Money & payments in Korea
Korea is largely cashless — foreign credit cards work in most shops, restaurants, and taxis. But there are a few situations where cash (Korean won) still matters, and one costly mistake almost every visitor makes.
Cards vs cash
- Cards work almost everywhere — big and small shops, convenience stores, taxis, most restaurants. Contactless is common.
- Keep some cash for: traditional markets, small street-food stalls, some family-run places, and topping up your T-money card.
- ATMs marked "Global" accept foreign cards. Bank ATMs may have limited hours late at night.
The DCC trap — never "pay in your home currency"
This applies to card machines and ATMs. If a screen offers "with conversion" vs "without conversion," pick without. Your bank will convert at a better rate.
Exchanging money
- Airport exchange counters are convenient but usually give the worst rates.
- Downtown exchange shops (e.g., Myeongdong in Seoul) often give noticeably better rates for cash.
- For most people, withdrawing won from a Global ATM with a low-fee card is simplest — just decline the DCC "conversion" offer.

Everyday payment apps
Once you have a Korean bank account, apps like Kakao Pay and Naver Pay make paying and splitting bills easy. Before that, your foreign card + some cash covers almost everything.

Before you fly: a five-minute card checklist
Most payment headaches in Korea are preventable at home. Run through this list the week before departure and you will probably never think about money logistics again once you land.
- Bring at least two cards on different networks — if one gets blocked or a terminal refuses it, the second usually sails through. Keep them in separate bags so a lost wallet doesn't take both.
- Check your foreign transaction fee — some cards quietly add a percentage to every overseas purchase. If yours does, treat it as the backup card, not the daily one.
- Know your PIN — a few terminals and most ATMs will ask for it, and "I only ever tap at home" is a bad discovery to make at a cash machine.
- Tell your bank you're traveling if it still uses travel notices — a fraud freeze on day one is a classic, entirely avoidable mess.
- Add a card to your phone wallet — contactless is widely accepted and noticeably faster at busy counters.
When your card gets declined anyway
Even a good foreign card fails occasionally in Korea, and it's rarely about your balance. Unattended machines are the usual culprits: some ticket kiosks, self-service cafes, and older vending machines only talk to Korean-issued cards. Korean online shopping sites are the other wall — many checkout systems expect a local card or local identity verification, and no amount of retrying changes that.
- First, simply try again, or insert the chip instead of tapping — terminals can be moody about foreign cards.
- If a kiosk refuses you, look for a staffed counter — a human with a card machine almost always succeeds where the kiosk failed.
- Keep your small cash reserve for exactly these moments; it turns a dead end into a shrug.
- For Korean websites that won't take your card, check whether there's an English or international version of the checkout — or just buy the same thing in person.
Paying like a local: small habits that smooth things out
In most casual restaurants you pay at the counter on your way out, not at the table — pick up the paper slip from your table if there is one, or just point to where you sat. And there is no tipping anywhere: not in taxis, restaurants, cafes, or hotels. Leaving extra money mostly creates confusion, and staff may chase you down to return it.
Splitting a bill works differently here too. Rather than asking staff to divide one check five ways, Koreans usually have one person pay while the others transfer their share afterward. As a visitor, the easy version is to take turns paying, or to settle up in cash among yourselves — asking a busy counter to run four cards on one bill is possible in many places, but it marks you as a table to dread.
Mistakes visitors keep making
- Exchanging a big pile of cash on arrival. Korea runs on cards, and most people end up re-exchanging leftover won at a loss on the way home. Change modest amounts as you go instead.
- Pressing "home currency" at an ATM. The DCC markup described above catches people twice — once while shopping, once while withdrawing. The answer is the same at both screens: KRW, always.
- Relying on a single card for the whole trip. A lost wallet or a sudden bank freeze shouldn't end your holiday.
- Letting coins pile up. Spend them topping up your T-money card at a convenience-store register instead of flying home with a bag of metal you can't exchange.
- Assuming every market stall takes cards. Many do now, but plenty of the best old stalls don't — carrying some cash keeps the choice yours, not theirs.
