Stop Paying Hidden Currency Conversion Fees
The exact phrases to use when ATMs and terminals try to trap you
You're at an ATM in Bangkok, pulling out cash for dinner. A screen appears: "Convert to USD now at a guaranteed rate?" It sounds helpful. Safe, even. You tap yes—and just lost 4-7% of your money to a scam called Dynamic Currency Conversion (DCC).
DCC happens thousands of times a day at ATMs, card terminals, and currency exchange kiosks worldwide. It's not illegal. It's just expensive. And the worst part? You'll never see that money again.
This guide shows you exactly what's happening, where it happens most, and the specific words to say—in multiple languages—to keep your money in your pocket.
What Is Dynamic Currency Conversion (DCC)?
When you swipe your card abroad, two things can happen:
- The good way: The merchant's bank processes the charge in the local currency, then your bank converts it at the real, mid-market exchange rate (usually the best rate).
- The DCC way: The terminal operator converts your purchase into your home currency at their own rate, pocketing the markup.
ATM operators and payment terminals offer DCC because they profit from the conversion spread. They make $2-3 per transaction, and with millions of travelers using ATMs daily, the math is obvious.
Here's the difference in real numbers: A 1,000 THB withdrawal in Thailand at mid-market rate (roughly 1 THB = 0.028 USD) equals $28. Through DCC, that same terminal might quote you 1 THB = 0.026 USD, giving you only $26. That extra $2 vanishes into the operator's pocket.
Where DCC Scams Hide: The 5 Most Common Locations
ATMs in Tourist Areas
Airports, train stations, and popular neighborhoods often use independent ATM operators who aggressively push DCC. Bangkok's Suvarnabhumi Airport, [London](/resources/countries/united-kingdom) Heathrow, and Rome Termini are notorious.
Restaurant Terminals
When servers bring card readers to your table—especially in [Spain](/resources/countries/spain), [Portugal](/resources/countries/portugal), and [Italy](/resources/countries/italy)—DCC offers appear. You're relaxed, hungry, less careful.
Taxis & Ride-Share Terminals
Handheld payment devices in cabs (think London black cabs, Paris taxis, [Japanese](/resources/countries/japan) rides) are DCC goldmines. Drivers benefit from the markup and push the button.
Currency Exchange Kiosks
These ARE the scam. Every "best rate guaranteed" kiosk in airports is legally allowed to charge massive markups. Avoid entirely.
Hotel Front Desks
When hotels offer to charge your room in USD or GBP instead of local currency, they're using DCC. Always ask for local currency.
Casinos & Nightclubs
High-value transactions in venues with alcohol involved = minimal scrutiny. [Macau](/resources/countries/macau) casinos and Bangkok clubs are particularly aggressive.
The Exact Phrases to Say: Your DCC Defense Script
When a terminal or ATM screen shows a currency conversion offer, here's what to do:
At ATMs: The Button to Press
Screen says: "Convert to [your currency] at a guaranteed rate?"
You say nothing. Press "NO," "DECLINE," or "REJECT." If the ATM is in a language you don't recognize, look for the left button (usually "No") or the red button. Ask a staff member: "Which button means I don't want conversion?"
The screen will likely ask again: "Are you sure?" Press "YES" to confirm. Your withdrawal will process in local currency, and your bank will convert it fairly.
At Card Terminals (Restaurants, Shops, Hotels)
Terminal shows: "Pay in USD/GBP/EUR or local currency?"
Say to the server/cashier: "Local currency, please." Or if you prefer to be cautious: "I do not want dynamic currency conversion. Please process this in [local currency]."
If the terminal is already processing and shows a conversion rate, ask the server: "Can you cancel this transaction and run it again in local currency?" Most will.
At Taxi/Ride-Share Card Readers
You say BEFORE handing over the card: "Please process this in local currency only. No currency conversion."
If the driver insists the terminal "doesn't have that option," ask for cash. You can usually find an ATM in the destination or decline the ride.
At Hotel Check-In
Hotel offers: "Would you like to be charged in your home currency for your convenience?"
You say: "No thank you. Please charge everything in [local currency]." This protects not just your room charge but minibar, restaurant, and incidental charges.
At Currency Exchange Counters
Best phrase: "No thank you. I'll use my bank card at an ATM instead." Then leave. Don't even ask for a quote.
Look for words like "guaranteed rate," "conversion," "your currency," or your home country's currency code. These are red flags.
