How to Pay in Korea: Credit Cards, Cash, WOWPASS, ATMs, and Mobile Pay

Korea is card-friendly, but one method is not enough.

Most shops and taxis take foreign Visa or Mastercard. Markets, some kiosks, and plain T-money top-ups still need cash or a domestic-style prepaid card.

Confirm foreign-transaction rules with your bank before you leave.

Quick answer: what to bring

You do not need every row. Two or three of these cover almost every payment friction.

When each method wins

Using a foreign card

Tap-to-pay with a foreign Visa or Mastercard works in most chain stores, restaurants, convenience stores, department stores, and taxis.

American Express is accepted less widely, and some terminals that read the chip will still decline a foreign card on certain networks.

Tell your bank you are traveling so a first foreign charge is not blocked as fraud, and check your foreign-transaction fee. It is commonly around 3%, but it varies by card and issuer, and some travel cards waive it entirely.

When you still need cash

Cards cover most of Korea, but keep some won for the places that lean cash-first:

• Traditional markets, street-food stalls, and some small or older restaurants.
• A few independent taxis and tiny shops that are cash- or local-card only.
• Temples, rural areas, and small entrance fees.
• Splitting a bill informally with friends.

You rarely need a large amount, a modest buffer of cash handles the gaps while your card does the heavy lifting.

Topping up a transit card

Topping up an ordinary T-money card still means cash. Load it at any convenience store. That is the dependable route and it has not changed.

What did change in 2026 is narrower than it sounds, and the distinction is the thing people get wrong. Seoul installed 440 machines across 273 stations on Lines 1 to 8 that accept an internationally issued Visa or Mastercard, plus Kakao Pay and Naver Pay.

Those machines sell three things: a Climate Card, a short-term Climate Card pass (1, 2, 3, 5 or 7 days), and a single-journey ticket. An average service fee of about 3.7% applies on an overseas-issued card.

They are not a way to recharge a plain T-money card, and 30-day passes are not included either. If your card is T-money and you want more balance on it, that is still cash.

The limit is a network boundary rather than luck: Lines 1 to 8 are the Seoul Metro-operated network.

Other operators' lines and the suburban stretches are outside it, so "is there a machine at this station" is the wrong question. The right one is which line you are on.

The T-money card guide covers buying, charging, and refunds in detail.

Foreigner prepaid cards (WOWPASS and similar)

A foreigner prepaid card solves a specific, real problem. Cards like WOWPASS let you load Korean won (and they include T-money for transit), and because the payment network reads them as a domestic card, they work at machines where a foreign Visa is often rejected: for example, the self-order kiosks at many budget restaurants and some ticket machines. That single property is the main reason visitors pick one up.

WOWPASS is the best known, but it is not the only option: AmazingPay, the Korea Tour Card, and other foreigner prepaid or tour cards offer similar prepaid-and-transit features, so compare what fits your trip rather than assuming one brand. Fees for loading and currency exchange, refund rules, and where you can reload differ between them and change over time, so check the current terms on the provider's official site before you rely on one.

Using ATMs

If you need cash, ATMs are straightforward:

• Airport ATMs are the easiest first stop and are used to foreign cards.
• In the city, look for ATMs marked as accepting global/foreign cards (often labeled "Global ATM"); machines that generally play well with foreign cards are common in tourist areas, convenience stores, and bank lobbies.
• Watch the fees: your home bank's withdrawal fee plus a local ATM fee can stack up, so fewer, larger withdrawals usually cost less than many small ones.
• Use a debit card for cash, not a credit card, a credit-card cash advance typically starts accruing interest immediately. Confirm your card's cash-withdrawal terms before you travel.

Mobile pay and Apple Pay

What works depends heavily on the terminal and your card:

• Apple Pay generally works where there is an NFC terminal, using a foreign Visa or Mastercard added to your Wallet. NFC terminals are still not universal in Korea. But they are common in the places tourists visit most: convenience stores (CU, GS25, 7-Eleven, Emart24), chain cafes such as Starbucks, department stores, and large marts.

American Express can be blocked at some merchants even where NFC exists. Treat Apple Pay as a useful backup that works well in those spots, not as something to rely on everywhere.

• Local apps (Naver Pay, Kakao Pay, Samsung Pay) generally require a Korean phone number, bank account, or resident registration, so they are usually out of reach for short-term visitors.
• QR payments (Alipay+, GLN) work only through certain countries' banking apps; check whether yours is supported.

Markets, stalls, and small eateries

At a market or a tiny restaurant, assume cash first and ask about cards before you order. A quick question saves an awkward moment at the counter.

Taxis and the airport

Most taxis take contactless cards and T-money, but a few independent drivers prefer cash, so keep a small amount handy, especially late at night. At the airport, ATMs and currency counters are easy to find on arrival, and the rail and bus links into the city accept transit cards.

Delivery apps

Food-delivery apps have historically needed a Korean card or bank account, and that is still the safe assumption.

Payment options on these platforms have been changing through 2026, so check what yours actually accepts rather than trusting either answer. If you are planning a Han River picnic or a night in, the reliable route is to buy from a convenience store or order takeout in person rather than counting on an app.

