The best way to pay abroad isn't one card. It's a system: a main method, a backup on a different rail, and a little cash — so that no single failure ruins your day.
The three-layer setup
- Primary: a card with no (or low) foreign transaction fees, added to your phone wallet.
- Backup: a second card on the other network (Visa ↔ Mastercard), from a different bank, stored separately.
- Cash: a small amount of local currency for the airport transfer, tips and places that don't take cards.
Comparing your options
| Method | Best for | Watch out for |
|---|---|---|
| Low-fee debit/credit card★ Uncle's pick | Everyday spending | International use may need enabling; limits |
| Phone wallet (tap to pay) | Speed and security in card-friendly places | Needs a charged phone; card's fees still apply |
| Multi-currency account/card | Holding and converting several currencies | Availability depends on your country of residence |
| Prepaid travel card | Budget control, separating travel money | Loading fees, rate markups, expiry rules |
| Cash | Markets, tips, rural areas, transport | Loss/theft; poor exchange rates at airports |
Fees and availability differ by provider and country — check the current terms of any product you use.
What each option really costs
- No-fee card, paying in local currency: close to the Visa or Mastercard network rate. Check it with the Visa (opens in a new tab) or Mastercard (opens in a new tab) calculators.
- Card with a foreign transaction fee: the network rate plus your bank's percentage, often 2–3% per purchase.
- Accepting "pay in your home currency" (DCC): the merchant provider's rate and markup. In the EU, the markup must be shown as a percentage before you pay.
- Airport cash counter: commonly around 14% above reference rates, according to NerdWallet's September 2026 figures.
A note for travellers from Africa
Many travellers from African countries face extra friction that most travel-money guides ignore:
- International transactions disabled by default on some local cards.
- Caps on foreign spending or withdrawals on local-currency cards in some markets.
- Fintech availability varies: a multi-currency product popular in Europe may not accept residents of your country.
Security basics
- Use ATMs inside banks or busy areas.
- Turn on transaction notifications.
- Know how to freeze each card from its app.
- Keep the backup card in a different bag from your main wallet.
- Save your bank's international helpline number offline.
- Choose credit over debit for hotel and car-hire deposits where you can. Holds on a debit card lock up your own money until they're released.
Uncle's verdict
Main card in your phone, backup on a different network in your bag, a little cash in your pocket — and local currency, every time. Next: Visa vs Mastercard abroad.
