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"
⚠️ When you pay by card, a machine may ask whether to charge in KRW (won) or your home currency. Always choose KRW (won). Choosing your own currency triggers "Dynamic Currency Conversion," which adds a hidden markup — often 3–8% worse than your bank's own rate.
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.