Exchanging money

You do not need to exchange a large sum in advance. A common approach is to bring a backup amount of cash and withdraw won from ATMs as you go, or load a foreigner prepaid card. In-city exchange booths and bank counters exist if you prefer cash, but rates and fees vary, so compare before changing a big amount.

Bringing cash and goods through Korea Customs

Payment setup and arrival customs are different systems. Declaration is a reporting step, not a tax on your bank balance.

Cash and other means of payment

Korea Customs Service's passenger guide lists means of payment, etc. exceeding US$10,000 among goods that must be declared (citing the Foreign Exchange Transactions Regulations). That is a declaration threshold, not a ban on carrying more money and not a customs duty charge.

• Confirm the live wording on the Customs English passenger guide before you travel: what counts as "means of payment" can include more than banknotes alone.
• Entry and exit rules for foreign exchange reporting can differ by instrument and direction; if you are near the threshold, use the official form or ask a Customs officer rather than guessing.
• Declaring cash is not the same as paying VAT, buying duty-free, or claiming a tourist tax refund.

Goods you bring into Korea (personal effects)

Separately from cash, the same Customs passenger guide currently frames a general tax-exemption allowance of about US$800 of total taxable value for goods. Agricultural, livestock, and fishery products have additional weight and KRW limits. Alcohol (up to about 2 L and US$400), cigarettes (200 sticks), and perfume (100 ml) are listed apart from that general goods allowance. Minors under 19 (by year of birth) do not get liquor or cigarette exemptions under that text.

Exceeding allowances is a reason to declare. Voluntary declaration is described with a duty reduction relative to non-declaration; do not treat blog fine amounts as fixed law. Prohibited and restricted items (for example certain foods, animals, weapons, or CITES goods) must meet clearance rules regardless of value.

Tourist tax refund on Korean shop purchases is a different program again. See the Korea tax refund guide for eligibility and paths.

Common mistakes to avoid

• Choosing your home currency at the terminal (DCC). When a card machine or ATM asks whether to charge in Korean won or your home currency, paying in won is usually better, because your own card issuer sets the exchange rate instead of the merchant's markup. Follow your card issuer's guidance if it differs.
• Relying on a single card. One decline, fraud flag, or lost card can strand you. Carry a backup.
• Using a credit card for ATM cash. That is a cash advance, with interest from day one.
• Ignoring foreign-transaction fees. They add up; know your card's rate before you go.
• Assuming kiosks take foreign cards. Many self-order kiosks don't. This is exactly where a prepaid card or cash helps.
• Mixing cash declaration with tax or duty-free shopping. Reporting money above the Customs threshold is not a tax refund, and the US$800 goods allowance is not a shopping tax-free rule.

Suggested setup by traveler type

This is a starting point, not a rule: adjust to how and where you plan to spend, and verify card support with your bank.

Frequently asked questions

Do I need cash in Korea?

Less than you might think, but yes, keep some. Cards cover most places; markets, stalls, and a few small shops still prefer cash.

Will my foreign credit card work?

Usually, especially Visa and Mastercard at chains, restaurants, and taxis. Acceptance is lower for Amex and at some kiosks. Confirm international use with your issuer.

Does Apple Pay work in Korea?

It works where there is an NFC terminal (common at convenience stores, chain cafes, department stores, and large marts) using a foreign card in your Wallet. It is not yet universal, so keep a physical card too.

What is WOWPASS and do I need it?

A foreigner prepaid card that loads won and includes T-money. It is read as a domestic card, so it works at kiosks that reject foreign cards. Helpful but optional.

Can I use Samsung Pay, Naver Pay, or Kakao Pay?

Generally no for short-term visitors: they need a Korean phone number, bank account, or resident registration.

Can I pay for the subway with a foreign card?

Not at the gate: tapping in still needs a transit card. At a machine on Lines 1 to 8 an overseas Visa or Mastercard buys a single-journey ticket or a Climate Card, with a fee of about 3.7%.

Recharging a plain T-money card is still cash.

Can I use food-delivery apps?

Assume you need a Korean card or account. Some platforms have been adding overseas-card options during 2026, so check the app before you rely on it, and buy in person if it will not take yours.

Should I exchange money before arriving?

Only a small backup amount. ATMs and prepaid cards usually give convenient rates once you are in Korea.

Won or home currency at the card machine?

Choose won. Letting your own card convert (instead of the merchant) usually avoids a worse exchange rate.

Are there foreign-transaction fees?

Often around 3%, but it depends on your card; some travel cards waive it. Check before you go.

Final recommendation

Korea makes it easy to pay by card. But the travelers who never get stuck are the ones who carry a couple of options: a foreign card, a little cash, a transit card, and, if your trip involves kiosks or budget eateries, a foreigner prepaid card. Set up the basics on arrival with the essential travel apps and a T-money card, and confirm the details that matter to your wallet with your own bank, because payment rules in Korea keep changing. For how much ground money to plan before you open the wallet, use the Korea trip budget guide.
