Dynamic currency conversion is when you pay abroad with a card and the shop offers to charge you in your own money instead of the local money. It sounds kind, but the shop picks the exchange rate, and it is usually a bad one. Saying “no, local money please” almost always costs less.
Let’s see it in real life…
Theo is in Copenhagen for three days with his big sister Lina. In Denmark, people pay in kroner, not euros.
At the harbor, Theo spots a wooden boat in a shop window. The tag says 120 kroner. “That is about sixteen euros,” Lina says.
At the counter, Lina taps her card. The reader asks a question: “Pay in DKK or in EUR?”
“Euros!” says Theo. “Then we know what it costs.”
Lina reads the small print: “EUR 17.10, exchange rate includes a 6% markup.” She frowns. “Sixteen became seventeen. Who gets the extra euro?”
The shopkeeper, Mr. Holm, shrugs: “The machine company. And a little bit for me. You can say no, that is the rule.”
Lina chooses “DKK”. The reader prints 120 kroner. Her bank will change it into euros itself, at a better rate.
That night, Lina shows Theo her bank note: 120 kroner became 16.05 euros. “One euro saved, just by picking the local money.”
Theo thinks about it. “So the question on the machine was a trap?”
“Not a trap. A choice. But one answer is almost always cheaper, and it is not the one that looks easy.”
The next day, at the ice cream cart, Theo reads the reader first: “Lina, it asks again. Say kroner!”
That is dynamic currency conversion.
Tiny recap
- It means… a shop abroad offers to charge your card in your own currency, at an exchange rate the shop’s machine chooses.
- It helps when… you want to see the exact amount in your money before you pay. That is the only real advantage.
- Watch out for… the markup. In Europe, the machine must print it. Picking the local currency and letting your own bank convert is almost always cheaper.
…detailed for specialists
Dynamic currency conversion (DCC) is a service that lets a cardholder paying abroad, at a terminal, an ATM or online, be charged in the card’s billing currency instead of the merchant’s local currency. The conversion happens at the point of sale, at a rate set by the DCC provider and the acquirer, which includes a markup. If the cardholder declines, the issuer converts the amount instead.
It matters in 2026 because cross-border card spending grows faster than domestic spending, because the markups dwarf interchange, and because regulators and schemes police the offer. For PSPs, PayFacs and platforms, DCC is a revenue line, a compliance obligation and a reconciliation problem at once.
What is dynamic currency conversion?
When a card issued in euros pays 120 Danish kroner, someone has to turn kroner into euros. There are two candidates.
- Issuer conversion (no DCC): the transaction is authorized and settled in kroner. The scheme converts it at its wholesale rate, and the issuer applies its own foreign transaction fee, which can be zero or several percent.
- Dynamic currency conversion: the terminal identifies the card’s billing currency from the BIN, quotes an amount in euros at a rate chosen by the DCC provider, and the transaction is authorized and settled in euros. The issuer has nothing left to convert.
The DCC rate is a reference rate plus a markup, split between the DCC provider, the acquirer and often the merchant, which is why hotels, airports and tourist shops like it. Visa tells cardholders that the home-currency option includes a conversion rate plus additional fees, so it can cost more than paying in the local currency. Mastercard’s guide defines the markup as a standalone fee added on top of the exchange rate based on a commercial agreement.
DCC is not multi-currency pricing, and not local settlement. It is the only model where the conversion is offered as a choice at the moment of payment, and the only one where the cardholder pays the markup.
How does DCC work at the terminal or online?
- BIN lookup. The terminal or gateway reads the first digits of the card and finds the issuing country and billing currency. If the card is foreign and the currency is supported, DCC is eligible. Misaligned BIN tables, as our #TheShot episode on misaligned BIN data shows, produce offers in the wrong currency.
- The offer. The screen shows the amount in the local currency, the amount in the billing currency, the exchange rate, the markup and the right to decline. In the EU, the markup must be expressed against the ECB reference rate.
- The choice. The cardholder selects a currency. The choice cannot be made for them, and the PIN comes after it.
