When a terminal offers your home currency, it may be offering dynamic currency conversion, or DCC. Choosing local currency usually lets your card issuer or network handle conversion instead. Compare the terms rather than assuming either option is free.
Two choices, two conversion routes
Imagine a restaurant bill of 80 EUR while your card account is in GBP. The terminal may offer to charge 80 EUR or a stated number of pounds. Choosing pounds accepts the conversion offered at the terminal. Choosing euros sends a euro transaction to your card provider, which applies its relevant conversion terms.
The familiar currency can be misleading
Seeing a final amount in pounds feels reassuring, but the convenience can come with a conversion markup. The local-currency choice is not a guarantee of no fees either: your card account may charge for foreign transactions.
What to read before accepting
- The original amount in the merchant's currency.
- The amount in your home currency.
- The offered conversion rate and any displayed markup or charge.
- Your own card provider's foreign transaction terms.
If the required details are missing or you feel pushed into one option, Visa recommends declining the conversion offer. You should be able to make an informed choice rather than having it selected for you.
A made-up example
Suppose the terminal offers 72 GBP for an 80 EUR bill. That implies 0.90 GBP per EUR. Another conversion route might produce a different amount and add a fee. Compare the total result, not just the words "guaranteed rate" or "no commission".
Our 80 EUR to GBP calculator gives a dated reference value. It is useful context, but it is not the live price offered by your card issuer.
Check your receipt
Keep the receipt and confirm the transaction currency. If it does not match the choice you made, contact the merchant and your card issuer promptly to ask how to resolve it. Avoid assuming that a later refund will use exactly the original exchange rate.
Common questions
Does declining conversion cancel the purchase?
Often it means declining the terminal's conversion while paying in local currency. Read the actual screen because wording differs; do not continue if the transaction is unclear.
Does this apply at ATMs too?
Yes, an ATM may offer a similar conversion choice. Its withdrawal fee is a separate issue and may still apply.
