Two crowns, one strait: SEK in Malmö, DKK in Copenhagen
Malmö and Copenhagen sit 30-odd minutes apart with the Öresund between them, and they run on two currencies that share an almost identical name. Malmö uses the Swedish krona (SEK); cross the Öresund Bridge into Denmark and prices switch to the Danish krone (DKK), same word, different money, and the two do not trade one-for-one. Both descend from the 1873 Scandinavian Monetary Union, when Sweden and Denmark shared a single crown, but they have floated independently for a century, so Swedish notes are no use in a Copenhagen café and Danish notes are no use back in Malmö.
Sweden also stayed out of the euro, and euros are generally not accepted in Malmö shops or restaurants, your card just handles the conversion. In late June 2026 a krona is worth roughly €0.09, so about €1 to 11 SEK (€10 ≈ 110 SEK), which keeps the mental maths simple: knock off a zero and add a little.
Tap and go: Malmö runs almost cashless
Sweden is one of the most cashless countries on earth, only around 5% of in-person purchases are paid in cash, and Malmö follows suit. The fika counters around Lilla Torg, the museum desks, and the readers on Skånetrafiken's city buses are routinely card- or app-only and will turn a banknote away, so you can spend a long weekend here without handling a single physical krona. Visa, Mastercard, and the contactless wallets (Apple Pay, Google Pay) are accepted almost everywhere; one card with no foreign-transaction fee covers both sides of the strait.
Skip the advice to "just use Swish." Sweden's everyday payment app sits on more than 80% of Swedish phones, but it requires a Swedish bank account and a personnummer, both out of reach for a visitor, and you won't need it. On price, Malmö is mid-to-upper for Europe yet clearly cheaper than Stockholm, Oslo, or Copenhagen across the water. Budget around 47 SEK (€4) for a fika cappuccino, 128 SEK (€11.50) for a casual restaurant meal, 115 SEK for a fast-food combo, 73 SEK for a half-litre of draught local beer, and roughly 785 SEK (about €70) for a mid-range three-course dinner for two.
Crossing to Copenhagen: pay the toll, or take the train
Driving the Öresund Bridge is the priciest single item of a Malmö trip, and it is the one place the two-currency split helps you. You pay once, in your direction of travel only, at the toll station on the Swedish side at Lernacken, just outside Malmö, and the booths take DKK, SEK, EUR, and major cards (Visa, Mastercard, Amex), so there is no scramble for the right notes. A standard car up to 6 m costs 470 DKK at the booth (about €63 / 695 SEK), dropping to 420 DKK booked online and as low as 182 DKK on an ØresundGO contract, roughly a 60% saving that pays off the moment you cross more than once.
No car? The Öresundståg regional train is faster and cheaper, and it is one of Scandinavia's great short rides: straight from Malmö Central, under the strait, into København H in about 35 to 40 minutes, centre to centre with no change. Departures run roughly every 15 to 20 minutes through the day and stop at Copenhagen Airport (Kastrup) on the way, so this is also your link to CPH for flights in or out. Fares run about €7 to €13. The one rule: buy before you board, from the Skånetrafiken or Öresundståg app, oresundstag.se, or a station machine, because tickets are not sold on the train.
English, signal, and sockets: the easy part
Practically, Malmö asks very little of you. English will get you everywhere, Sweden ranks among the top handful of nations for English among non-native speakers (8th in the 2025 EF index), and menus, signs, ticket machines, apps, and staff all switch over without missing a beat, so no Swedish is needed. Connectivity matches it: strong, citywide 4G and 5G plus free Wi-Fi in most cafés and hotels, and EU/EEA visitors roam on their home plan at no extra cost.
Power is 230 V, 50 Hz on Type F (Schuko) sockets, which also take Type C and Type E, the usual continental two-round-pin plugs, so anyone arriving from mainland Europe is ready as-is, while UK, US, and other non-EU travellers should pack an adapter. One note if you are bridge-hopping: Denmark is a separate country, so confirm your data plan or eSIM covers both Sweden and Denmark before you cross, rather than discovering the gap on a Copenhagen side street.
