Is it better to bring cash from home and exchange it?

No. You will lose value twice: once when you buy the foreign currency at home, and again if you have to trade it back.

Should I use a credit card or debit card?

Use a credit card for all purchases to earn points and benefit from fraud protection. Use your debit card only to withdraw cash at ATMs.

What if the ATM eats my card?

Go inside the bank branch immediately if it is open. If it is closed, call the number on the back of your card (or your bank's international line) to cancel the card and report the location.

Choosing Between Currency Exchange and ATMs Abroad

Always use an ATM for local currency to get the best exchange rate, as currency exchange booths typically charge hidden fees and offer poor rates. Use a bank-affiliated ATM connected to a major network like Visa or Mastercard to minimize transaction costs.

Check your bank's international fees. Call your bank or check your account terms online. You are looking for 'foreign transaction fees' and 'out-of-network ATM fees.' If your card charges more than 1% per transaction, open a travel-friendly checking account (like Charles Schwab or Revolut) before you leave.
Identify partner banks. Many global banks have partnerships. Check if your home bank has a partner in your destination country; using their ATMs will often waive withdrawal fees.
Locate an official bank ATM. Only use ATMs physically attached to a reputable bank branch. Avoid standalone ATMs in tourist shops or convenience stores, as these often charge exorbitant 'convenience' fees.
Decline the 'dynamic currency conversion'. When the ATM asks if you want to be charged in your home currency or the local currency, always choose the local currency. Choosing your home currency allows the ATM owner to set a proprietary, unfavorable exchange rate.
Avoid currency exchange booths. If you absolutely must use an exchange booth at an airport, only exchange the bare minimum (e.g., $50) for immediate needs like transit, and get the rest of your cash from a bank ATM.
