Money and Cards Across Many Currencies
A long journey may pass through eight or ten currencies. Knowing what to carry, which card to use and how to avoid quiet fees keeps your money working as hard as you do.
The short version: carry two debit or prepaid cards from different networks, one credit card, and a modest reserve of cash in a major currency. Withdraw local cash from bank ATMs as you go, pay by card where cards are welcome, and never let a machine convert the currency for you. That simple kit handles almost every country we travel through.
Money on a multi-country journey is not about carrying a great deal of it — it is about resilience and avoiding leakage. A lost card, a rejected transaction or a blocked machine should be an inconvenience, not a crisis. Build a small, redundant system before you leave and you will rarely think about money again.
The card kit to leave home with
Carry at least two cards that can withdraw cash, ideally on different networks — one Visa, one Mastercard — so that a network outage or a single blocked card never leaves you stranded. Add one credit card for larger payments, hotels and emergencies, since credit cards offer stronger purchase protection than debit cards. Keep the cards in two separate places: never all in one wallet.
Travel-focused debit and prepaid cards are worth seeking out. The best charge little or nothing for foreign transactions and reimburse or avoid ATM fees, which over a long journey adds up to real money. Whatever you carry, note the card numbers and the bank's international phone line separately, so a lost card can be cancelled within minutes.
Cash, and how much of it
Cash still matters, and on parts of the world we travel through it matters a great deal. Markets in Marrakech, family-run guesthouses along the Silk Road, rural East Africa on The Great Rift, tips, small fares and the occasional border fee are cash transactions. Plan to use local currency for daily small spending and cards for larger, formal payments.
Carry a modest reserve of a widely accepted currency — US dollars are the most universally exchangeable, euros a close second — as a fallback for emergencies and for the handful of places that price in them. Keep reserve notes clean, unmarked and recent: many countries reject worn or older-series bills, and the United States dollar in particular is often refused if torn or marked.
Getting local currency without losing money
The best exchange rate in most countries comes from an ATM attached to a recognised bank, drawing local currency directly from your account. Use ATMs inside bank branches where possible — they are safer and less likely to have been tampered with — and withdraw larger amounts less often to reduce per-withdrawal fees. Avoid airport exchange counters and standalone currency kiosks, whose rates are consistently the worst you will see.
There is one trap to learn by name: dynamic currency conversion. When an ATM or card terminal offers to charge you in your home currency rather than the local one, it sounds helpful and is not — the exchange rate it uses is poor and a fee is buried inside it. Always choose to be charged in the local currency and let your own bank do the conversion.
Telling your bank, and keeping cards alive
Before departure, tell each card issuer the countries and dates of your journey, or set a travel notice in their app. A long itinerary that lights up a new country every few days is exactly the pattern fraud systems flag, and a card frozen for suspected fraud in the middle of the Pacific Arc is a genuine nuisance. A quick notice prevents it.
Check each card's expiry date against your return date — a card that lapses mid-journey cannot be replaced abroad. Confirm you know your PINs, since some countries require a PIN where you would sign at home, and that your cards are enabled for international and online use. Two minutes of admin before you leave removes the most common money problem on the road.
Staying secure, and the journey-by-journey picture
Keep cards and cash divided across your luggage and your person, use a money belt or a zipped inner pocket in busy places, and prefer ATMs in daylight and in bank lobbies. Mobile and contactless payments are widely accepted in Spain and the cities of Istanbul, less so in rural Central Asia or the Andes — so the right balance of cash and card shifts as a journey moves.
Our guides know, region by region, where cards are reliable and where cash is king, and they will tell you when an ATM is your last good one before a stretch of countryside. Treat their advice as part of your money plan: it is local, current, and saves travellers from the only real cash mistake — running short in the one place a machine cannot help.
Quick answers
Should I exchange money before I leave home?
Carry a small reserve of US dollars or euros for emergencies and for places that price in them, but do not exchange large sums in advance — home-country exchange rates are usually poor. The better approach is to withdraw local currency from bank ATMs as you arrive in each country, which gives a near-interbank rate. Keep any reserve notes clean and recent, as worn bills are often refused.
What is dynamic currency conversion and why avoid it?
Dynamic currency conversion is when an ATM or shop terminal offers to charge you in your home currency instead of the local one. It feels convenient but uses a poor exchange rate with a hidden margin, so you lose money every time. Always decline it and choose to pay or withdraw in the local currency, letting your own bank handle the conversion at a fairer rate.
How much cash should I carry on a long journey?
Enough local currency for a few days of small spending — markets, tips, fares, the occasional fee — topped up from bank ATMs as you go, plus a modest reserve of US dollars or euros for emergencies. You rarely need large amounts of cash at once; the goal is never to be caught short before a stretch of countryside. Our guides will tell you where the last reliable ATM is.
