Why travel money deserves its own checklist
Most travellers spend hours researching flights and hotels, and a few minutes thinking about how they will actually pay for things when they land. This is a mistake.
Foreign transaction charges, unfavourable exchange rates, and dynamic currency conversion quietly erode travel budgets. Very little of it is necessary.
Here is what to sort before you fly.
1. Notify your bank, or switch to a travel-friendly account
If you use a standard high-street bank account as your primary travel card, notify them before you depart. Unexpected international transactions can trigger fraud blocks, leaving you without access to funds at the worst possible moment.
Better still, open a multi-currency travel account before your trip. Wise converts at the real mid-market exchange rate, the one shown on Google, and lets you hold balances in dozens of currencies. The Wise debit card works at most ATMs and card terminals worldwide. Our what is Wise explainer covers how the account works, and how to use Wise abroad is a practical setup walkthrough.
2. Set up your multi-currency account before you leave
If you are using a travel account, do the setup at home rather than at the airport or on the day of departure. Verification can take a day or two on first sign-up.
Once your account is open:
- Add funds in your home currency
- Convert to the destination currency before you fly, when rates are stable
- For multi-country trips, hold balances in each currency you will need
3. Understand ATM strategy by region
In most of Europe, Southeast Asia, Japan, and the Americas: card payments are widely accepted and you will rarely need much cash.
In parts of Africa, the Middle East, and rural Asia: cash is far more important. Withdraw enough to cover a day or two at a time from ATMs in airport arrivals halls or city banks, and avoid airport exchange counters, which consistently offer poor rates.
General rule: withdraw in the local currency from an ATM rather than exchanging at a bureau de change. Check your own account's ATM allowance and charging structure before you travel, since these vary by provider and change from time to time.
4. Always pay in local currency
If a card terminal abroad asks whether you want to pay in your home currency rather than the local currency, always say no. This is called dynamic currency conversion, and it lets the merchant apply their own exchange rate, which is reliably worse than your bank's.
Always choose the local currency. Every time.
5. Emergency backup
Keep a small amount of cash somewhere separate from your main wallet. US dollars and euros are the most widely accepted emergency currencies. A card from a second account or bank is also worth having, because if your primary card is lost or blocked your trip should not grind to a halt.
6. Inform someone at home
Leave your itinerary, including countries visited and approximate dates, with a trusted contact at home. If your card is blocked for suspected fraud, having someone who can call the bank on your behalf can be the difference between a minor inconvenience and a major problem.
7. Sort money and entry admin together
Money and entry requirements tend to be handled separately and then collide at the border, where proof of funds is a routine question for visa-free arrivals. Doing both in one sitting saves rework.
- Check what your corridor actually requires with Yoogo's corridor checker.
- Confirm your passport has enough remaining validity. See passport validity rules.
- If you are crossing several borders, our multi-country visa planning guide covers checking each leg.
- Sort connectivity at the same time, since a blocked card is much easier to resolve with working mobile data. See our connectivity checklist.
Quick pre-departure checklist
- Primary travel account set up and funded
- Destination currency converted or queued
- Bank notified if using a high-street card
- ATM allowance and charging structure understood for your account
- Small cash reserve in US dollars or euros packed separately
- Backup card packed in a different location to the primary
- Passport validity checked against your destination's rule
- Corridor requirements checked and any authorisation applied for
8. Know where to check a rate
Before you convert anything, and before you accept a card terminal's offer to charge you in your own currency, it helps to know roughly what a fair conversion looks like. Our currency converter gives you a reference point for any pair, and it is worth glancing at it before you leave and again once you land.
A few pairs travellers ask about most often:
The point is not to chase a number. It is to have a reference in your head so that dynamic currency conversion, covered above, is obvious when a terminal offers it. If you are using a multi-currency account, our guides to what Wise is and Wise compared with a high-street bank cover how the conversion is handled.
Frequently asked questions
Should I tell my bank I am travelling?
Yes, if you are relying on a standard high-street account. Unexpected foreign transactions are a common trigger for automated fraud blocks.
Is it better to use cash or card abroad?
Card in most of Europe, the Americas, Japan, and much of Southeast Asia. Cash matters much more in parts of Africa, the Middle East, and rural Asia. Carry a small reserve either way.
Should I exchange money before I travel?
Converting through a multi-currency account before departure is generally better than exchanging at an airport bureau de change, which tends to offer the worst rates you will see.
What is dynamic currency conversion?
It is when a foreign card terminal offers to charge you in your home currency instead of the local one. The merchant sets the rate, and it is reliably worse than your own provider's. Always decline and pay in local currency.
How much cash should I carry?
Enough for a day or two at a time in card-friendly regions, more where cash dominates. Keep an emergency reserve in US dollars or euros separate from your main wallet.
Do I need a second card?
It is strongly worth having. A lost, damaged, or blocked primary card is one of the most common ways a trip goes wrong, and a backup on a different account removes the risk.
Will I be asked to prove I have enough money at the border?
It happens, particularly on visa-free arrivals. Proof of funds sits alongside onward travel and accommodation as a standard question, so have something you can show.
Which currencies work best as an emergency reserve?
US dollars and euros are the most widely accepted and the easiest to exchange at short notice almost anywhere.