- Authorization and clearing in the chosen currency. If DCC is accepted, the authorization carries the billing-currency amount and the DCC indicator. The issuer sees a euro transaction.
- Settlement. The acquirer settles with the scheme in the billing currency, pays the merchant in its local currency, and distributes the markup. Refunds must use the original currency. The settlement side is in settlement and payout.
What do Visa and Mastercard require?
Both schemes allow DCC under conditions. Mastercard’s 2025 merchant guide states that no specific currency conversion method may be implemented as the default option, that the cardholder must not be steered, that yes/no, accept/decline and red/green button pairs are prohibited, and that an e-commerce checkout may preselect DCC only if the shopper is clearly given the means to opt out. Receipts must show both amounts, the currency codes and the rate, whether or not DCC was chosen. DCC may not be offered on contactless payments at or below the CVM limit, nor on multi-currency and prepaid travel cards. Acquirers must register themselves and their DCC providers first, and remain responsible for fees even when a service provider runs the program.
Visa requires the same three disclosures, the amount in both currencies, the exchange rate and any markup, and states that merchants must not choose on the cardholder’s behalf or steer with font size or color. A cardholder who was not offered the choice has a dispute right: Visa condition 12.3, Incorrect Currency, applies when the cardholder was not advised or did not agree that DCC would occur, and the merchant’s only defense is evidence that the cardholder actively chose it, with the receipt. Mastercard gives issuers an equivalent right. DCC is one of the few places where a chargeback is won or lost on a screen layout.
What does EU law say about currency conversion charges?
Regulation (EU) 2019/518, since codified into Regulation (EU) 2021/1230, added currency conversion rules to the cross-border payments regulation. Since 19 April 2020, anyone offering conversion at an ATM or point of sale in the EU must express the total conversion charges as a percentage markup over the latest ECB euro reference rate, show the amount in the payee’s currency and in the payer’s currency before the payment starts, and tell the payer that they can pay in the payee’s currency instead. Since 19 April 2021, the payer’s own bank must send an electronic message with its own markup after the first card payment in another EU currency, and then at least once a month per currency, unless the customer opts out. The UK kept the same text as retained law after Brexit.
The regulation did not ban DCC or cap the markup. Its review clause asked the Commission to assess letting payers block DCC on their card altogether, an option consumer groups still push for and some issuers now offer in their apps. For a platform, an EU terminal or checkout that shows a rate without an ECB-referenced percentage is non-compliant on day one, scheme rules aside.
DCC in numbers (2026)
- Markup: Wise reports that across the DCC offers its customers accept, the average markup is around 8%, with a 12.5% example on a London ATM, and that its users fall for DCC about 1,000 times a day.
- Range: a 2022 legal review put European DCC markups between 2.6% and 12%, averaging around 5%, with a 13.7% differential measured on a Czech ATM.
- Penalties: Mastercard assessments for registration or data integrity failures run up to USD 25,000 per violation, and USD 20,000 for a failed mystery-shopping test.
- Volume: Visa’s cross-border volume grew 13% in fiscal 2025 and international transaction revenue reached $14.2 billion, up 12%.
- Scale of the DCC industry: Shift4 bought Global Blue, whose tax-refund and currency conversion technology runs in over 400,000 locations across 52 countries, at an enterprise value of about $2.5 billion.
- Risk: the EBA and ECB measured card fraud rates on cross-border payments at more than seven times the domestic rate in 2024, which is the same population of transactions DCC targets.
DCC, multi-currency pricing or local settlement: which one?
- DCC suits card-present tourism, hospitality and ATMs: the merchant stays in one currency, earns a share of the markup, and takes on a compliance program.
- Multi-currency pricing (MCP) suits e-commerce: prices are shown and charged in the shopper’s currency from the start, the merchant pays the FX cost at settlement, and there is no offer to decline. The guide to finding the right acquirer for cross-border payments covers the settlement currencies to ask for.
