Korea is an easy country to pay in. Cards work almost everywhere. A transit card covers buses and subways. Still, a little cash is useful. Paying for medical care also has its own points to check.

This guide covers the basics for medical travelers, step by step.

Cards and mobile payments

The Korea Tourism Organization (VISITKOREA) says most businesses in Korea accept credit cards (accessed October 2026). This includes hotels, department stores and general shops. Visa, Mastercard and American Express are widely used. Some places do not take cards, so check before you order.

Card tips, step by step

  1. Tell your bank you are traveling, so your card is not blocked.
  2. Bring two cards from different networks if you can, in case one does not work.
  3. Check your card’s foreign transaction fees (extra fees your bank charges for payments abroad).
  4. Pay in Korean won (KRW). A terminal may offer to charge you in your home currency. This is called dynamic currency conversion. Consumer regulators, such as Australia’s ACCC, warn that paying in your home currency may be the more expensive option (ACCC, accessed October 2026). Your own bank’s conversion is usually clearer.
  5. Expect some websites and apps to refuse your card. Some Korean sites only accept Korean-issued cards. This can affect online bookings and some delivery or taxi apps. Some large apps now accept foreign cards. For example, the taxi app Kakao T accepts overseas Visa, Mastercard, American Express and JCB cards (Kakao Mobility, accessed October 2026).

Mobile payments

Korea has many mobile wallets (apps that pay with your phone). Some international wallets work at some Korean shops. But acceptance varies a lot, especially for wallets linked to non-Korean cards. Do not rely on a phone wallet alone. Carry a physical card too.

Exchanging money

Korea’s currency is the won (₩, KRW). According to VISITKOREA (accessed October 2026):

TypeValues
Banknotes1,000, 5,000, 10,000 and 50,000 won
Coins10, 50, 100 and 500 won

Where to exchange

PlaceGood forNotes
BankLarger amountsGenerally open 9:00–16:00 on weekdays. Hours vary by bank and region (VISITKOREA, accessed October 2026).
Authorized exchange officeLarger amountsVISITKOREA advises using a bank or an authorized exchange service.
Airport exchange counterA small first amountOpen long hours. Convenient on arrival.
Global ATMWithdrawing cash with your own cardSee below.

Many visitors exchange a small amount at the airport and the rest later.

ATMs

ATMs that accept international cards are common. They are marked with a “Global” sign or the logos of the card networks they accept. Many offer English, Chinese and Japanese. You find them at banks and convenience stores, but convenience store ATMs often charge higher fees (Visit Seoul, accessed October 2026). Your own bank may charge a fee too. So it is often better to withdraw a larger amount fewer times.

Prepaid travel cards for foreigners

VISITKOREA lists a foreigner-only, all-in-one prepaid card called WOWPASS. It combines currency exchange, card payment and transit. The card costs KRW 5,000. You can load it with Korean won or foreign cash (such as US dollars, Japanese yen and Chinese yuan) at WOWPASS kiosks. VISITKOREA says there are 430+ kiosks at major airports, subway stations and hotels (VISITKOREA, accessed October 2026). You need your passport. Compare its exchange rate and fees with your own bank card before you load a large amount.

How much cash?

A modest amount for small shops, markets and transit top-ups is usually enough. Avoid carrying large sums. For a large medical bill, a card or a bank transfer to the institution is safer. It also leaves a record.

Bringing a lot of cash? If you bring more than USD 10,000 in total into Korea (all currencies, Korean won and cheques together), you must declare it to customs on arrival. Not declaring it can lead to a fine or prison (Korea Customs Service, accessed October 2026). Your home country may have its own rules for taking cash out, so check them too.

Transit cards

Four steps for using a transit card, with a calendar icon for an unlimited pass. AI-generated image.

Figure 3. How to use a transit card. ① Buy one at a convenience store, station or the airport (around ₩3,000). ② Top it up, usually with cash. ③ Tap it on the subway, buses and many taxis. ④ Refund the remaining balance before you leave. ⑤ Climate Card: unlimited rides in Seoul for 1–7 days.

