code while preventing a bad actor from uncovering it and since there is little need to do this in light of how credit card companies handle fraud, I hereby close this thread and thank you for contributing here.

To the OP I believe you are worrying about nothing here. The code is used to verify that the mag strip and card number are the same As a common malpractice was to change the mag strip with a different card number. it has since expanded to online use and other places as a means to verify that you have a valid card.

I doubt any retailer seeing that scraped off would allow you to provide them with that number.

Thanks everyone.
