Korea is close to cashless in cities and stubbornly cash-based at festivals. That gap is where most visitors get stuck, usually at a food stall with a queue behind them.
The short version
Carry 50,000 to 100,000 KRW in cash per person per festival day. Use your card everywhere it works and treat cash as the fallback that actually clears.
Where foreign cards work
Visa and Mastercard are accepted at convenience stores, chain restaurants, department stores, hotels, KTX ticket machines and most city taxis. American Express is accepted far less often. Contactless from a phone works at major chains but fails often enough at small terminals that you should carry the physical card.
Where they do not
Festival food stalls, rural local buses, small-town taxis, temple donation boxes and market vendors. Many of these run on a Korean bank transfer app or a domestic-only card network that your card is not part of. The terminal may physically accept the card and then decline it, which looks like a card problem and is not.
This is why each festival page on this site carries a CARDS line. Read it before you travel out of the city.
Getting cash
Use ATMs marked “Global” or “Foreign Card” at convenience stores and bank branches. Withdrawal limits are usually 300,000 to 1,000,000 KRW per transaction with a fee of 3,000 to 5,000 KRW. Airport ATMs work but airport exchange counters give poor rates.
Withdraw in the city before heading to a rural festival. Small-town ATMs often reject foreign cards outright, and the one machine at the bus terminal is frequently empty by Saturday afternoon.
Transport cards
Buy a T-money card at any convenience store for about 2,500 KRW and top it up with cash. It covers subways, city buses and many taxis nationwide, and it removes the exact-change problem on local buses where drivers cannot break large notes.
You cannot top up T-money with a foreign card at most machines. Load it with cash. For where to buy, how to top up, fare differences and the 2026 foreign-card changes, see T-money and transit cards in Korea.
Practical notes
Keep 1,000 and 5,000 won notes. Festival stalls price things at 3,000 to 8,000 KRW and handing over a 50,000 note repeatedly makes you unpopular and slow.
If a vendor waves you away after the card fails, they are not being rude. They are telling you the terminal is domestic only and they have no way to charge you.
What to do when a card is declined
The order matters, because repeated declines can trigger a fraud hold on the card, which is a far bigger problem than the transaction you were trying to make.
Try once more, then stop. A second attempt catches a genuine read error. A third does not.
Ask whether the terminal takes overseas cards. The phrase is 해외 카드 되나요? (haeoe kadeu doenayo?). A shake of the head is a network answer, not a judgement about you.
Pay cash. This is why you are carrying it.
Check your bank app before assuming the merchant is the problem. Many banks block a first foreign transaction until you confirm it, and Korea is far enough from home that the block is automatic. Telling your bank your travel dates before you fly avoids the whole category.
Note the difference between a card that is declined and a card that is not accepted. A declined card produces an error on the terminal; an unaccepted card produces a vendor waving you off before the tap. The first is your bank, the second is the network.
Korean payment apps, and why they are closed to you
Much of Korea now pays by phone — KakaoPay, Naver Pay, Toss, Samsung Pay — and at a market stall you will often see a QR code taped to the counter instead of a card terminal at all.
These are almost entirely closed to short-term visitors. They require a Korean bank account or a Korean identity verification tied to a Korean mobile number, and there is no tourist route around that. Some now accept foreign cards for online purchases, but the in-person QR payment that vendors use is not available to you.
The practical consequence: a stall with only a QR code and no cash box is a stall you cannot buy from. They exist, they are not common, and cash solves everything else.
How much to bring, and in what form
The rough shape of a festival day, per person:
- Food and drink at stalls: 20,000 to 40,000 KRW
- Local transport, taxis and top-ups: 10,000 to 20,000 KRW
- Entry, where a festival charges at all: usually free, occasionally 5,000 to 15,000 KRW
- Something you did not plan to buy: 10,000 to 30,000 KRW
That is the 50,000 to 100,000 KRW figure at the top of this guide, and it is deliberately generous. The cost of carrying too much cash in Korea is close to zero; the cost of carrying too little in a small town on a Saturday evening is your whole evening.
Get the denominations right. Ask the ATM for an amount that produces 10,000 KRW notes rather than only 50,000s, or break a large note at a convenience store early in the day. Most festival items cost 3,000 to 10,000 KRW, and a stall at peak hour genuinely may not have change for a 50,000.
Exchange versus ATM. Airport exchange counters give poor rates. City exchange booths in Seoul — Myeongdong and Itaewon in particular — give better rates than banks. Foreign-card ATMs are convenient and carry a per-transaction fee, so withdraw in larger amounts less often.
Prices, so the numbers mean something
A rough sense of what things cost makes the cash figure above easier to judge.
- Convenience store coffee or water: 1,000 to 2,500 KRW
- A bowl of noodles or a simple meal in a small restaurant: 8,000 to 12,000 KRW
- A festival stall dish: 3,000 to 15,000 KRW
- A subway ride in Seoul: about 1,550 KRW
- A short city taxi ride: 5,000 to 10,000 KRW
- KTX Seoul to Busan, standard class: roughly 60,000 KRW each way
- A mid-range hotel room outside Seoul: 70,000 to 120,000 KRW
Restaurant prices include tax and there is no tip, so the number on the menu is the number you pay. Side dishes are free and refillable, which is not a promotion.
Tax refunds
Korea runs an immediate tax refund at participating shops for purchases above a threshold, and an airport refund process for larger ones. It applies to shops, not to festival stalls, and it requires your passport at the time of purchase.
If you are buying anything substantial — cosmetics, electronics, clothing — ask about 택스 리펀 (tax refund) before paying rather than after. It is not retrievable once the receipt is printed.
Practical notes, continued
- Keep cash in two places. A day pocket and a bag reserve. Festival crowds are safe by any international standard, but a dropped wallet is a dropped wallet.
- Convenience stores are the universal solvent. They take foreign cards, sell what you forgot, have an ATM, break your notes and top up your T-money. When something goes wrong on a festival day, the nearest CU or GS25 is the answer more often than not.
- Coins accumulate fast and are useless at stalls. Spend them at convenience stores or drop them into the T-money top-up machine.
- Take the remaining cash home or spend it. Korean won is poorly exchanged outside Korea and airport counters at departure give the worst rate of the trip.
Questions worth asking
How much cash should I carry to a festival?
50,000 to 100,000 KRW per person per festival day. Use your card everywhere it works and treat cash as the fallback that actually clears.
Why did my foreign card get declined at a festival stall?
The terminal is likely on a Korean-only network. It can physically accept the card and still decline it, which looks like a card problem and is not one — see each festival's CARDS line for what to expect before you travel.
Can I load a T-money card with a foreign credit card?
Not at most machines. Load T-money with cash — see our T-money and transit cards guide for where to buy and top up.
