South Korea Currency & Money Guide: Exchange, Cards, and Tips

South Korea uses the Korean won (KRW), cards and contactless payments work almost everywhere, tipping is not expected, and you’ll get the best exchange rates by changing major currencies in Seoul rather than at the airport. ATMs are easy to find, but check foreign card fees.

Think of South Korea as a mostly cashless, card-friendly destination where you still want some won for markets, street food, and rural areas. For most trips, exchanging about ₩130,000–₩260,000 (roughly US$100–200) in cash covers incidentals, while the rest can go on card.

You’ll get fair KRW exchange rates from Korean banks, but specialized booths in areas like Myeongdong and Hongdae are usually 1–3% better than airport counters according to several Seoul money guides. Major cards (Visa, Mastercard) and mobile wallets are widely accepted, and ATMs marked “Global” let you withdraw won with foreign cards.

To keep on top of costs, the Hello app can track your trip expenses in multiple currencies (including KRW and SGD) with automatic exchange rate conversion, and split bills with friends even if you’re all paying in different currencies. Combine that with an eSIM from Hello and you land in South Korea already connected and ready to check live rates as you go.

South Korea’s currency is the Korean won (KRW, ₩), and one Singapore dollar (SGD) typically equals around ₩1,000–₩1,050 in recent years, though rates fluctuate daily, so always check a live converter before you exchange. The won operates on a floating exchange rate, not a fixed peg.

You’ll mostly see ₩1,000, ₩5,000, ₩10,000, and ₩50,000 notes, plus coins from ₩10 to ₩500. According to currency guides, 10,000 KRW is roughly US$7.50, making ₩10,000 a useful mental unit for quick price comparisons. Western Union’s Korea currency overview notes that the won has usually traded above 1,000 KRW to 1 USD over the last decades, so don’t be surprised by big numbers on prices — ₩30,000 is only about US$20–25.

For SGD–KRW, recent market data in 2025–2026 often shows SGD in the ₩950–₩1,050 range, but rates can move 5–10% with global conditions, so lock in decisions using a reliable app or bank site rather than an old blog post. When budgeting, many Singapore travellers use a simple rule of thumb: "₩10,000 ≈ S$10" to avoid overthinking small spends.

If you track everything in SGD, the Hello app’s multi‑currency budget tracking and automatic FX conversion can be helpful: you record expenses in KRW, but your trip total stays in SGD (or any base currency you choose). That makes it easier to see if your Seoul coffee habit or Busan seafood dinners are blowing your Singapore budget in real time.

You’ll get the best South Korea exchange rate by bringing major currencies (USD, EUR, JPY, sometimes SGD) and changing them at certified booths in tourist areas like Myeongdong or Hongdae, rather than at airport counters or random street shops. These booths are known to beat bank and airport rates by 1–3%.

The Korea Tourism Organization and Seoul city money guides recommend banks and government‑certified exchange booths for safety and fair pricing. Banks such as KEB Hana, Shinhan, and Woori offer currency exchange during banking hours (typically 09:00–16:00 on weekdays), while certified booths in busy areas stay open later into the evening. Seoul’s official tourism site notes that certified booths display signs with "Certified" and currency symbols, and advises avoiding unlicensed changers.

Popular spots in Seoul include Myeongdong (with multiple high‑rated booths like Money Box and GOGO Currency Exchange) and Hongdae, where several exchange shops cluster near subway exits. According to several 2025–2026 exchange guides, airport counters at Incheon and Gimpo are very convenient but tend to have noticeably worse rates; many locals suggest exchanging just ₩20,000–₩30,000 at the airport for transport, then doing your main exchange in the city.

Elsewhere in Busan, Daegu, and Jeju, you’ll rely more on banks and major department stores, plus ATMs. Always bring your passport when changing money, as South Korean regulations require ID for currency exchange, and amounts over US$10,000 may need a customs declaration at the airport per Seoul city guidance.

South Korea is extremely card and contactless‑friendly, with Visa and Mastercard accepted almost everywhere in cities, but you still need some cash for markets, small eateries, and taxis outside Seoul. ATMs are widely available, though your home bank may charge foreign transaction or withdrawal fees.

According to Seoul’s official money guide, credit cards are widely accepted in shops, cafés, hotels, and even most taxis in the capital, and many terminals support contactless tap payments. Cafés in Seoul or Busan typically accept cards for small amounts like ₩4,500–₩6,000 (US$3–5) coffees, and mid‑range restaurant dinners around ₩15,000–₩25,000 per person can easily go on card. Just check whether your bank adds a 2–3% foreign transaction fee.

ATMs can be found in banks, subway stations, convenience stores (CU, GS25, 7‑Eleven), and department stores. Look for machines labeled "Global ATM" or showing Visa/Plus and Mastercard/Cirrus logos, which accept foreign cards. Some Seoul travel guides recommend withdrawing cash from bank ATMs for better transparency on exchange rates, while convenience store ATMs may charge flat fees of roughly ₩3,000–₩5,000 (US$2–4) per withdrawal depending on your card issuer.

