How to Pay in Korea: Cash, Cards & Exchange Guide (2026)
⚡ Quick answer
- Bring a Visa or Mastercard with no foreign transaction fee. Your foreign card works at roughly 90–95% of places tourists actually go — restaurants, cafes, hotels, convenience stores, department stores.
- Carry ₩50,000–₩100,000 in cash. Not for everyday spending, but for traditional markets, street food carts, and small local eateries that still refuse cards.
- Transit is the one real problem — and it got much easier in March 2026. Seoul Metro kiosks now take foreign cards, and iPhone users with a Mastercard can load T-money into Apple Wallet.
- Best exchange rates: money changers in Myeongdong or Namdaemun. Worst: the airport counter and your bank at home.
- Never let a card machine charge you in your home currency. Always choose Korean won. This single habit saves 3–6% on every transaction.
Figuring out how to pay in Korea trips up more first-time visitors than visas, language, or transport — because Korea sits in an awkward middle zone. It is not Japan, where cash still rules half the country. It is not Sweden, where cards work everywhere without thinking. Korea is aggressively digital, deeply card-friendly, and yet there are specific moments — a subway gate at 11pm, a tteokbokki cart in Gwangjang Market, a self-order kiosk at a fried chicken place — where your perfectly good Visa card will simply be refused.
This guide covers exactly what to bring, what to set up before you fly, where to exchange money, and how much cash you actually need. Everything here reflects the rules as of 2026, including the payment changes that landed in March and April of this year and made a lot of older advice obsolete.
What Changed in 2026 (Read This Before Any Older Guide)
If you have been reading Reddit threads or blog posts written before 2026, discard the section about transit. It is out of date. Three things changed in quick succession:
March 17, 2026 — Seoul Metro kiosks opened to foreign cards. New ticketing machines at hundreds of subway stations now accept international Visa, Mastercard, JCB, UnionPay, and American Express for buying single-journey tickets, purchasing T-money cards, and topping up the Climate Card tourist pass. Previously, every single top-up required Korean won in cash. This was the single biggest friction point for arriving tourists, and it is largely gone.
March 18, 2026 — Mobile T-money opened to foreigners on iPhone. The official Mobile T-money app added a dedicated "Foreigners" button on its launch screen that lets you skip Korean identity verification entirely. You add a T-money card to Apple Wallet and top it up with a foreign Mastercard, American Express, or UnionPay card. You can do this from your sofa at home before the flight.
WOWPASS crossed two million users. The all-in-one prepaid tourist card now has kiosks in over 320 locations nationwide and accepts 16 foreign currencies. It has become the default recommendation in a lot of travel forums — though as you will see below, it is not automatically the right choice for everyone.
The one thing that has NOT changed: you still cannot tap your own credit card directly on a subway gate. Seoul's gates read T-money, not Visa. English guides constantly confuse "T-money in Apple Wallet" with "Apple Pay open-loop transit," and they are completely different systems. Seoul is building toward true open-loop payment, but the target is 2030, not now. No T-money, no ride.
Korean Won 101
Korea's currency is the won (₩, code KRW). In mid-2026 it trades around ₩1,450–1,530 to one US dollar, though rates move — check a converter close to your trip.
The useful mental shortcut: knock three zeros off the price and you are roughly at the US dollar figure, minus a bit. ₩10,000 is about $7. ₩30,000 is about $20. Close enough to make decisions without opening an app.
| Denomination | Type | Notes |
|---|---|---|
| ₩50,000 | Banknote (yellow) | Largest note. ATMs dispense these by default. Small vendors may struggle to break one. |
| ₩10,000 | Banknote (green) | The workhorse. Ask the ATM or changer for these if you can. |
| ₩5,000 | Banknote (red) | Handy for street food and market stalls. |
| ₩1,000 | Banknote (blue) | Roughly 70 US cents. Very common. |
| ₩500 / ₩100 | Coins | Coin lockers, vending machines. Keep a few. |
| ₩50 / ₩10 | Coins | Nearly useless. You will accumulate them anyway. |
For context on what things actually cost: a Seoul subway ride is ₩1,550, a convenience store coffee runs about ₩1,500, a bowl of gukbap is ₩9,000–11,000, and a mid-range dinner lands around ₩15,000–25,000 per person.
