- WOWPASS can help with payment, exchange, and transportation for travelers.
- Some Korean mobile payment apps may require Korean identity verification.
- Carrying a small amount of cash is still useful.

Which payment method should you use?
Subway and bus
Use T-money or the transportation balance on a compatible visitor card such as WOWPASS.
Convenience stores
Foreign credit cards often work, but keep cash or another card as backup.
Restaurants and cafes
Use a foreign credit card at most mainstream places. Small local restaurants may vary.
Traditional markets
Carry cash. Some vendors may accept cards, but cash is still useful.
Taxis
Many taxis accept cards or T-money, but keep a backup payment method for unusual cases.
Online reservations
Foreign cards may fail if the site requires Korean verification or a domestic payment flow.
Currency exchange
Use airport counters, bank ATMs, or visitor services such as WOWPASS depending on convenience and fees.
Common payment problems in Korea
Foreign card not accepted
The merchant terminal, card network, issuer settings or shop policy may block the transaction. Try another card or cash.
Card works offline but not online
Some Korean online services require local authentication, Korean phone verification or domestic payment flows.
Mobile payment requires Korean verification
Kakao Pay, Naver Pay and similar apps may require Korean identity, phone or bank account setup for full use.
Transportation card balance is separate
T-money balance and prepaid payment balance may be separate, especially on multi-function visitor cards.
Some small shops prefer cash
Markets, stalls and very small local businesses may be easier with cash.
Taxi card payment may vary
Most taxis are card-friendly, but terminal issues, card type and route conditions can still create friction.
Mobile payment options
- Apple Pay / Google Pay - Works at some stores if your card supports it, but not universally.
- Kakao Pay / Naver Pay - Korea's dominant mobile wallets. Full features may require a Korean bank account, phone number, or identity verification.
- Samsung Pay - Popular locally; foreign cards may work on compatible Samsung phones depending on card and device setup.
Watch out
Do not assume every shop takes foreign cards. Look for Visa or Mastercard stickers, or ask "Card okay?" before ordering.
Getting cash
- Use Global ATMs at CU, GS25, 7-Eleven, or inside subway stations.
- Airport ATMs work but may have longer queues.
- Withdraw larger amounts less often to minimize international ATM fees.
- Exchange counters at the airport are convenient but rates are slightly worse than bank ATMs.
Tipping & splitting bills
Tipping is not expected or customary in Korea. Service charges are rarely added. Splitting bills is common, and many restaurants accept separate card payments. Say "ttaro gyesanhae juseyo" to ask to pay separately.
Where WOWPASS can help
WOWPASS can help travelers who want a prepaid card, currency exchange, a transportation card function and a practical option without a Korean bank account.
When T-money is enough
T-money is enough when you mainly need subway, bus and many taxi payments. It is not a general payment card for all shopping, restaurants or online reservations.
For long-term residents
If you are staying more than a few months, opening a Korean bank account makes life significantly easier. You will need your ARC (Alien Registration Card), passport, and sometimes proof of address. Shinhan, KB, and Woori Bank have English services.
