Years ago, I had my credit card stolen. Not from my wallet, but from across the room at a conference.
Thrives can steal your credit card info if your card does not have a chip on it. Called EMV or chip and PIN technology, US retailers and some banks are slow to convert. If your debit card does not have a chip, call today and tell them you want a replacement with a chip on it. Retailers that don’t have EMV machines are liable if something goes wrong.
I stopped carrying that magnetic stripe only card and now only carry chipped cards where possible. In the case of my Costco membership card, with only a magnetic stripe, I protect it with tin foil.
You can cover a thin piece of cardboard or 2 with tin foil. Make sure it is near the magnetic strip side.
Always check your charges for odd things.
In my case, the theif bought about $100 worth of baby things from Best Buy (handheld carpet shampooer) and Babies R Us. I even had the shipping address and reported it to my card institution.
If too much time had lapsed before I caught the problem, I would have called Zander, my ID insurance protector service.
Aluminum foil to foil those cyber thrives!