Your Four Payment Tools, Compared
There are exactly four things that can move money for you in Korea as a tourist. Everything else is noise. Here is how they stack up.
| Tool | Best for | Cost | Main weakness |
|---|---|---|---|
| Foreign Visa / Mastercard | Hotels, restaurants, shops, department stores, online bookings | 0–3% foreign transaction fee, depending on your card | Rejected at some small merchants and self-order kiosks; useless at subway gates |
| T-money card | Subway, buses, taxis, coin lockers, vending machines, convenience stores | ₩2,500–₩4,000 for the card itself, non-refundable | Physical card top-ups at convenience stores still usually need cash |
| WOWPASS | Travelers who want one card for exchange + spending + transit | ₩5,000 card fee + an exchange margin baked into the rate | Rate margin is worse than Myeongdong changers; transit function duplicates T-money |
| Cash (won) | Traditional markets, street food, small eateries, transit top-ups | Exchange spread + ATM fees (₩3,000–5,000 per withdrawal) | Bulky, and roughly 84% of Korean transactions no longer use it |
Which combination should you actually bring?
For most travelers on a one-to-two-week trip, the answer is not "pick one." It is: a no-foreign-fee Visa or Mastercard as your primary, a T-money card for transit, and ₩50,000–₩100,000 in cash as a safety net. That covers every situation you will encounter.
Add WOWPASS only if you fit one of two profiles: you are bringing a meaningful amount of physical foreign cash you need to convert anyway, or your home bank charges punishing foreign transaction fees on every swipe. WOWPASS processes as a domestic Korean card, so it is accepted in the exact places that reject foreign Visas — that is its real superpower, more so than the exchange rate.
Where Your Foreign Card Will Actually Fail
"Accepts cards" in Korea sometimes means "accepts Korean cards." The terminal isn't rejecting Visa — it is rejecting your Visa, because it was issued abroad. This happens maybe 5–10% of the time, and it clusters in predictable places:
- Traditional markets — Gwangjang, Namdaemun, and most local market food stalls are cash-first.
- Street food carts — almost universally cash.
- Self-order kiosks — the touchscreens in fast-food chains and casual restaurants frequently reject foreign cards even when the human cashier's terminal would accept them.
- Small independent restaurants and cafes — particularly older neighborhood spots with legacy terminals.
- Convenience store transit top-ups — the CU or GS25 clerk will almost always say cash only for T-money.
- Korean delivery apps — Baedal Minjok and Coupang Eats require a Korean card and phone number. No workaround for tourists.
- Kakao T — Korea's dominant taxi app does not accept foreign card registration. Use K.ride instead, which was built by Kakao Mobility specifically for foreign visitors and supports English.
Two practical defenses. First, carry two different cards from two different issuers — when one fails, the other often works. Second, tell your bank you are traveling before you leave. Fraud algorithms routinely freeze cards on their first Korean transaction, and sorting that out from a restaurant queue at 9pm is miserable.
Amex and Discover are worth a word: American Express works at major hotels and department stores but fails often enough elsewhere that it cannot be your only card. Discover and Diners Club are rarely accepted at all. Bring Visa or Mastercard.
Currency Exchange: Where to Get the Best Rate
Exchange rates in Korea vary more than most people expect — the spread between the best and worst option is real money on a ₩500,000 exchange.
| Where | Rate quality | When to use it |
|---|---|---|
| Myeongdong / Namdaemun money changers | Best | If you brought physical foreign cash. Look for street-level booths with visible rate boards. |
| Global ATM withdrawal | Very good | The default for most travelers. Rate is near mid-market; you pay a fixed fee instead of a spread. |
| WOWPASS kiosk | Good | Convenient, better than the airport, roughly comparable to a bank branch. |
| Major bank branch (Hana, Shinhan, KB, Woori) | Fair | Reliable fallback, wider range of currencies. |
| Incheon Airport counter | Poor | Only for the ₩50,000–₩100,000 you need on day one. |
| Your bank at home | Worst | Don't. Rates in Korea are meaningfully better. |
Two details that catch people out. Money changers refuse torn or heavily worn notes, so bring clean bills. And exchange booths inside shopping malls consistently give worse rates than the street-level ones a hundred meters away — the convenience premium is not worth it.
