Money is one of those things that can quietly make or break the first day of a trip — and Korea has a few quirks worth knowing before you land. The good news is that Busan is an easy place to spend: it’s one of the most card-friendly cities you’ll ever visit, the ATMs are everywhere, and the whole system is fast and modern. The catch is in the details — which ATMs actually take your foreign card (only about one in five), where to change cash without losing money, the fees that sneak onto your statement, and small cultural things like tipping (don’t). This guide walks through all of it: the won and what things cost, cash versus card, the best places to exchange money, foreign cards and ATMs, hidden fees, mobile payments, tax-free shopping and tipping — with specific advice depending on where you’re coming from. Use it alongside the rest of your trip plan in our complete Busan Travel Guide.

1. The Korean won: notes, coins and what things cost

Korea’s currency is the won (₩, code KRW), and in mid-2026 it trades at roughly 1,450–1,530 won to one US dollar — but exchange rates move, so check a converter before you travel. A handy mental shortcut: at around 1,400–1,500 to the dollar, just knock three zeros off a price and it’s roughly the same number in US dollars (₩10,000 ≈ US$7).

• Banknotes: 1,000 (blue), 5,000 (red), 10,000 (green) and 50,000 (yellow) won.
• Coins: 10, 50, 100 and 500 won — you’ll mostly use 100 and 500 for vending machines and lockers.
• What things cost (rough): a subway ride ~1,600 won; a bowl of dwaeji-gukbap ~9,000–11,000 won; a convenience-store coffee ~1,500 won; a mid-range dinner ~15,000–25,000 won a head.

2. Cash or card? How Korea actually pays

Korea is overwhelmingly a card society — you can tap or swipe a Visa or Mastercard for almost anything, including a single coffee — but a little cash still smooths the edges. In practice, most travellers put nearly everything on a card and keep maybe 50,000–100,000 won in cash as backup.

• Card works almost everywhere: restaurants, cafés, shops, convenience stores, most taxis and chain stores. Nobody blinks at paying a small amount by card.
• Cash still rules in a few places: traditional markets (Jagalchi, Gukje), street-food stalls, some small or old-school eateries, temples and the odd mom-and-pop shop.
• Transit: a T-money or Cashbee card (topped up with cash) covers buses and the subway — see our transit guide.

3. Where to exchange money — and where not

The golden rule: change only a little at the airport and do the rest at a licensed money changer in the city, where rates are far better. Airport counters typically give rates 3–5% worse than downtown — on a few hundred dollars that’s real money lost.

• Best rates: the cluster of licensed private exchange shops in Myeongdong (Seoul) and, in Busan, around Nampo-dong, Seomyeon and the Gukje Market area. They post rates on the window and compete street-by-street.
• At the airport: change just enough for your airport transfer and first meal — say US$50–100 — then change the rest in the city.
• Banks also exchange currency at fair (if slightly worse) rates, and there are 24-hour automated exchange machines in some districts.
• Bring clean, large bills: crisp US$100 notes usually get the best rate; torn or marked notes can be refused or discounted.

4. Should you bring your own currency or US dollars?

Major hard currencies all exchange easily in Korea, so travellers from English-speaking countries can simply bring their own cash to change.

• US dollars, euros, British pounds, Canadian and Australian dollars are all widely accepted at Korean money changers at competitive rates — no need to convert to USD first.
• US dollars remain the single most universal option and often get the keenest rates, so if you happen to have some, they’re never wasted.
• Cards as backup: whatever you bring, a Visa or Mastercard covers you between exchanges.

5. Foreign cards and ATMs in Korea

You can withdraw won with a foreign card, but only at the right machines: look for a ‘Global ATM’ or ‘Global Service’ sign with the Visa/Mastercard logos and an English menu. Roughly only one in five Korean ATMs accepts foreign cards, so the others will simply return your card.

• Always choose to be charged in won (KRW), not your home currency — see the next section on fees.
• Airport and big hotels reliably have foreign-card ATMs if you need cash on arrival.

