Paying in Korea: Foreign Cards, Cash and What Still Needs Won

Quick answer
- Credit cards are widely used — the Korea Tourism Organization names Visa, Mastercard and American Express — but check that each shop accepts your card, and carry some won for cash-only needs.
- Carry a little won anyway. A regular T-money card is topped up with Korean won cash.
- Landing at Incheon Terminal 1? The arrivals floor has currency exchange counters that are open 24 hours.
Cards are widely used in Korea. Hotels, department stores and most shops take them, and taxis accept card payment too — though no one can promise your particular card will work everywhere. The catch is the small stuff — a regular T-money top-up, the odd shop that doesn't take cards — and that's where a little Korean won saves you a walk to the ATM.

The short version
| Where | Foreign card? | Good to know |
|---|---|---|
| Hotels, department stores, most shops | Usually | Some stores don't take cards — check before you buy |
| Taxis | Usually — check before you get in | Cash, credit card or a transport card |
| Subway single tickets and Climate Card short-term passes | Yes, at the 440 new machines on Lines 1–8 | About 3.7% service fee |
| Topping up a regular T-money card at a store or station | No | Korean won cash |
| TABA taxi app | Yes | Visa, Mastercard, UnionPay, JCB |

Paying by card
The Korea Tourism Organization puts it simply: most businesses in Korea accept credit cards, from major hotels and department stores to general shops, and Visa, Mastercard and American Express can be used. It also adds a caution worth taking seriously — some stores don't provide card payment, so check before you buy.
Taxis are usually straightforward: VISITKOREA says passengers can pay with cash, a credit card or a transportation card. That's a general rule, not a promise that a particular foreign-issued card will go through, so it's worth checking as you get in.

Where won still comes in handy

The clearest case for cash is a regular T-money card topped up at a store or station. T-money's guide for visitors says you top it up by handing over the card and Korean won cash at a T-money sales location.
The subway itself has got easier. Since March 17, 2026, the 440 new ticket machines at 273 stations on Seoul Subway Lines 1–8 accept international cards such as Visa and Mastercard — for single-journey tickets and Climate Card short-term passes. Expect a service fee of about 3.7%. The former 30-day Climate Card pass is no longer available for top-up; the 1-, 2-, 3-, 5- and 7-day short-term passes continue to operate.
So if your plan is a T-money card, land with some won. If you'd rather carry as little cash as possible, the Climate Card short-term pass or single tickets are the card-friendly route on the subway.

Getting won when you land
VISITKOREA's advice is that for most tourists, the airport exchange centers are the easiest place to change money.
At Incheon Airport Terminal 1, the arrivals floor (1F) has:
- 24-hour exchange counters — Woori Bank near Exits 6 and 11, and KB Bank near Arrival Hall B
- Exchange counters open 06:00–22:00 — Hana Bank near Exit 4 and KB Bank near Exit 9
- 24-hour ATMs near Exits 4, 6, 9 and 11
The airport's directory doesn't say which ATMs take foreign-issued cards, so look at the card logos on the machine before you put your card in. This list is for Terminal 1; check the airport's facility search if you arrive at Terminal 2.
In town, banks are generally open 09:00–16:00 on weekdays, and Korea Post Bank 09:00–16:30. Hours vary by branch, and some places won't exchange old banknotes.

Taxi apps and NAVER's visitor verification
TABA is a taxi app for travelers. Its official site says you can pay with Visa, Mastercard, China UnionPay, JCB and more, sign up with an international phone number, and that it works officially with the Seoul Metropolitan Government and T-money.
NAVER introduced Passport Verification on June 4, 2026, so eligible foreign visitors can verify their identity for supported booking and ordering services without a Korean mobile number. This is separate from payment approval. NAVER's Booking/Order help lists supported overseas card networks, while some Npay services are restricted to Npay Korea Members. Check the payment options shown for your booking before relying on a particular card. (If you're still choosing how to get online, see eSIM vs SIM card vs pocket Wi-Fi — and how to use Naver Map.)

Prepaid travel cards
Some visitors use a prepaid card made for travelers. WOWPASS is one: its maker, Orange Square, describes it as an all-in-one prepaid card for foreign travelers covering money exchange, payment and transportation, and says you verify ownership in its app to withdraw a remaining balance in cash. Fees and limits change, so check the current terms in the app before you buy.

Our take

Before you fly
- Tell your bank you're travelling and check its foreign transaction and ATM fees.
- Bring a backup card, kept separately from your main one.
- Decide on your transit card — T-money (top up with won cash) or the Climate Card short-term pass (card-friendly at the new machines in Seoul).
- Note where the 24-hour exchange counters are if you land late at Incheon Terminal 1.