ATMs: How to Withdraw Without Bleeding Fees
Not every Korean ATM takes foreign cards. You want one marked "Global ATM" or displaying Visa/Mastercard/Cirrus/PLUS logos. Where to find them:
- Convenience stores — GS25, CU, and 7-Eleven very often have one inside. Available 24 hours.
- Subway stations — the blue "365" ATM booths in most major stations.
- Airports — nearly all accept foreign cards. Use these for your first-day cash.
- Bank branches — Shinhan, KB Kookmin, Hana, Woori. Note these go offline for maintenance around midnight.
Three rules to keep your fees down. Withdraw in large lumps, not small ones — the operator fee is roughly ₩3,000–5,000 per transaction regardless of amount, so four small withdrawals cost four times as much as one big one. Use a 4-digit PIN — Korean ATMs reject longer PINs, so change yours before you fly if it is 5 or 6 digits. And the big one:
⚠ Always choose Korean won — never your home currency. When an ATM or card terminal offers to "helpfully" charge you in USD, EUR, or GBP, that is Dynamic Currency Conversion. The machine picks its own exchange rate, and it is a bad one — typically 3–6% worse than what your own bank would give you. Decline it every single time. Select KRW and let your bank handle the conversion. This one habit will save you more money than every other tip in this guide combined.
Transit Payment: The Part That Used to Be Painful
Transit is where Korea's payment system used to break down completely for visitors, and it is worth understanding your options precisely, because they differ by phone and card brand.
| Your situation | Best transit option | Fee |
|---|---|---|
| iPhone + Mastercard / Amex / UnionPay | Mobile T-money app → "Foreigners" → add to Apple Wallet, top up in-app | 3.7% top-up fee |
| iPhone + Visa only | Physical card at a subway kiosk, or Climate Card at a station kiosk | Kiosk fee varies; Visa is not supported for in-app top-ups |
| Android, any card | Physical T-money card from a convenience store or airport | ₩2,500–₩4,000 card cost, top up with cash |
| Want zero setup | WOWPASS (T-money chip built in) | ₩5,000 card fee |
The Visa gap is the frustrating one and worth stating plainly: as of the March 2026 update, Visa is not supported for in-app Mobile T-money top-ups. If Visa is your only card, buy a physical T-money card or use the new subway kiosks directly — both work fine, they just require you to be standing in Korea rather than setting things up from home.
How much to load? For a three-day Seoul trip with normal sightseeing, ₩30,000–₩40,000 covers it. A full week including a day trip or two runs ₩50,000–₩70,000. Any leftover balance can be refunded at a convenience store, minus a small fee — though the card deposit itself is gone for good.
How Much Cash Should You Actually Carry?
Cash accounts for only about 16% of transactions nationwide, according to Bank of Korea survey data. But that national average understates things for tourists, because the cash-heavy settings — traditional markets, street food, small local restaurants — happen to be exactly the places tourists go.
| Situation | Cash to carry | Why |
|---|---|---|
| Landing day | ₩50,000–₩100,000 | Transit card top-up, first taxi, airport snacks |
| Normal sightseeing day | ₩30,000–₩50,000 in the wallet | Street food, market stalls, the one cafe that rejects your card |
| Market or street food day | ₩50,000–₩80,000 | Gwangjang and Namdaemun vendors are cash-first |
| Card-only itinerary (malls, hotels, chains) | ₩30,000 | Pure backup |
Ask for ₩10,000 notes where you can. The ₩50,000 note is Korea's largest, and a street vendor selling you ₩4,000 of hotteok genuinely may not be able to break it.
Two Money Rules That Surprise Visitors
Don't tip. Seriously.
Tipping is not customary in Korea and is not expected in restaurants, taxis, hotels, or salons. Service charges are already built into the price and staff are paid a fixed wage. Leaving money on the table produces genuine confusion — there are stories of waiters chasing customers down the street to return "forgotten" change. The single exception is international tour guides, particularly on DMZ tours, where ₩10,000–₩20,000 for a full day is appreciated but entirely optional.