- Local acquiring and local settlement suit merchants with real volume in a country: domestic interchange instead of cross-border rates and scheme fees, higher approval rates, local methods, and no conversion at all. In the Nordics, where domestic debit and mobile wallets dominate, a foreign card offered DCC is the exception.
DCC: what changes for PSPs, PayFacs and platforms
Onboarding and registration
DCC is an acquirer-level program. The acquirer registers with the schemes and its DCC provider, and the platform enables DCC merchant by merchant, by MCC and by terminal. A PayFac must know which acquirers support DCC, in which currencies and under which markup contract, before promising it to a hotel chain. Our article on scaling in-store payments across countries explains why terminal fleets rarely behave the same way in two countries.
BIN data and routing
The offer starts with the BIN. A platform routing across several acquirers must send the transaction to the one whose DCC contract covers that currency, and keep BIN tables current. Where no contract exists, the fallback is local currency, never a silent conversion.
Authorization, capture and refunds
A DCC transaction is authorized and captured in the billing currency, with the DCC indicator and rate recorded. Refunds must use the original currency and, under Mastercard’s rules, the original amount or the original rate. A refund at today’s rate is a compliance finding and a complaint.
Settlement and reconciliation
Each DCC payment produces three amounts that must reconcile: local, converted and markup share. Multi-acquirer operators need all three on the transaction record, per provider, to pay out merchants correctly. That is what consolidated reporting and reconciliation is for.
Disputes and evidence
Condition 12.3 is defended with proof of choice. Store the screen version, the markup displayed and the cardholder’s selection with every DCC transaction, because issuers and mystery shoppers ask for them months later.
Pricing and revenue share
The platform’s share of the markup is real, but it is earned on transactions that already carry cross-border interchange, scheme fees and a higher fraud rate. The right pricing conversation compares DCC revenue with the savings of local acquiring, not with zero.
NORBr provides the white-label infrastructure that connects acquirers and local payment methods through one Global Payment Network, with a connector per provider, under the operator’s own brand.
Is DCC worth it in 2026?
For a tourist, almost never: the issuer’s conversion is cheaper in most cases, and EU terminals now print the markup that proves it. For an acquirer or a platform, yes, as a compliant opt-in program on card-present travel volume, with the choice, the disclosures, the refund rules and the evidence built into the terminal flow. For merchants who sell abroad every day, multi-currency pricing and local acquiring, with the right partners for expanding into new markets, return more than DCC ever will. The Payments Library report on the future of cross-border payments goes deeper.
Frequently Asked Questions
Should I pay in local currency or my home currency abroad?
Local currency, almost always. When you choose your home currency, the merchant’s DCC provider converts at a rate with a markup that averages several percent. When you choose the local currency, your own bank converts at the scheme rate plus its fee, which is usually lower. The EU terminal must show the markup.
Who earns the money from dynamic currency conversion?
The markup is shared between the DCC provider, the acquirer and often the merchant, under a commercial agreement. The card schemes and the issuer do not receive it. That is why DCC is popular in hotels, airports and tourist shops, and why PSPs and PayFacs see it as a revenue line on cross-border volume.
Is DCC legal in the EU?
Yes, with conditions. Since April 2020, Regulation (EU) 2019/518, now part of Regulation 2021/1230, requires the charge to be shown as a percentage markup over the ECB reference rate, both amounts displayed before payment, and the local-currency option offered. The markup itself is not capped. Our PSD3 episode covers the wider rulebook.
Can I dispute a DCC charge I did not agree to?
Yes. Visa dispute condition 12.3, Incorrect Currency, covers transactions where the cardholder was not advised of DCC or did not agree to it, and Mastercard gives issuers an equivalent chargeback right. The merchant must prove the cardholder actively chose the conversion, with a receipt showing both amounts and the rate.
What is the difference between DCC and multi-currency pricing?
DCC converts a local-currency price at the moment of payment, at the cardholder’s choice, with a markup the cardholder pays. Multi-currency pricing shows and charges prices in the shopper’s currency from the start, with the merchant absorbing the FX cost at settlement. Local acquiring avoids conversion entirely by settling in each market’s currency.
