TL;DR
Short trip (under a week)? Get T-money at any convenience store for β©2,500. It handles subway, buses, and that's enough. Staying two weeks or longer? WOWPASS is the move: transit plus Visa-card payments in one, loaded from your foreign currency at a kiosk. Cashbee? Skip it. It works, but nobody will miss it.
What Each Card Does
T-money is the transit classic. Tap on the subway, tap on the bus, tap at a convenience store register. That's about it. No restaurants, no cafes, no shops beyond GS25 and CU. It's been around forever and every Korean person has one buried in their phone case.
WOWPASS showed up a few years ago and solved a real problem. It's a prepaid Visa card with T-money transit built in. You feed foreign cash (USD, EUR, JPY, whatever) into a kiosk machine, it spits out KRW onto your card, and now you can pay at restaurants, cafes, and shops, anywhere Visa works. Plus transit.
Cashbee is the third option nobody asks about. Transit card, some shop coverage, slightly less recognized than T-money. It works fine. But if T-money is available (it always is), there's no reason to pick Cashbee instead.

Where to Buy at Incheon
Terminal 1: CU convenience store near the AREX Express Train gate. Open 06:00β22:50. WOWPASS kiosk machines are right there too. You can exchange currency and load the card before you even get on the train to Seoul.
Terminal 2: Same setup. CU near the AREX gate, same hours. WOWPASS machines available.
All three cards are sold at both terminals. T-money and Cashbee are also at every subway station vending machine in Seoul, so there's no rush if you miss the airport.
Tip
Arriving late? Download the WOWPASS app beforehand and pre-order through KKday or Klook. You get a pickup code and grab the card whenever you want. No line, no timing pressure.
Why WOWPASS Matters for Foreigners
Here's the thing about Korea that catches people off guard: it's one of the most cashless countries on earth, but your foreign credit card won't work at half the places you try it.
Small restaurants? Cash or Korean card only. Street food vendors? Cash. That cute cafe in Ikseon-dong? Maybe your Visa works, maybe it doesn't. Apple Pay technically launched in March 2023 through Hyundai Card, but you need a Korean bank account and a Hyundai Card to set it up. So for most foreigners, Apple Pay is useless here.
Korean payment apps like KakaoPay and Naver Pay require λ³ΈμΈμΈμ¦ (identity verification), tied to a Korean phone number and resident registration. As a tourist or short-term visitor, you're locked out.
WOWPASS fills that gap. It's a Visa card that doesn't need a Korean bank account, doesn't need λ³ΈμΈμΈμ¦, and works at the same places Korean cards work. It's not perfect (the dual-wallet thing is annoying; more on that below), but it's the closest thing to "just pay normally" that foreigners get in Korea right now.
For a deeper look at the bank account and phone number puzzle, the ARC, Phone, and Bank Account Guide covers the full catch-22.
FAQ
-
What's the dual wallet thing? WOWPASS has two separate balances: a "shopping wallet" and a "transit wallet." Money you exchange at a kiosk goes into shopping. To ride the subway, you need to transfer some into the transit wallet through the app. It takes 30 seconds but it's an extra step that trips people up on day one.
-
Can I use both WOWPASS and T-money? Yes. Some people carry T-money for transit (since it's lighter and they already have one) and WOWPASS for everything else. Redundant, but it works.
-
How do I get my money back when I leave? WOWPASS: insert the card into any WOWPASS kiosk, enter the code from the app, withdraw in KRW cash. β©1,000 fee per withdrawal, max β©100,000 per transaction. The β©6,000 card cost is non-refundable.
T-money: walk into any CU or GS25, ask for a balance refund. β©500 fee. Max β©20,000 at convenience stores; higher balances need a subway station service center.
- Does WOWPASS work outside Seoul? Yes. Anywhere that accepts Visa. Busan, Jeju, Daegu: it all works. The kiosk machines for reloading are mostly at airports and major tourist spots though, so load enough before heading to smaller cities.
Korea's payment setup is built for Koreans. That's not a complaint, it just means you need one workaround, and WOWPASS is the best one available right now.
And the official WOWPASS site has current exchange rates and machine locations.
