Credit vs Debit vs Prepaid Card Abroad: What to Use

A credit card borrows up to an agreed limit. Purchases can have an interest-free grace period if you repay the full balance on time; a minimum payment does not avoid interest. A debit card spends money in your account, and with an overdraft it can still put you into debt; in the US you choose whether to opt in to overdraft coverage for ATM and everyday debit card transactions (CFPB). A prepaid card spends a balance you load first, but auto top-up, a linked funding card and, in some US programs, overdraft features can take you past that amount (CFPB).

Protection depends on who holds the money. In the UK, e-money institutions and authorised payment institutions must safeguard customer funds, which is different from FSCS cover for bank deposits, and small payment institutions do not have to safeguard (FCA). In the US, money on some prepaid cards has pass-through FDIC insurance when the program meets the conditions, including registering the card in your name (CFPB). That covers the failure of the bank, not every loss.

At check-in or car pick-up, the hotel or rental company often places a hold on your card. It is an authorization, not a final charge, but it lowers what you can spend until it is released. On a credit card it uses part of your limit. On a debit or prepaid card it locks your own money, which you may need for the rest of the trip.

Example (credit card): a EUR 1,500 limit, EUR 300 already spent and a EUR 500 hotel hold leave EUR 700. A second EUR 400 hold for a rental car on the same card leaves EUR 300.

Example (debit card): EUR 1,000 in the account and a EUR 500 hold leave EUR 500. If EUR 350 of that is for a bill at home, only EUR 150 is left for the trip until the hold is released.

Before you book, read the payment section or ask the property or rental branch which card types it accepts for the deposit, whose name must be on the card, whether you need the physical card and how much it will hold. Avis, for example, publishes a separate debit card policy for its US rentals. If the booking asks for a credit card, bring one in the guest’s or main driver’s name.

Use a debit or multi-currency card for ATM cash and stay inside its free allowance. Wise is free up to USD 250 a month, then USD 1.95 + 1.95% per withdrawal (US pricing, as of 21 Sep 2026). Revolut Standard gives 5 withdrawals or GBP 200 a rolling month, then 2% with a GBP 1 minimum (UK, as of 26 Sep 2026). N26 charges 1.7% on non-euro cash on Standard and Smart (EU plans, as of 26 Sep 2026). The ATM owner may add its own fee.

Example: a EUR 200 withdrawal. Say your debit card charges EUR 3 and the ATM operator adds EUR 4: EUR 7 in total. A credit card with a EUR 6 cash advance fee plus the same EUR 4 costs EUR 10 before interest. At 24% a year, 30 days of interest on EUR 200 add 200 × 0.24 × 30 / 365 ≈ EUR 3.95, so about EUR 13.95 in total.

If the ATM offers to convert the withdrawal into your home currency, choose the local currency.

A prepaid euro card is a card you load with euros before the trip and spend down. Most travelers now get the same result from a multi-currency account card: top up Wise or Revolut, hold a euro balance, pay from it and keep what is left for the next trip. Crypto-funded cards such as Bybit Card EU and the Crypto.com prepaid Visa work the same way, but they spend money you keep on the exchange.

Wise and Revolut suit most travelers who want a euro balance with no monthly fee. Wirex has a free Standard plan. Bybit Card EU suits people who already hold crypto with Bybit EU. N26 is a different product: a euro bank account with a Mastercard for residents of its supported European countries, with no N26 fee on card payments in any currency.

Plan for leftover money before the trip ends. Keep the account open until refunds and released deposits arrive, because a refund goes back to the card you paid with. Converting a balance back costs another conversion, and an idle card can attract an inactivity fee: Crypto.com’s US terms effective 1 Sep 2026 list USD 5.95 a month after 12 months without activity. Top-ups can cost money too: Crypto.com’s US examples are 1% from a debit card and 2.99% from a credit card (as of 26 Sep 2026).

If a card is lost or you see a payment you did not make, freeze the card in the app and report it through the issuer’s official channel straight away, without waiting for a merchant’s promised refund.

For a problem with a merchant you did use, keep the booking terms, receipt and dated messages, and check the issuer’s dispute deadline early. Under US billing-error rules, the disputed amount is handled separately but the rest of the statement stays payable (CFPB), so pay the undisputed part on time. After the trip, match charges and refunds against your receipts and check that every hold was released.
