Paying in Korea as a Foreigner: Cards, WOWPASS or Cash?

Short answer: In Korea, a Visa or Mastercard credit card works at most shops, restaurants, cafes, convenience stores and hotels, so you won't need much cash. The gaps are public transport (foreign cards generally don't work at subway gates or on buses, so you need a T-money-type transit card), some traditional market stalls and small street vendors, and Korean payment apps like Kakao Pay and Naver Pay, which are mostly built for people with Korean bank accounts. A prepaid tourist card such as WOWPASS can cover the awkward cases. Carry a modest amount of Korean won as a backup and you're set.

This guide walks through each option, when it makes sense, and the small mistakes that cost first-time visitors money.

Credit and debit cards: your main way to pay

Korea is one of the most card-friendly countries in the world. Locals pay by card even for a single bottle of water, so nobody will blink when you tap or insert a foreign card for a small amount.

What usually works

  • Visa and Mastercard are the safest choices and are accepted almost everywhere that takes cards.
  • American Express, JCB and UnionPay are accepted at many larger stores, department stores and hotels, but less reliably at small independent shops.
  • Contactless payment is common at chains and newer terminals, but plenty of shops still expect you to insert the card. If a tap doesn't work, try inserting.

Where cards can fail

  • Some small terminals reject cards issued abroad, even though they accept Korean cards. This is not your bank blocking you; it is the terminal's setup. Having a second card from a different network helps.
  • Online and in-app payments on Korean websites, delivery apps and some ticketing sites often require Korean identity verification. Book international-friendly versions of sites where possible.
  • Traditional markets and street food stalls increasingly take cards, but cash is still the smoother option at many of them.

Avoid dynamic currency conversion

Some terminals and ATMs offer to charge you in your home currency instead of Korean won. This "dynamic currency conversion" usually comes with a worse exchange rate. When asked, always choose to pay in KRW (won). If a receipt shows your home currency, it is worth mentioning to the cashier next time.

Tell your bank before you travel

Check that your card works abroad, what foreign transaction fees it charges, and whether your bank wants a travel notice. A card with no foreign transaction fee saves real money over a week of daily tapping.

Transit cards: the one thing you really need

Foreign-issued credit cards generally can't be used to tap through Seoul subway gates or pay on city buses. The simple fix is a rechargeable transit card such as T-money, sold at convenience stores and station machines. You top it up with cash (and at some machines by card), then tap in and out of the subway, buses and many taxis. Seoul has announced plans to accept foreign cards on public transport in the future, but until that happens, plan on a transit card.

For step-by-step help, see our T-money card guide for the Seoul subway and buses.

WOWPASS and other prepaid tourist cards

WOWPASS is a prepaid card designed for foreign visitors. You get it from WOWPASS machines found at the airport, some subway stations and hotels in tourist areas, load it by exchanging foreign cash (or with a card at some machines), and then use the balance like a regular card in shops. It also has a built-in transit function that works like T-money once you top up the transit side separately.

Why people like it

  • It solves the "this terminal doesn't accept foreign cards" problem, because it behaves like a locally issued card.
  • The exchange machines let you swap leftover foreign banknotes without going to a bank.
  • The companion app shows your balance and history, and occasionally lists partner discounts.

What to watch

  • There may be an issuance fee, and refunding the remaining balance at the end of your trip can involve rules or fees. Read the current terms on the official WOWPASS site or app before loading a large amount.
  • The payment balance and the transit balance are separate. Topping up one doesn't fill the other.
  • If your normal credit card has low foreign fees and works fine, WOWPASS is a convenience, not a must.

Other providers sell similar prepaid travel cards, and some banks and travel apps from your home country offer multi-currency cards that hold won. Compare fees and exchange rates before choosing; there is no single best option for everyone.

Cash: how much and where to get it

You can get through most days in Seoul or Busan without touching cash, but a small stash is useful for:

  • Topping up a transit card at machines that only take cash
  • Street food, market stalls and some small family-run restaurants
  • Rural areas, small guesthouses and temple donations
  • Emergencies when a terminal is down

ATMs

Look for ATMs marked "Global" or with your card network's logo. Machines inside convenience stores and at major bank branches are the easiest places to start, and many have an English menu. Not every ATM accepts foreign cards, so if one fails, try another bank's machine. As with card payments, decline any offer to convert the amount into your home currency.

Money exchange

Airport exchange counters are convenient but often not the best rate. In Seoul, licensed money changers in tourist areas such as Myeongdong are well known for competitive rates. Bring clean, undamaged banknotes; torn or marked notes may be refused.

Kakao Pay, Naver Pay and other Korean apps

You will see Kakao Pay, Naver Pay and Samsung Pay signs everywhere, but most of these services are built around Korean bank accounts, Korean-issued cards and Korean phone verification. Short-term visitors usually can't link a foreign card in the normal way. Some services have introduced options for overseas users or partnered with international wallets, and the rules keep changing, so check each app's official help pages if you want to try. For a typical trip, a physical card plus a transit card is far less hassle.

Apple Pay works at some terminals in Korea, but acceptance with foreign-issued cards is patchy. Treat it as a bonus rather than your only way to pay.

Tax refunds when shopping

Many shops for tourists display a "Tax Free" sign. Depending on the store and the amount, you may get the tax taken off at the counter with your passport, or you'll receive a receipt to claim at a refund kiosk or at the airport. Bring your passport when shopping, and check the current minimum purchase rules at the store. Our Olive Young shopping guide explains how this works at one of the most popular stores for visitors.

Tipping and splitting bills

Tipping is not expected in Korea, and it can cause mild confusion if you leave extra money on the table. Prices you see are what you pay. In restaurants, you usually pay at the counter near the exit rather than at the table. Splitting a bill by card is often possible if you ask, but in a busy place one person paying and friends settling up later is simpler.

LUMI from POPORO CITY says: "Two cards from different networks, a transit card and a little cash in a zip pocket. That's the whole system."

Quick tips

  • Pack two cards from different networks, ideally one Visa and one Mastercard.
  • Always choose to pay in won (KRW), not your home currency.
  • Get a T-money or similar transit card on day one.
  • Keep a small amount of cash for markets, street food and top-ups.
  • Carry your passport when shopping to use tax-free options.
  • Check fees and refund rules on the official site before loading a prepaid card.

FAQ

Do I need cash in Korea?

Not much. Cards work almost everywhere in cities, but a small amount of won is handy for markets, street food, some transit card machines and rural areas.

Can I use my foreign credit card on the Seoul subway?

Generally no. Foreign cards don't work at most subway gates or bus readers right now, so buy a rechargeable transit card such as T-money or use a prepaid tourist card with a transit function.

Is WOWPASS worth it?

It is useful if your card has high foreign fees, if you keep hitting terminals that reject foreign cards, or if you want to exchange leftover foreign cash easily. If your card works well with low fees, it is optional. Check the current fees and refund terms first.

Can tourists use Kakao Pay or Naver Pay?

Usually not in the full way locals do, because these apps are designed around Korean bank accounts and phone verification. Options for visitors change over time, so check each app's official help center.

Should I tip in Korea?

No. Tipping is not part of Korean culture, and service charges, where they exist, are already included in the bill.