6. The fees nobody warns you about

The biggest avoidable cost in Korea isn’t the exchange rate — it’s the fees, especially ‘dynamic currency conversion’ (DCC). When a card machine or ATM asks whether to charge you in won or in your home currency, always choose won; choosing your home currency lets the machine apply a poor conversion rate and a markup.

• DCC: at shops and ATMs, pick KRW every time. Paying “in dollars” (or pounds, euros…) almost always costs more.
• Foreign transaction fees: many cards add ~1–3% on overseas spending. A travel card with no foreign-transaction fee pays for itself on a trip.
• ATM fees: the ~3,600-won machine fee plus your bank’s withdrawal fee can add up — withdraw a sensible lump sum rather than lots of small amounts.
• Exchange spread: the rate itself is a cost; city changers beat airports and most banks.

7. Mobile payments and transit cards for foreigners

Korea runs on slick local payment apps — but most of them need a Korean bank account and phone number, so foreign visitors usually can’t use them. Don’t worry: your physical card and cash cover everything.

• Korean apps (Naver Pay, Kakao Pay, Toss, Payco): generally off-limits to short-term visitors, as they require local banking.
• Alipay+ and WeChat Pay: increasingly accepted at shops via nationwide QR rollouts, useful if you already use them (especially handy for travellers from parts of Asia).
• Transit cards: a T-money or Cashbee card is the simplest way to ride; buy and top up with cash at any convenience store. Some Seoul Metro kiosks now also sell T-money to foreign Visa/Mastercard/JCB/UnionPay/Amex cards.

8. Tax-free shopping: get up to ~8% back

Foreign visitors can reclaim most of Korea’s 10% VAT on shopping — a net refund of around 5–8% — as long as you shop at ‘Tax Free’ stores and follow the steps.

• Who & minimum: tourists staying under six months, on purchases of ₩15,000 or more per store, per transaction. Bring your passport every time you shop.
• Immediate refund: at shops with a ‘Tax Free’ logo, show your passport at the till and the tax is deducted on the spot (common for smaller purchases).
• Airport refund: otherwise, keep your receipts and the goods unopened, then get a customs check and use the refund kiosks at the airport before you check in.
• Rules: keep items unused/unopened in Korea, and leave the country within three months of purchase.

9. Tipping in Korea: you really don’t

Tipping is simply not part of Korean culture — it’s not expected in restaurants, taxis, hotels or salons, and staff are paid a proper wage. Leaving extra can even cause mild confusion or embarrassment, so the easy, correct move is not to tip.

• Restaurants & cafés: pay the bill as shown; no tip, no service charge to add.
• Taxis: round up if you like, but it isn’t expected; drivers won’t chase you for change.
• The one exception: international tour guides who often host foreign visitors will appreciate a thank-you — around 10,000–20,000 won for a half- or full-day tour, ideally in a small envelope handed with both hands.

10. A money game plan for Busan — and the verdict

Here’s how to handle money for a typical Busan trip, start to finish.

1. Before you flyTell your bank you’re travelling, set a 4-digit PIN, and pack a no-foreign-fee card plus some clean home-currency cash.
2. At the airportChange just US$50–100 (or equivalent) for the airport bus and a first meal; buy a T-money card at a convenience store.
3. In the cityChange the rest at a Nampo-dong, Seomyeon or Gukje Market money changer for a better rate.
4. Day to dayTap your card for most things, keep ~50,000 won cash for markets and street food, and always choose to be charged in won.
5. Before you leaveSpend down or re-exchange leftover won (it’s hard to change abroad), claim your tax refund, and declare if you’re carrying over US$10,000.

Verdict: money in Korea is genuinely easy once you know the four rules: tap your card freely, change cash in the city not the airport, use ‘Global ATM’ machines and always pay in won, and don’t tip. Do that and you’ll spend less on fees, never get stuck without cash at a market, and keep more of your budget for the food and the fun.
