Yes—carry some Korean won, but do not bring your entire trip budget in bills. For most visitors, cash in Korea of KRW 50,000–100,000 (roughly US$35–70, depending on the exchange rate) is a sensible starting amount. Use an international credit card for hotels, larger restaurants, shopping, and most attractions; keep cash for transit-card reloads, small vendors, and a backup when a foreign card does not go through.
How much cash in Korea should you carry?
South Korea is one of Asia’s most card-friendly destinations. In Seoul (서울), Busan (부산), and other large cities, a Visa or Mastercard is usually more useful than a thick wallet. The City of Seoul notes that credit cards are accepted at most stores, restaurants, hotels, and tourist destinations nationwide.
| Travel situation | Practical amount | What it covers |
|---|---|---|
| Short Seoul or Busan stay | KRW 50,000–100,000 | Transit reloads, snacks, markets, and emergencies |
| One-week multi-city trip | KRW 100,000–200,000 | More small-town stops, taxis, and backup spending |
| Rural areas, islands, or hiking trips | KRW 200,000+ | Extra flexibility where payment options may be limited |
These are working amounts, not a reason to withdraw everything at once. Carry several KRW 1,000, 5,000, and 10,000 notes. A KRW 50,000 bill is accepted, but it can be inconvenient for a very small street-food purchase.
When cash in Korea still makes travel easier
The most common need is a physical T-money transit card. The card itself generally costs about KRW 3,000–5,000 before any stored value is added. It works on subways and buses, in many taxis, and at participating convenience stores. Standard card reloads are commonly cash-based, so do not rely on an overseas card to top up your balance. The official visitor guidance for transportation cards recommends loading only what you expect to use, since unused-balance refunds can involve fees and limits.
Cash is also handy at traditional markets, independent food stalls, coin lockers, and occasional small businesses. Many will accept cards, but a card reader may be unavailable or a foreign card may be declined. Tipping is not customary in South Korea, so do not set aside cash for routine restaurant or taxi tips.
Use a card for reservations and major expenses
Pay by card for accommodation, department stores, chain cafés, museums, KTX train tickets, and larger taxi fares. Keep a second card separate from your main wallet. For online bookings, use the official operator or a foreigner-friendly platform when possible: some Korean-only reservation sites require local phone verification or a Korean-issued card even when the business accepts foreign cards in person.
When a terminal or ATM offers to charge you in US dollars, choose KRW instead. This avoids dynamic currency conversion, which can use a poorer exchange rate. Tell your bank before departure if it blocks overseas transactions, and check foreign-transaction and cash-withdrawal fees.
Getting won without carrying too much
Exchange or withdraw only enough for your first day, then get more if necessary. At Incheon International Airport (인천국제공항), you can use 24-hour ATM and currency-exchange facilities, although individual bank-counter hours vary. Look for an ATM displaying an international network logo, and use a bank branch or major convenience-store ATM rather than an unfamiliar standalone machine.
- Keep cash split between your wallet and a secure bag or hotel safe.
- Before leaving the airport, make sure you can pay for your first transit ride and a snack.
- Save ATM receipts until you confirm the withdrawal and exchange rate in your banking app.
Bottom line: cash in Korea is a backup tool, not your main payment method. Start with KRW 50,000–100,000, keep your T-money balance modestly topped up, and use a no-foreign-fee card for the rest. Payment practices and airport counter hours were checked on August 12, 2026; confirm your bank’s fees and your arrival terminal’s services shortly before flying.