T-money is the main transit card. Here is how to use it, step by step, based on Tmoney (25 August 2026) and VISITKOREA (accessed October 2026).

Step 1: Buy the card

Step 2: Top it up (add money)

Step 3: Tap and ride

Step 4: Refund the balance before you leave

Climate Card for tourists (Seoul)

The Climate Card is an unlimited-ride pass for buses and subways in Seoul. Prices for the tourist pass, according to Tmoney (as of August 2026):

Pass lengthPrice
1 day₩5,000
2 days₩8,000
3 days₩10,000
5 days₩15,000
7 days₩20,000

The physical card costs ₩3,000 on top of the pass price (VISITKOREA, accessed October 2026). The pass covers Seoul buses and subways only.

Phones

Two official sources talk about different products. A Mastercard press release (9 April 2026) says visitors can use the MobileTmoney app on iPhone or Apple Watch and top it up with a Mastercard card in Apple Wallet. Tmoney’s visitor guide says iPhones cannot issue a mobile card, but that note is about the Climate Card Tourist Pass only, not all mobile T-money services (Mastercard and Tmoney, checked Oct 2026). Check that your phone, the app and your payment card are supported for the product you choose. A physical card is a simple backup. Android users should check the official app store listing before relying on a phone.

After some procedures, you may prefer taxis to crowded subways. See our guide on getting from Incheon Airport to Gangnam.

Paying for medical services

Medical payments are larger than everyday spending. Plan ahead with these steps.

  1. Ask for a written quote before treatment. It should list each item, the currency, and whether tax is included.
  2. Ask about deposits and refunds. A deposit is money paid in advance to book. Ask how much, when, and what happens if you cancel or the plan changes.
  3. Pay the medical institution directly. Use its official card terminal or its business bank account. Be careful if anyone asks you to pay cash to a personal account or to a third party. See our guide on avoiding medical brokers and scams.
  4. Keep all receipts. Ask for a receipt and an itemized bill (jinryobi seboo naeyeokseo, 진료비 세부내역서, a list of every charge). You may need them for insurance claims at home, for tax, or if there is a dispute.
  5. Check your card limit. A large single payment may go over your daily limit. Contact your card issuer before the trip.
  6. Pay in KRW. Letting your bank convert is often clearer than a home-currency conversion at the terminal.

VAT refund change

VAT (value-added tax) is a tax included in the price of goods and services. Korea had a special VAT refund for foreign tourists’ cosmetic procedures. It started in 2016. It was not extended in the 2025 tax reform and ended on 31 December 2025 (Korea.kr, 2025 tax reform). Proposals to bring it back have not been passed (as of October 2026). So procedures from 1 January 2026 are not eligible under that scheme.

Normal tax-free shopping refunds for goods are a separate system. See also our guide on VAT refunds for foreign patients.

Frequently asked questions

Can I use my foreign credit card in Korea? Yes, in most places. VISITKOREA says most businesses accept credit cards, and Visa, Mastercard and American Express are widely used (accessed October 2026). Some small shops and some Korean websites do not.

Where is the best place to exchange money? VISITKOREA advises a bank or an authorized exchange service. Banks are generally open 9:00–16:00 on weekdays. Exchange only a small amount at the airport.

How much does a T-money card cost? Around ₩3,000 for a basic card, with the balance loaded separately (Tmoney, as of August 2026).

Can I top up a transit card with a foreign card? Usually not. T-money top-ups at stores and most machines are paid in cash (T-money, accessed October 2026). From March 2026, the Seoul Climate Card can be bought and topped up with an overseas card at new machines on Lines 1–8, with a fee of about 3.7% (Tmoney, as of August 2026).

Can I still get a VAT refund on cosmetic procedures? No. The scheme ended on 31 December 2025, and proposals to revive it have not been passed (as of October 2026).

Do I need to declare cash when I arrive? Yes, if you bring more than USD 10,000 in total, in any currencies (Korea Customs Service, accessed October 2026).

How should I pay a large medical bill? Pay the institution directly by card or to its business account. Never pay cash to a personal account. Keep the receipt and itemized bill.
