Every guide tells you to press “SEK”. This one explains why the button exists, what the law forces the screen to show you, and what to do when a shop or ATM made the choice for you.
When you need this
A terminal is turned toward you showing two amounts and two buttons, and there’s a queue behind you. An ATM asks whether to “continue with conversion”. A hotel or car-rental desk hands back a receipt in dollars or euros. Or your statement shows a Swedish purchase already converted at a rate you don’t recognize.
What DCC actually is
Dynamic currency conversion — in Swedish dynamisk valutaväxling — is the offer to charge your foreign card in your home currency instead of kronor. The conversion is done by the merchant’s payment provider, not your own bank, and it’s offered because it earns that provider money: its margin is built into the exchange rate it quotes.
So the choice isn’t between paying and not paying. It’s between two exchange rates:
| You press | Who converts | Whose margin you pay |
|---|---|---|
| SEK (kronor) | Your own card issuer | The rate and fee in your card agreement |
| Your home currency | The merchant’s payment provider | A rate the provider sets, with its margin inside |
Swedish consumer bodies — Konsumenternas Bank- och finansbyrå and Finansinspektionen, the financial regulator — both say paying in the local currency is usually the cheapest option. In a 2021 test, Konsumenternas measured DCC mark-ups of 2.4% to 4.13% over the European Central Bank rate, against 0–2% for typical Swedish bank cards. It also warns that tourist-area ATMs, such as those at airports, can carry even worse conversion rates than other machines.
What the law requires on the screen
This is the part most pages skip. DCC isn’t illegal, but it’s tightly regulated, and knowing the rules is what lets you push back.
The EU rule. Regulation (EU) 2021/1230, Article 4, applies to any card payment in an EU currency that involves a conversion, including a kronor payment in Sweden. Whoever offers conversion at an ATM or till must:
| Requirement | Article |
|---|---|
| Express the total conversion charge as a percentage mark-up over the latest ECB euro reference rate, before you pay | 4(1) |
| Show the amount in kronor and the total in your account’s currency | 4(3) |
| Clearly display the mark-up and tell you that you can pay in kronor and let your own bank convert | 4(4) |
| Repeat both amounts and the mark-up on a receipt or other durable record | 4(4) |
| Give all of this free, neutrally and understandably | 4(7) |
If an older article cites Regulation 2019/518, that’s where these rules started: it inserted them into the old Regulation 924/2009 from 19 April 2020. That regulation has since been repealed and codified as 2021/1230, so Article 4 is the citation in force.
The Swedish rule. Sweden’s Payment Services Act (betaltjänstlagen, 4 kap. 3 §) says whoever offers conversion at the till or an ATM must tell you all charges and the exchange rate — and that the payer must approve the conversion before the transaction is carried out. A conversion you were never asked about breaks that rule.
The card-scheme rule. Visa’s own traveller guidance says merchants and ATMs must give you the choice and must not choose on your behalf, nor steer you with font size or color. Payment providers summarize the scheme rules the same way: DCC may not be the default or an opt-out, and in person you must actively select it on the screen or PIN pad.
How to read the screen
Wording differs by terminal, but a compliant DCC screen carries the same pieces:
- The price in SEK
- The same price converted into your currency
- The exchange rate used
- The mark-up as a percentage over the ECB rate
- Two choices — one in kronor, one in your currency
The ECB rate is a benchmark, published around 16:00 CET each working day and “for information purposes only”, so you can’t transact at it. It’s what the mark-up is measured against. For dollars or pounds, the reference is a cross rate derived from two ECB rates.
A worked example, using the ECB rate of 24 September 2026 (11.2645 kronor per euro): a 450 kr lunch is about €39.95 at the reference rate. With a 4% DCC mark-up — inside the range Konsumenternas measured — it’s about €41.55. Small once; not small across a two-week trip.
Watch for “guaranteed rate” or “no commission” wording. The margin sits in the rate itself, which is exactly why the law demands a percentage.
