You’ll want to make sure your credit card comes with a chip, which is standard technology, especially in Europe. Not only are they increasingly common, but EMV chips provide more security against fraud than swiping the magnetic strip on the back of your card. You’ll know if your card has an EMV chip if you can insert it into a card reader when you make a purchase, rather than swiping. Some merchants may even deny your credit card if it does not have a chip.