Korean payment apps are closed to you
Naver Pay, Kakao Pay, and Toss are everywhere in Korean daily life, and you cannot use any of them. All require a Korean bank account, a Korean phone number, and resident registration. Samsung Pay needs a Korean-issued card. Apple Pay works at roughly 10% of Korean merchants — reliably at CU, GS25, 7-Eleven, Starbucks, Costco Korea, and the big department stores, patchily elsewhere, and essentially never at street stalls. Alipay+ and WeChat Pay have decent QR acceptance if you already use them. For everyone else: contactless Visa or Mastercard plus cash is the answer.
Don't Leave Money on the Table: Tax Refunds
Korea refunds most of its 10% VAT to tourists staying under six months — a net 5–8% back on qualifying purchases of ₩15,000 or more per store, per transaction. At "Tax Free" shops you can often get the deduction on the spot at the register just by showing your passport. Otherwise you keep receipts, get a customs check, and use the refund kiosks at Incheon before checking in. Goods must stay unused and you must leave within three months of purchase.
This is real money if you are shopping seriously — on ₩500,000 of purchases you are looking at ₩25,000–40,000 back. Bring your passport every time you shop.
The Setup That Works: A Simple Checklist
Before you fly:
- Get or confirm a Visa/Mastercard with no foreign transaction fee. Wise, Revolut, Capital One, and Charles Schwab are the names that come up repeatedly for good reason.
- Notify your bank of your travel dates.
- Change your card PIN to 4 digits if it isn't already.
- iPhone + Mastercard? Set up Mobile T-money in Apple Wallet now, from home.
- Bring a second card from a different issuer.
On landing:
- Withdraw ₩100,000–₩150,000 from an airport Global ATM in one transaction. Decline the DCC offer.
- Sort out transit — physical T-money from the convenience store, or a station kiosk.
- Skip the airport exchange counter unless you brought cash you must convert immediately.
Every day after:
- Card first, cash as backup.
- Always choose KRW at the terminal.
- Passport in your bag on shopping days.
That is genuinely the whole system. Korea's financial infrastructure is excellent, fees are transparent, and once you have made these decisions on day one, you can stop thinking about money for the rest of the trip.
Frequently Asked Questions
Can I use my credit card everywhere in Korea?
At roughly 90–95% of the places tourists visit, yes. Visa and Mastercard work at hotels, restaurants, cafes, convenience stores, department stores, and attractions. The exceptions are traditional markets, street food carts, some self-order kiosks, small legacy-terminal restaurants, and subway gates. Carry ₩50,000–₩100,000 in cash to cover those.
Should I exchange money before I leave home or after I arrive in Korea?
After you arrive. Rates in Korea are meaningfully better than what your home bank offers. Best case, withdraw won from a Global ATM once you land. If you are bringing physical foreign cash, exchange a small amount at the airport for day one and take the rest to a Myeongdong or Namdaemun money changer.
Is WOWPASS worth it for a one-week trip?
It depends on your cards. If you already have a no-foreign-fee Visa or Mastercard, WOWPASS is mostly redundant — its transit function just uses T-money anyway, and its exchange rate carries a margin. Where it earns its ₩5,000 is if your home bank charges 2–3% on every swipe, or if you want a card that processes as a Korean domestic card and therefore never gets rejected.
Can I tap my Visa card directly at the subway gate?
No. Seoul's gates read T-money only, whether that is a physical card or T-money loaded into Apple Wallet. Tapping a credit card directly at the gate — true open-loop transit — is not available in 2026. Seoul is working toward it with a 2030 target. Ignore any guide that tells you otherwise.
Why does the card machine ask if I want to pay in my home currency?
That is Dynamic Currency Conversion, and you should always decline it. The terminal sets its own exchange rate, typically 3–6% worse than your bank's. Choose Korean won every time and let your own bank do the conversion.
Can I use Kakao T to call a taxi as a tourist?
Kakao T does not accept foreign card registration. Use K.ride instead — it is built by Kakao Mobility specifically for foreign visitors, takes foreign cards, and supports English, Chinese, and Japanese. Alternatively, hail a taxi on the street and pay by card or cash directly.
What do I do with leftover Korean won at the end of the trip?
You can change notes back at the airport, but you will pay the spread again in both directions. If you have under ₩100,000, most travelers keep it as a souvenir for the next trip or drop it in the charity collection boxes at Incheon. Above roughly ₩500,000, it is worth exchanging back. Coins cannot be exchanged at all — spend them on convenience store snacks before you go.