How to decline
- Before the trip, find your own card’s conversion cost. EU banks must publish their mark-up over the ECB rate; elsewhere, look for the foreign transaction fee in your card terms.
- At the terminal, read before you tap.
- Choose SEK — it may say “SEK”, “kronor”, “local currency” or “without conversion”.
- If staff chose for you, hand the terminal back and ask for kronor before you tap or enter a PIN.
- At an ATM, decline the conversion and choose to be charged in SEK.
- Check the receipt (kvitto) shows the amount in kronor.
At hotel check-out and car-rental desks, where staff often key the payment, say “kronor, please” before the card goes in. If a screen shows only your home currency, a quick photo documents that you weren’t offered a choice.
If you were converted without being asked
At the till: say so straight away and ask the merchant to cancel the payment and run it again in SEK while you’re still there. This is the fastest fix by far.
Afterwards: keep the receipt — by law it must show both amounts and the mark-up — and contact your card issuer. Visa’s guidance is to report it to the issuer when the required details were missing or you felt pressured. Whether money comes back depends on your issuer and the card scheme’s dispute rules, so we won’t promise a refund.
If a Swedish business refuses to fix it, the national consumer dispute board Allmänna reklamationsnämnden (ARN) accepts complaints in English for a 150 SEK fee, once the business has rejected your complaint or failed to answer. Its decisions are recommendations, not binding judgments.
EU cardholders get one extra safeguard: your own bank must send you an electronic message with its mark-up after a card payment in another EU currency, so you can compare. A bank outside the EU isn’t bound by that rule.
What’s changing
The EU’s new Payment Services Regulation and PSD3 reached a provisional agreement in November 2025 and final compromise texts in April 2026. Formal adoption was still pending when we checked, with the new regime expected to apply from late 2027 at the earliest. Industry summaries say currency-conversion disclosures will be tightened, but until the final text is published, Article 4 of Regulation 2021/1230 is the rule — and pressing SEK stays the answer either way.

FAQ
Should I pay in SEK or my home currency in Sweden?
Pay in SEK, every time. Choosing your home currency triggers dynamic currency conversion, done by the merchant’s payment provider at a rate that includes its own margin. Paying in kronor lets your own card issuer convert, which Swedish consumer bodies say is usually cheaper. A 2021 test found DCC mark-ups of 2.4–4.13% over the European Central Bank rate.
What does the EU rule on currency conversion require?
Regulation (EU) 2021/1230, Article 4, requires whoever offers conversion at an ATM or till to show its total charge as a percentage mark-up over the latest ECB reference rate before you pay. It must show both amounts, tell you that you can pay in the local currency instead, and repeat the details on the receipt. The rules started under Regulation 2019/518.
Is it legal for a shop to charge my card in my currency without asking?
No. Sweden’s Payment Services Act says the payer must approve the currency conversion before the transaction is carried out, and the EU regulation requires the mark-up and both amounts to be shown first. Card-scheme rules also forbid merchants and ATMs from choosing on your behalf or pre-selecting the option. Ask for the payment to be cancelled and run again in kronor.
What should I do if I was charged in my home currency by mistake?
Raise it immediately at the till and ask the merchant to cancel and re-run the payment in SEK. If that is refused or you notice later, keep the receipt and contact your card issuer; Visa advises reporting it when details were missing or you felt pressured. A dispute with a Swedish business can go to the consumer board ARN for 150 SEK.
What does “without conversion” mean on a Swedish ATM?
It means the machine charges your card in kronor and leaves the exchange to your own bank, which is the option to choose. The alternative, often worded as a guaranteed or fixed rate in your currency, is dynamic currency conversion. Airport and tourist-area machines can carry worse conversion rates than others, so decline it there especially.
Does paying in SEK avoid my bank’s foreign transaction fee?
No. When you pay in kronor your own card issuer converts, using the rate and mark-up in your card agreement, but Swedish consumer advice is that this is usually still the cheapest option. EU banks must publish their mark-up over the ECB rate; outside the EU, check your card terms for the foreign transaction fee before travelling.
