Paying in Korea: Cards, Cash and WOWPASS for Visitors
How foreign visitors pay in Korea: when foreign cards work, how WOWPASS and T-money fit in, and where cash is still useful.
Last checked
South Korea runs on cards. Restaurants, cafes, taxis, convenience stores, and shopping malls all take them, and many places have gone fully cashless. For a foreign visitor, the question is not whether cards work, but which card to use, and where cash is still needed.
Foreign credit and debit cards
Visa and Mastercard issued abroad work at most major retailers, hotels, and restaurants. Some older terminals and smaller shops may decline foreign cards, and a few domestic-only payment systems will not accept them at all. It is normal for a card to work at a department store and fail at a neighborhood eatery.
Two practical notes. First, carry a backup card from a different network. Second, check with the card issuer about foreign transaction fees before the trip, because they vary widely.
WOWPASS: the foreigner prepaid card
WOWPASS is a prepaid card made for foreign visitors. According to the official site, it combines currency exchange, general card payment, and a transport card function, with the balance managed through a mobile app.
Cards are issued at self-service kiosks. The official site lists kiosks at hotels and stations, and says major subway stations always have kiosks available. Cash can be loaded in 16 currencies, and the app can pause a lost card to protect the balance.
WOWPASS works where regular Korean cards are accepted, which helps at smaller merchants that decline foreign cards. The transport card balance can be checked and topped up in the app. For refund terms on any unused balance, see the official site before you travel.
T-money: still worth having
T-money is the transit card system for Seoul and most of the country. It is sold and topped up at convenience stores and vending machines in airports and subway stations. Anyone taking buses or the subway needs a transit card of some kind.
WOWPASS includes a transport card function, so a traveler using WOWPASS may not need a separate card. Travelers who prefer to keep transit and spending separate can buy a standalone T-money card.
Where cash is still needed
Despite the cashless trend, cash is still useful in specific places: street food stalls, traditional markets like Gwangjang and Namdaemun, some small restaurants, and temple stays or rural guesthouses. A modest amount of won covers these.
ATMs at banks and convenience stores dispense won to foreign cards, though fees apply. Exchange rates at airport counters and downtown exchange shops differ, so compare the posted rates before you exchange.
Quick comparison
| Option | Best for | Keep in mind |
|---|---|---|
| Foreign credit or debit card | Hotels, department stores, large restaurants | Some small shops decline it; check foreign transaction fees |
| WOWPASS | Daily spending and transit in one card | See official site for kiosk locations and refund terms |
| T-money card | Buses and subway | Top up at convenience stores and machines |
| Cash (won) | Markets, street food, small guesthouses | ATM fees apply |
A simple setup for the trip
One workable combination: a WOWPASS card for daily spending and transit, a foreign credit card as backup for hotels and large purchases, and a small amount of cash for markets and street food. That covers most payment situations a visitor will meet.
Rates change daily; check the live rate. Exchange rates and card terms shift, so confirm current details in the WOWPASS app or with the card issuer before traveling.
