Ask Slashdot: How Do You Keep Your Credit Card Secure?
It's easy to pontificate about the best security practices -- but the real test is what we do with our own money. Long-time Slashdot reader Keybounce writes:
So, like most of you, I recently got a new credit card with a chip in it. I was not worried about that -- I know the chips are harder to copy and counterfeit. But I recently discovered that the card is also a radio card -- swiping it near the screen caused an message to show up on the reader. In this case, it told me to use the chip reader instead, but this means it has an active radio signal, and could be "hacked" -- stolen by someone with the right device.
How can I prevent this? Is there anything I can do that will disable the radio signal and still leave the chip functioning?
At least 200 million RFID credit cards were in circulation by 2012, even though their signals could be easily intercepted, prompting the introduction of RFID-blocking wallets and sleeves. But what's the alternative? A recent article in Quartz argued that America's transition to chip cards has been an utter disaster (since the banks dispensed with PIN numbers altogether and now validate with only an electronic signature). Is the answer to just use a mobile wallet like Apple Pay or Android Pay -- or to always pay with cash?
So leave your own answer in the the comments. How are you keeping your own credit card secure?

I am not liable for fraudulent charges.
Sometimes you are. I was fraudulently charged $19/month for several months by Travelocity. I disputed the charges through Bank of America, and BOA told me that Travelocity was their "marketing partner" so the fraudulent transactions could not be reversed. I cancelled the credit card, closed all my BOA accounts, and switched to Wells Fargo (the only other bank within bicycle distance of my house). I also never again used Travelocity for anything. I periodically go into the local BOA branch and steal their ink pens.
Don't they kick you out when the transaction is denied?
If you are paying $2000 in Mexico, you are going to the wrong strip clubs. Try walking more than 1 block from the border.
Just make sure to remember to put your plane ticket to Mexico on another card!
Why is there an "insightful" mod and why isn't it "-1"? If I wanted insight, I wouldn't be reading
I am already using Vaultcard but since I carry the cards close to my genitals, I decided to add a layer of protective gearing constituted of a lead casing. It ended up requiring an additional belt that I wear under my clothes so it is not apparent. It is a little heavy and uncomfortable but in the end I feel safe in all regards and proud to be using the latest technologies.
Everything I write is lies, read between the lines.
I recently found out that my card was leaking radio waves in the visible spectrum! This is really nefarious because the radio waves do not actually originate from the card itself. When a store, hacker, or other third party sends radio waves in the visible spectrum towards my credit card, the card returns the signal back to a wide range of locations with the user's name, the credit card number, and even the cvv code on the back!
The worst part is that there are even visible spectrum enhancers on the market, which turn the radio signal, which is usually only decipherable at 2-3 ft, into a signal that can be deciphered from 30-100 ft. I can't even believe that these things are legal, or that the card returns these radio waves in the visible spectrum!
The world is going to hell in a handbag!
You're overreacting. The technology to block that portion of the spectrum has been integrated into wallets for centuries. It's quite neat tech - google for leather.