To minimise fees:

• Withdraw larger amounts less often (e.g., ₩100,000–₩200,000 at a time)
• Use ATMs attached to banks rather than random machines
• Decline "dynamic currency conversion" and be charged in KRW, not your home currency

With Hello eSIM for South Korea (South Korea, Hello eSIM for South Korea), you can stay online to check live ATM fee warnings from your bank app or compare exchange rates before tapping "Yes" on any screen.

Tipping in South Korea is not expected, service charges are usually built into prices, and leaving cash tips can even confuse staff, so you can safely follow a no‑tip rule in most situations. Locals rarely tip in restaurants, taxis, or cafés, even in big cities.

South Korean tourism resources emphasise that tipping is not part of local culture: restaurants, hotels, and drivers do not expect extra cash, and many places include a service charge automatically. Even upscale Seoul restaurants typically won’t have a tip line on the credit card machine. If you really want to show appreciation, a small gift or polite thanks in Korean ("감사합니다", gamsahamnida) is more in line with local norms.

In terms of everyday payments, the country is often described as a "card first" society. Domestic apps like Naver Pay, KakaoPay, and Toss are widely used by locals for QR and app‑based payments, but they’re linked to Korean bank accounts and are difficult for short‑term visitors to set up. Tourist‑friendly wallets like Apple Pay or Google Pay work where supported by your bank and local terminals, though plastic Visa/Mastercard remains the most reliable option.

You’ll still want some cash:

• Traditional markets (e.g., Gwangjang Market in Seoul)
• Street food stalls (₩3,000–₩7,000 per item)
• Small guesthouses or countryside cafés

Use cards for larger spends like hotel bills, KTX tickets, and department store shopping, and keep about ₩50,000–₩100,000 in cash for small purchases. If you’re splitting costs with friends, the Hello app’s expense splitting lets each person pay how they like (card, cash, different currency) then settle up later, with automatic exchange rate conversion between KRW and your home currencies.

South Korea is generally safe and honest with money, but travellers should watch for poor exchange rates at unlicensed booths, dynamic currency conversion traps, and occasional overcharging in tourist areas. You can avoid most problems by using certified exchangers, checking receipts, and paying in Korean won.

Local travel blogs and Seoul tourism guides highlight a few common issues:

• Uncertified exchange booths offering attractive signs but hidden fees or bad rates; official sites advise looking for government‑certified signage.
• Dynamic currency conversion (DCC), where card terminals offer to charge you in your home currency at a very poor rate — always choose KRW.
• Tourist area mark‑ups, especially in busy shopping streets, where a simple souvenir can cost 20–30% more than in markets.

Despite these, South Korea consistently ranks as a low‑scam, high‑trust destination compared to many global cities. Basic precautions like keeping cash in a money belt, covering your PIN at ATMs, and checking that restaurant bills match menu prices are usually enough.

Money‑saving tips include:

• Using public transport: Seoul’s subway rides cost around ₩1,400–₩1,600 when using a transport card.
• Eating like locals: simple meals at kimbap shops are often ₩6,000–₩9,000 rather than ₩15,000+ in tourist restaurants.
• Exchanging major currencies at Myeongdong/Hongdae booths instead of airports.

South Korea welcomed over 17 million international visitors in 2023 according to Korea Tourism Organization figures, and many report feeling prices are reasonable compared to other developed countries when using these tricks. To see where your own money goes, the Hello app’s AI receipt scanning and automatic categorisation can show exactly how much you’re spending on transport, food, shopping, and activities in KRW and your home currency.

Most travellers can manage South Korea’s currency and payments easily by remembering three rules: the country uses Korean won, tipping is not expected, and cards work almost everywhere, with cash reserved for markets and small shops. Here are answers to common questions people ask when planning a trip.

Q: What currency does South Korea use?
A: South Korea uses the Korean won (KRW, ₩). Notes usually come in ₩1,000, ₩5,000, ₩10,000, and ₩50,000. Prices can look high, but ₩10,000 is only about US$7.50 or roughly S$10, so don’t be alarmed by the extra zeros.

Q: Should I bring cash or rely on cards?
A: Do both. Many Seoul money guides recommend exchanging around ₩130,000–₩260,000 (US$100–200) for a week for street food, markets, and emergencies, and putting the rest on card. Bigger cities are very card‑friendly; rural or older areas may still be cash‑focused.

Q: Where is the best place to exchange money?
A: Exchange a small amount at the airport (₩20,000–₩30,000) for transport, then do major exchanges at certified booths in Myeongdong or Hongdae, which typically beat airport and bank rates by a few percent according to several 2025–2026 currency exchange guides.

Q: Do people tip in South Korea?
A: No. Tipping is rare and not expected in restaurants, taxis, or hotels, and service charges are usually included. You won’t offend anyone by not tipping.

Q: How can I track my budget easily?
A: Use an app like Hello, which offers multi‑currency tracking, live exchange rates, and AI receipt scanning, so you can log what you spend in KRW but see your totals in SGD, USD, or any base currency while exploring South Korea.
