If you’re travelling abroad, you’ll want to be mindful of foreign transaction fees, which can be very high with a credit or debit card. There’s also the matter of cash to consider: If you need cash, a debit card will be able to withdraw it from an ATM. While some credit cards can do this, you’ll run into cash advance fees and higher interest rates. You should also consider personal security. If your debit card gets stolen, the thief will have a card directly tied to your bank account. If your credit card gets stolen, you have an additional layer of protection, because the thief cannot spend your money directly. Generally, a combination of debit and credit card use may be your best bet when travelling abroad.
