Dynamic Currency Conversion: The Rules and the Fines
DCC must be opt-in and never pre-selected. Violations expose your acquirer to assessments up to USD 50,000, and e-commerce stores trigger it unknowingly.

- DCC must be optional and expressly agreed. Pre-selecting the option is named in the rules as a prohibited procedure, so a checkout defaulting to the customer's home currency is not compliant.
- In a card-present environment the information must appear on a customer-facing screen or handheld device, and the cardholder must agree by interfacing with it themselves.
- If an online store uses the payment credential to decide whether to convert the purchase amount, every DCC requirement applies. Many storefronts do this and treat it as localisation.
- You may not convert an already-approved local-currency amount after the transaction completes, and you may not represent DCC as a Visa service.
- DCC cannot be offered on cards enabled with the Visa Multi-Currency Solution or on travel prepaid cards including Visa TravelMoney.
- Visa audits for this. A violation exposes the acquirer to a non-refundable assessment of up to USD 10,000, or USD 50,000 depending on the violation, plus the Tier 2 schedule.
Dynamic currency conversion lets a foreign cardholder pay in their own currency instead of yours, with the conversion done at the point of sale. Visa permits it, regulates it tightly, and audits for it, with non-compliance assessments running to USD 50,000.
Most of the rules exist to stop one thing: DCC being applied to customers who didn't actually choose it. They're in section 5.8.9 of the Visa Core Rules and Visa Product and Service Rules (18 April 2026).
It Has to Be Opt-In, and You Cannot Nudge
The core obligation is short. A merchant offering DCC must "inform the Cardholder that DCC is optional and not use any language or procedures (for example: pre-selecting the DCC option) that may cause the Cardholder to choose DCC by default" (ID# 0003100).
Pre-selection is named explicitly. A checkout that defaults to the customer's home currency with an option to switch is not compliant, however clearly the switch is labelled. The cardholder must expressly agree.
You also cannot "impose any additional requirements on the Cardholder to have the Transaction processed in the local currency." Paying in your currency has to be at least as easy as accepting the conversion.
In Person, the Customer Has to Press the Button
Card-present DCC carries two extra requirements that a lot of terminals get wrong.
The DCC information must be displayed to the cardholder "only on a customer-facing screen or handheld Acceptance Device." Not read out. Not shown on the merchant-facing side of the terminal.
And the cardholder must "expressly agree to DCC by directly interfacing with a customer-facing screen or handheld Acceptance Device." The customer presses accept themselves. A server tapping through the currency prompt on the customer's behalf, even with a verbal yes, doesn't meet this.
Two Prohibitions Worth Knowing
You cannot convert after the fact. The rules forbid converting a local-currency amount the cardholder already approved into another currency after the transaction completes but before it enters interchange. Whatever they agreed to is what clears.
You cannot call it a Visa service. Merchants must not misrepresent, explicitly or implicitly, that their DCC service is a Visa service. It's your provider's service and your provider's exchange rate.
Some Cards Are Off Limits
Acquirers must ensure merchants don't offer DCC on cards enabled with the Visa Multi-Currency Solution, or on travel prepaid cards including Visa TravelMoney (ID# 0025740).
Those products already handle currency themselves, so converting on top of them would double up. If your terminal offers DCC indiscriminately, it's likely offering it on cards where it isn't permitted.
The E-Commerce Trap
This is the clause most online merchants don't know exists.
"If an Electronic Commerce Merchant uses a Cardholder's Payment Credential to determine eligibility to convert the purchase amount from the Merchant's currency to the Cardholder Billing Currency it must comply with all requirements relating to a DCC Transaction."
Read that carefully. If your store looks at the card number to work out where the card was issued and then offers or applies a currency conversion, you are doing DCC. All of it applies: the opt-in requirement, the no-pre-selection rule, the disclosure, the prohibition on making local currency harder.
Plenty of storefronts do exactly this automatically and think of it as a localisation feature rather than a regulated payment practice. It isn't.
The Fines Are Real
Visa may audit acquirers and their merchants for DCC compliance. Where an audit identifies a violation at a merchant outlet, ATM, or branch, the acquirer is subject to both:
- A non-refundable non-compliance assessment of up to USD 10,000, or USD 50,000 depending on the nature of the violation
- The Tier 2 general schedule of non-compliance assessments
Those land on the acquirer, which means they land on you through your acquirer. It's one of the larger named assessment figures in the rulebook, and it exists because DCC abuse is common enough to warrant it.
Multi-Currency Pricing Is a Different Thing
Worth separating, because the two get conflated.
Multi-currency pricing means you price and sell in several currencies. DCC means you price in one currency and convert at the point of sale. MCP has its own rules (ID# 0030763): don't misrepresent it as a Visa service, include the transaction currency among the displayed currencies, and if your local currency is shown, let the cardholder actually pay in it without extra hoops or pre-selection.
The anti-default principle is identical across both. Visa's consistent position is that the customer picks the currency, not the checkout.
If you sell across borders, international merchant accounts and genuine multi-currency pricing are usually the cleaner structure than bolting conversion onto a single-currency checkout.
Frequently Asked Questions
Can I default my checkout to the customer's home currency?
No. Pre-selecting the DCC option is named in the rules as exactly the kind of procedure that may cause a cardholder to choose DCC by default, which is prohibited.
Does DCC apply to online stores?
Yes, and more often than merchants realise. If you use the payment credential to decide whether to convert the purchase amount, all DCC requirements apply to you.
Who sets the exchange rate?
Your DCC provider, not Visa. You must not represent the service as a Visa service, explicitly or implicitly.
Can staff accept DCC on the customer's behalf in store?
No. In a card-present environment the cardholder must expressly agree by directly interfacing with a customer-facing screen or handheld device.
What happens if we get it wrong?
Visa can audit, and a violation exposes the acquirer to a non-refundable assessment of up to USD 10,000 or USD 50,000 depending on the violation, plus the Tier 2 general schedule.
Is DCC the same as pricing my products in multiple currencies?
No. That's multi-currency pricing, a separate mechanism with its own rules, though it shares the same prohibition on pre-selecting a currency for the customer.
