WOWPASS kiosks offer better exchange rates than airport booths, accept 16 foreign currencies, and load a reloadable card usable across Korea. Over 320 machines are installed nationwide — here is how to use them.
Still lining up at an airport currency booth with a fistful of cash? There is a better way. Korea has quietly become one of the most cashless-friendly countries in the world, and the orange kiosks scattered across the country have become a go-to solution for travelers who want competitive exchange rates, a reloadable payment card, and a built-in transit pass — all in one.
Here is everything you need to know about using WOWPASS before and during your Korea trip.
Why WOWPASS Kiosks Beat the Airport Exchange Booth
Airport exchange counters are convenient by location, but their rates consistently rank among the least competitive options available. WOWPASS kiosks, by contrast, are well-documented to offer better exchange rates than most airport booths — and the process takes just a few minutes with no need to speak to anyone.
The kiosks accept a total of 16 foreign currencies, including USD, EUR, GBP, AUD, CAD, SGD, JPY, and PHP, among others. The machine accepts cash in your home currency and loads the equivalent in Korean Won (KRW) directly onto the card. There are no exchange fees charged at the machine — what you deposit is what you get in KRW value.
For travelers arriving with leftover foreign notes from a previous destination, WOWPASS also offers a practical way to put those bills to use rather than hunting for a specialist exchange counter.
Step-by-Step: Your First Exchange at the Kiosk
The process is straightforward even for first-time users.
First, locate a kiosk using the in-app map or the machine locator on the WOWPASS website. Over 320 machines are currently installed across Korea, including at major subway stations, hotels, shopping malls, and airports. Note that machines at Incheon and Gimpo Airports handle card pickup and KRW top-up only — cash exchange in foreign currencies at those specific machines is not available, so aim for a kiosk at a nearby subway station or hotel lobby for your first exchange.
At the machine, select Get a New Card, then choose your currency. Scan your passport when prompted — this is a regulatory requirement for foreign currency exchange. Deposit your cash following the on-screen instructions, and the machine will issue and load the card in one step. Insert the card once to activate it, then register it in the WOWPASS app to unlock balance tracking and card protection features.
One practical tip: feed clean, undamaged notes. Machines can reject worn, torn, or heavily folded bills, so set aside your crispest notes before approaching the kiosk.
App Features Worth Knowing
The WOWPASS app (available in English, Chinese, and Japanese) adds a layer of control that makes the card considerably more useful than a basic prepaid card.
Balance monitoring: Every transaction triggers an instant push notification, and spending history is displayed in both KRW and your home currency — useful for spotting errors or unexpected charges.
Card freeze: If the card is lost or misplaced, the app allows the WOWPASS balance to be suspended immediately, protecting any remaining funds. The card can be reissued at any kiosk for a small fee.
Kiosk locator: The in-app map shows the nearest machines, their operating hours, and which services are available at each location — a small detail that saves significant time if you arrive at a machine that only handles top-ups.
One important note on the transit balance: WOWPASS has two separate wallets — a shopping/payment balance loaded via the kiosk, and a T-money balance for subway and bus travel. These are distinct. The T-money balance must be topped up separately with KRW cash at subway ticket machines or convenience stores. The foreign currency you exchange at the kiosk does not automatically transfer to the transit side.
Where to Find the Kiosks
WOWPASS machines are concentrated in areas with high tourist traffic, but they appear in a wider variety of locations than most visitors expect.
Subway stations: Major stops on Lines 2, 5, and 9 — including Hongik University, Gangnam, Myeongdong, and City Hall — typically have machines either inside the station or within the immediate vicinity.
Hotels: Machines are installed in lobbies at many mid-range and upscale hotels across Seoul, Busan, and Jeju. Notably, these machines are open to non-guests as well.
Shopping malls and entertainment districts: Machines appear near popular retail zones in명동 (Myeongdong), 홍대 (Hongdae), and Dongdaemun — areas where spending tends to be highest.
Airports: Machines at Incheon Terminal 1 and Terminal 2, as well as Gimpo and Jeju airports, handle card issuance and KRW top-up. For foreign currency exchange, use a machine at a subway station or hotel on arrival.
The WOWPASS app's map is the most reliable way to find the nearest machine and confirm what services it offers before making the trip.
Is WOWPASS Right for Your Trip?
WOWPASS suits travelers who want to consolidate currency exchange, cashless payment, and transit access into a single card without relying on international credit cards — which often carry foreign transaction fees and are occasionally declined at smaller merchants and unmanned kiosks.
For those planning to cover significant ground across Seoul — or extend the trip to Busan or Jeju — having a local-equivalent payment card that works wherever domestic debit cards are accepted removes a layer of friction that cash-and-card travelers often encounter.
The card balance remains valid for six years from the last top-up, which means it can be held over for a return visit rather than being discarded at the end of the trip.
