WOWPASS — All-in-One Prepaid Card for Foreigners
Summary
An all-in-one prepaid card for foreign visitors: exchange ~16–20 foreign currencies into Korean won at 240+ kiosks and pay on Korea's domestic network — accepted at places that sometimes reject overseas Visa/Mastercard, with no foreign-transaction fee. It also holds a separate T-money balance for subway and buses.
How to use
Reserve online or issue a card at any WOWPASS kiosk (passport needed), then top up by inserting cash/foreign currency at the kiosk. The shopping balance and the T-money transit balance are separate — load T-money with KRW (or move funds via the app on iPhone) before riding transit.
Conditions for foreign visitors
Conditional discount notes
WOWPASS is a payment/exchange tool, not a discount. Brand reward offers are conditional and change; exchange rates and limits apply (e.g. up to ₩2,000,000 top-up per day).
