Using Foreign Cards in Korea

Most Korean shops take Visa and Mastercard, but subway and bus gates don't accept foreign cards yet; since March 2026 Seoul's new subway machines sell tickets on foreign cards (about 3.7% fee). Pay in won, not your home currency.

Can I use Visa or Mastercard in Korea?

Yes, in most places. The Korea Tourism Organization (VisitKorea) says hotels, department stores and general shops widely accept cards, including Visa, MasterCard and American Express, even for small purchases. A few small family-run businesses don't take cards and some stores may not offer card payment, so check before you buy.

Why doesn't my foreign card work at subway and bus gates?

Korean transit readers use a domestic standard (PayOn), not the international EMV contactless standard. Seoul City says tourists still have to buy a separate transit card and cannot tap a foreign credit card at the gates, partly because replacing every reader is costly. On Sept 17, 2026 Tmoney signed an agreement with Visa, Mastercard, UnionPay, JCB and Hana Card to build EMV "open-loop" transit payment, with development and testing by the end of 2026 and rollout starting on Seoul city buses in 2027, then Incheon buses and airport buses.

Can I buy subway tickets or a Climate Card with a foreign card?

Yes, since March 17, 2026. The 440 new transit-card machines in 273 stations on Seoul Subway Lines 1–8 accept foreign-issued credit and debit cards (Visa, Mastercard and others) for single-journey tickets, buying a Climate Card and loading short-term passes (1, 2, 3, 5 and 7 days). Foreign-card purchases and top-ups carry an average 3.7% service fee; the 30-day pass is not included yet.

Can I top up a Tmoney card with a foreign credit card?

Don't count on it for a physical Tmoney card; cash is the safe option. Tmoney's official guide says cash top-up is the most reliable method at convenience stores and many subway stations. The foreigner-only Mpass card can only be bought with Korean won cash. Seoul City says Android users can top up with a foreign card in Tmoney's Korea Tour Card app.

Should I pay in Korean won or my home currency?

Pay in Korean won (KRW). Being offered your home currency is called dynamic currency conversion (DCC). Visa says the DCC price includes the exchange rate and extra fees and often carries a 3–5% markup, so paying in local currency usually costs less. Visa requires merchants to show both amounts, the rate and the markup, and to let you choose; if those details are missing or you feel pressured, Visa recommends declining and telling your card issuer. Declining DCC does not stop the payment.

Can I use Apple Pay for the subway in Korea?

Yes, by adding Tmoney to Apple Pay, but it works only for transit and top-ups mostly use Korean payment methods. Tmoney says Apple Pay Tmoney launched on July 22, 2025; with Express Mode on you tap your iPhone or Apple Watch at the reader, but it can't be used in shops or online. Creating it in the Wallet app requires a Hyundai Card for the first top-up; in the Mobile Tmoney app you can top up by bank account, KakaoPay, Naver Pay or mileage, and the official guide does not list foreign credit cards.

Which transit card should a tourist get, and can I get my balance back?

The main options are Tmoney, EZL, WOWPASS and the Climate Card, and most balances are refundable. VisitKorea says Tmoney and EZL are sold at convenience stores nationwide; WOWPASS is a foreigner-only card bought with a passport (₩5,000) and loaded with won or foreign currencies such as USD, JPY and CNY at its kiosks; the Climate Card costs ₩3,000 and gives unlimited rides on Seoul buses and subways.
