Cards, ATMs and cash in South Korea: what to expect
Yes — cards are accepted almost everywhere in South Korea, including convenience stores, taxis and market stalls, so treat cash as a backup rather than your main money. Carry a T-money transit card and about ₩50,000 in won for the exceptions: some traditional markets, small stalls and rural buses. Use a Global ATM at a bank or convenience store, and always choose to pay in won, not your home currency.

Details
South Korea runs on cards. Seoul, Busan and every other city on the subway network take contactless payment in convenience stores, chain cafés, restaurants, taxis and even many market stalls. If your card is Visa or Mastercard, you will rarely be stuck. American Express and Discover are less reliable outside hotels and big chains, so carry a Visa or Mastercard as your main card.
The practical setup for a trip is: one contactless credit card for everyday spending, one debit card for ATM withdrawals, and a T-money transit card topped up with cash. T-money works on subways and buses nationwide and in most convenience stores; you buy it at a convenience store for a few thousand won and load it there. Some newer readers accept contactless bank cards directly on the subway, but T-money is the version that works everywhere.
Cash still has a role. Traditional markets such as Gwangjang in Seoul or Jagalchi in Busan often prefer cash at small stalls, and some rural buses and taxis outside the big cities may not take a foreign card. Around ₩50,000–100,000 in small notes covers a few days of market food, a rural bus fare and a backup taxi. You do not need to carry large amounts; ATMs are everywhere.
ATMs are the one place where South Korea can trip you up. Many machines at older bank branches only accept domestic cards and will reject a foreign one without explanation. Look for a machine labelled Global ATM or Global Service, usually at major bank branches (KB, Shinhan, Woori, Hana, NH), at Incheon and Gimpo airports, and inside 7-Eleven, CU and GS25 convenience stores, which are open 24 hours. English menus are standard on these machines.
Fees are modest but add up. Korean banks commonly charge about ₩3,000–4,000 per foreign-card withdrawal, and your own bank adds its own fee and possibly a foreign transaction charge. Withdrawing larger amounts less often is cheaper than many small withdrawals. Limits vary by bank and card, often somewhere between ₩100,000 and ₩1,000,000 per transaction; if you need more, make a second withdrawal.
One rule saves money every time: pay and withdraw in Korean won. When an ATM or card terminal offers to convert the amount into your home currency, decline — that is dynamic currency conversion, and its exchange rate is worse than your bank's. Choose 'without conversion' or 'in KRW'.
Mobile payment is widespread among locals but less useful for visitors: KakaoPay and Naver Pay need a Korean phone number and bank account. Apple Pay and Google Pay work where the terminal accepts contactless, which is most chain shops, but a physical card is still the safer default.

Tips
Tell your bank you are travelling if it still requires it, and check whether your card charges a foreign transaction fee — some US cards waive it, many do not.
Withdraw a larger amount once or twice rather than small amounts often; the fixed fee per withdrawal is what hurts.
Keep the receipt from an ATM until you see the transaction on your statement, in case a machine fails mid-withdrawal.
If a machine rejects your card, do not keep trying the same one; move to a Global ATM at a different bank or a convenience store.
Carry a second card from a different network (for example a Mastercard if your main card is Visa) as insurance against a blocked or damaged card.
T-money balances are refundable at convenience stores for a small fee, so do not over-load it on your last day.
Questions people ask
Are credit cards widely accepted in South Korea?
Yes. Visa and Mastercard work almost everywhere in cities — shops, cafés, restaurants, taxis, subway ticket machines and convenience stores. American Express and Discover are less reliable outside hotels and large chains, so carry a Visa or Mastercard as your main card.
Which ATMs have the lowest fees in South Korea?
Global ATMs at major banks (KB, Shinhan, Woori, Hana, NH) and inside 7-Eleven, CU and GS25 stores accept foreign cards and typically charge about ₩3,000–4,000 per withdrawal (2026 estimate). Your own bank's fee applies on top, so withdraw larger amounts less often.
Should I pay in local currency or my own?
Always choose Korean won. If an ATM or card terminal offers to convert the amount into your home currency, decline it — that is dynamic currency conversion, and its rate is worse than your bank's. Select 'without conversion' or 'in KRW'.
Do I need cash in South Korea?
Not much, but some. Around ₩50,000–100,000 in small notes covers traditional market stalls, small rural shops and older taxis that may not take a foreign card. Everything else can go on a card.
Can I use Apple Pay or Google Pay?
Often, yes, where a terminal accepts contactless payment — most chain shops and many restaurants. KakaoPay and Naver Pay are common among locals but need a Korean phone number and bank account, so they are not practical for most visitors.