Even if you don't understand the language, look for buttons with the local currency code (THB, EUR, GBP, etc.). Tap that.
Ask an employee to help you restart the transaction. Don't complete a purchase you don't understand.
Verify the transaction shows the local currency amount, not your home currency. If wrong, report it to your bank within 48 hours.

The Best Banks & Cards for Avoiding DCC
Some banks and cards are designed specifically to minimize foreign transaction fees and DCC exposure. Check our full guide on travel money & cards for detailed reviews, but here are the standouts:
Best for ATM Access:
- Charles Schwab Investor Checking (no ATM fees worldwide, strong exchange rates)
- Wise (formerly TransferWise) account with physical debit card
- Local bank partnerships (ask your bank which foreign banks refund ATM fees)
Best for Card Purchases:
- Capital One Venture X (no foreign transaction fees)
- Chase Sapphire Preferred (1.25x points on foreign purchases, no FX fees)
- Amex (generally good rates, clear fee structure)
Avoid:
- Banks that charge 3%+ foreign transaction fees (most traditional banks)

- Prepaid travel cards (often load DCC onto the card itself)
Checklist: Your DCC Prevention Protocol
What to Do If You've Already Been Hit by DCC
You realize you got DCC'd. Don't panic—you may be able to get your money back.
-
Check your statement immediately. Look for the transaction. Note the amount charged in your home currency vs. what you should have been charged.
-
Contact your bank within 48 hours. Tell them: "I was charged through dynamic currency conversion at [location]. This was not authorized. I request a chargeback and refund of the markup." Many banks will fight this for you.
-
Provide documentation: Your receipt, the location of the transaction, and the conversion rate you were charged (on the receipt) vs. the true mid-market rate (use XE.com or OANDA to look up historical rates).
-
Escalate if needed. If your bank denies the chargeback, ask to speak with the fraud department. DCC disputes have been won in small claims court, particularly in the EU and UK.
-
Report to authorities:
- UK FCA (Financial Conduct Authority)
- European Banking Authority (EU)
- CFPB (United States)
If you're in the EU, you have strong protections under the Payment Services Directive—banks must refund DCC transactions if you didn't explicitly consent.
DCC in Popular Destinations: What to Watch For
Different countries have different levels of DCC prevalence:
Highest DCC Risk: Thailand, Philippines, Mexico, Macau, Spain
These destinations see the most aggressive DCC offers, particularly at tourist-heavy ATMs. Bangkok airport ATMs are particularly notorious—some charge 7-8% markups.
Moderate Risk: Japan, India, Portugal, France, Australia
DCC is common in tourist areas (Shibuya, Colaba, Lisbon center) but less aggressive in residential neighborhoods. Local ATMs tend to be better than airport ATMs.
Lower Risk: Germany, Canada, Scandinavian countries
Strict banking regulations and less aggressive merchant behavior. Still be cautious, but fewer scams overall.
Essential tip for Southeast Asia: Use 7-Eleven ATMs and Bangkok Bank ATMs in Thailand—they have lower DCC rates than independent operators.
One More Thing: The "Guaranteed Rate" Lie
"Guaranteed rate" doesn't mean you get a good rate. It means the rate is locked in—locked in their favor.
ATMs often advertise "guaranteed rates" or "locked rates." This is marketing. Here's why:
- Your bank's rate is also "guaranteed"—the moment the transaction clears, that exchange rate is fixed.
- The ATM operator's "guarantee" just means they won't apply an additional fee after the transaction. The poor conversion rate IS the fee.
- A truly competitive rate would match or beat mid-market—DCC rates never do.
The word "guaranteed" creates a false sense of security. Ignore it and choose local currency every single time.
FAQ
Q: My bank charges a 2% foreign transaction fee. Isn't that the same as DCC?
No. Your bank's fee is transparent and applied to the real exchange rate. A 2% fee + true mid-market rate is usually better than a 5% markup through DCC. Additionally, your bank fee covers operational costs; the ATM operator's DCC markup is pure profit.
Q: Will declining DCC cause the transaction to fail?
No. If you decline DCC at an ATM, the transaction will complete in local currency. Your bank will convert it when it posts to your account. It won't fail.
Q: Can I dispute a DCC transaction weeks after it happened?
Yes, but it's harder. File within 60-120 days of the transaction. Your bank needs time to investigate. After 6 months, most banks won't reopen the case. Act fast.
