WOWPASS vs T-money vs Cashbee: Which Card to Get at Incheon Airport (2026)

LocalNomad Team··8 min read

You just landed at Incheon Airport. You need a way to get into Seoul. Three cards are calling to you from the convenience store counter. So which one actually makes sense?

Here's the honest take: if you're only here for a few days and want zero hassle, get T-money. If you're staying longer or want one card for everything, WOWPASS wins. Cashbee? It's the forgettable middle child—works fine but doesn't stand out.

Let me break down what you actually need to know.

What Each Card Actually Does

WOWPASS: The Swiss Army Knife

WOWPASS is an all-in-one prepaid debit card that combines:

The magic: You load your home currency directly into the card at a kiosk machine. No currency exchange booths, no haggling over rates.

Card Cost: ₩5,000 (~$4 USD, one-time) Currency Loading Fee: 0% (included in the exchange rate) Reload Fee: Free (at machines or app) Monthly Fee: None

T-money: The Transit Classic

The OG Korean transport card. Works everywhere for:

Card Cost: ₩2,500–₩3,000 basic / ₩4,000–₩5,000 for designer cards (K-Pass, Kakao Friends) Reload Fee: None (just cash top-up at convenience stores or subway stations) Monthly Fee: None Extra Perks: Small 2–5% discount on transit fares if you load ₩10,000+

Cashbee: The Forgotten Middle Child

Similar to T-money but with slightly better shop coverage:

Card Cost: ₩2,500–₩4,000 Reload Fee: None Monthly Fee: None

Honest assessment: Cashbee works, but it's less common. Many stores recognize T-money first. Unless you have a specific reason, skip it.

Where to Buy at Incheon Airport

Terminal 1

Terminal 2

💡

Pro tip: If you're arriving at an odd hour, download the WOWPASS app and pre-order online through KKday, Klook, or Trip.com. You get a pickup code and can grab it whenever. Saves waiting in line at the airport.

⚠️

Important: WOWPASS has a hidden quirk—there are separate "shopping balance" and "transit balance" wallets. Money you exchange at a kiosk goes into shopping. You still need to load the transit wallet separately for subway/bus use. Read the app before your first use.

Transit Coverage: Which One Works Where?

All three cards work on:

The Difference:

💡

Taxi note: When paying by card in a taxi, you may need to tap the machine to confirm. Always verify the driver accepts card payment before getting in—most do, but older taxi drivers sometimes prefer cash.

Payment Coverage Outside Seoul

If you're road-tripping to Busan, Jeju, Daegu, etc.:

If you're staying outside Seoul for more than a few days, WOWPASS's payment coverage makes life significantly easier. T-money means you're using your credit card for anything beyond transit + convenience stores.

Refund Process When Leaving Korea

WOWPASS

  1. Find a WOWPASS exchange machine (airports, major subway stations, tourist information centers)
  2. Download the WOWPASS app and register your card
  3. Insert your card into the machine
  4. The machine displays an 8-digit code—enter it into the app
  5. Withdraw balance in KRW cash
  6. Fee: ₩1,000 per withdrawal (₩100,000 max per transaction)
  7. Timeline: Instant

What's Left Behind: The ₩5,000 card cost (non-refundable)

T-money

  1. Go to a convenience store (CU, Ministop, Emart24) or subway station ticket booth
  2. Tell them you want to refund your balance
  3. Staff will process it on the spot
  4. Cash refund (minus ₩500 service fee)
  5. Maximum: ₩20,000 at convenience stores; higher balances at subway station service centers
  6. Timeline: Instant

What's Left Behind: The card cost + ₩500 service fee (non-refundable)

Cashbee

Same as T-money—refund at convenience stores or subway booths, instant, minus the card cost and fees.

💡

Pro tip: If you have more than ₩20,000 on your T-money card when leaving, visit a subway station service center instead of a convenience store. Or just spend it before you leave—seriously, a ₩15K coffee and pastry are worth not having to deal with a refund. The LocalNomad Community regularly reports on which convenience stores have the friendliest staff for refunds.

Which One Should You Actually Get?

Get T-money if:

Get Cashbee if:

The Real Talk

For Most First-Time Visitors (3–7 days): T-money. It's ₩2,500, works for transit, and you'll have a credit card for restaurants anyway.

For Digital Nomads & Longer Stays (2+ weeks): WOWPASS. The ₩5,000 upfront cost pays for itself in convenience. No hunting for ATMs, no currency exchange headaches, and you can use it at restaurants without a second card.

For Everyone: Download Naver Map or Kakao Map before you leave the airport. You'll use these more than your transport card.
