WOWPASS Explained: Is It Worth Getting?

By Dragon Kim · Updated October 23, 2026 · 7 min read

What is WOWPASS and what does it do?

WOWPASS is a card you load by feeding foreign cash into a machine, and you then spend the won balance wherever offline card payments are accepted. The WOWPASS service guide lists 16 currencies, including USD, EUR, AUD, CAD, GBP, SGD and PHP, and describes card payment anywhere cards are accepted in Korea.

• Exchange: WOWPASS lists currency exchange as free of charge, and says machine rates can beat airport rates, so compare in the app. A third-party blog says the spread can be roughly 2 to 5 percent below the mid-market rate, which is its own estimate, not an official figure.
• Payment: The chip works for in-person payments across Korea, including some places that do not take international cards, according to WOWPASS.
• Transit: The card includes a T-money function. Our T-money card guide covers the basics of that system.
• Extras: The app can send money to other WOWPASS users and to Korean bank accounts for a 500 won fee, and sells items such as eSIMs and passes.

How much does WOWPASS cost?

The listed price is a one-time 5,000 won registration fee, with a 4,500 won price when you reserve through the app, and most other actions are free. The fees below come from WOWPASS pages read on October 23, 2026, and WOWPASS says app-reservation discounts apply only sometimes.

A third-party blog reports about a 4 percent fee when you top up by credit card or PayPal and an issuance price near 6,000 won. Those figures differ from the WOWPASS pages, so treat them as unverified and check the price shown on the machine or in the app.

How do I get and load a WOWPASS?

Buy it from a WOWPASS machine, which the operator places at Incheon Terminal 1 and 2 stations, Gimpo Airport Station and downtown subway stations, and bring your passport. WOWPASS names Seoul Station, Hongik Univ. Station and Myeongdong Station as city locations, and a third-party guide says there are roughly 400 machines nationwide.

1. Choose the machine. At Incheon, WOWPASS says AREX Express riders buy a ticket, pass the express gate and use the machine there; others buy a single ticket to the city and use a machine nearby.
2. Issue the card. Select a new card, scan your passport and, if you reserved online, enter the voucher code. A third-party guide says the minimum first top-up is 5,000 won.
3. Load won. Feed in cash in a supported currency. WOWPASS says cash top-up at machines is free. Some machines also take foreign credit or debit cards, and the app takes selected overseas cards and wallets.
4. Load T-money separately. Add cash at subway kiosks or convenience stores, or use the app on an iPhone 7 or later or a Samsung Galaxy with NFC on. WOWPASS says T-money cannot top up the card in the other direction.
5. Tap and pay. Use the chip at shops, and tap the T-money side at subway gates, buses and taxis.

Practical example: a visitor flying in with 300 US dollars in cash can exchange part at the airport machine, keep the rest in dollars for a later downtown top-up, and load 20,000 won of T-money for the first days. Our Incheon Airport to Seoul guide compares the airport routes where you would use that card.

Where does WOWPASS work, and where does it not?

It works for chip payments at offline shops, plus subways, buses, taxis and convenience stores through T-money, but it does not work online or in apps. WOWPASS says the IC chip works anywhere in Korea and that the card cannot be used for online or easy-payment methods.

• Cash-only vendors: WOWPASS suggests its send-to-bank-account feature, for a 500 won fee, when a stall takes only cash. Our Gwangjang Market guide shows what market food costs.
• Not accepted: Delivery apps and online checkout. A third-party guide adds that it does not pay for KTX bookings, so see our KTX booking guide.
• Small shops: The same guide says some small vendors may not accept it, so keep a little cash.

How do I get my money back?

Withdraw the remaining won as cash at a city WOWPASS machine, 100,000 won at a time for a 1,000 won fee, or keep the balance for your next trip. WOWPASS says you need its app, a registered card, the 8-digit code on the machine screen and PIN verification, and that machines in the Incheon Airport AREX area do not offer withdrawal.

• T-money leftovers: WOWPASS lists a 500 won refund fee. Under 20,000 won goes to GS25 or 7-Eleven, under 30,000 won to CU or Emart24, under 50,000 won to subway information centers, and larger amounts to Tmoney Town at Seoul Station. Our T-money card guide has the details.
• Keeping it: WOWPASS lists the card and balance as valid for six years, counted from issuance and from the last top-up or reissue.
• Lost card: WOWPASS says the T-money balance cannot be recovered on re-issue, so avoid loading large T-money amounts.

Is WOWPASS worth it compared with T-money and cash?

It is worth it if you carry foreign cash and want one card for exchange, shops and transit; if you already have a travel debit card and just need transit, a plain T-money card is simpler. The table compares the three options on points WOWPASS and VisitKorea state.

The T-money card price comes from the VisitKorea transportation cards page, and the full comparison with other passes is in our Seoul transit passes comparison. If your bank card already works, skip WOWPASS unless you value exchange at a machine.
