Does Apple Pay Work in Korea? What a US iPhone Can Do in 2026

What card is in your Apple Wallet? Visa, Mastercard, Amex? That one question decides most of this. Apple Pay with a US card can work in Korea: US travelers report taps going through at shop counters that have a contactless reader, and the subway and bus work once you set up a Tmoney card on your iPhone. The catch is that contactless readers are still the minority, and the transit route doesn't take Visa yet.

At the counter: where tapping works

Korea went big on payment cards long before phones, and most shop terminals still want you to insert a chip. Contactless readers are spreading, but slowly. One 2025 news estimate put them at around 10% of terminals, and Visa's own numbers say only about 15% of foreign Visa card payments in Korea were contactless in the year to March 2025.

So the rule is simple. Look at the terminal before you pull out your phone.

• Usually fine: convenience stores (GS25, CU, 7-Eleven, Emart24), department stores, big chains like McDonald's, and Starbucks. These have taken Apple Pay with Korean cards since 2023, so the readers are there. US travelers report that a US Visa or Mastercard in Apple Wallet usually taps through at counters like these. Amex is hit-and-miss.
• Often not: small restaurants, market stalls, older shops. Many have an insert-only reader, and a few turn away foreign cards altogether.
• Say it: tell the cashier "Apple Pay" before you tap, so they know what's coming.

Why does every Korean guide say "Apple Pay only works with Hyundai Card"? That's about Korean-issued cards. Hyundai Card is still the only Korean card company on Apple Pay. It says nothing about your US card, which runs on the international card networks.

One nice surprise: since June 2, 2026, the food delivery app Baemin takes foreign Visa, Mastercard, JCB and Amex through Apple Pay. One less hurdle if you want dinner brought to your hotel.

On the subway and bus: Tmoney on your iPhone

Your US card can't touch a Seoul subway gate yet. The gates read Korean transit cards, so the trick is to put a Tmoney transit card inside your iPhone and fill it with your US card.

The setup takes about five minutes:

1. Download MobileTmoney from the US App Store. You need an iPhone XS or XR or later on iOS 17.2 or later.
2. On the login screen, tap Foreigner. No Korean phone number, no sign-up.
3. Create the card. It drops into Apple Wallet automatically.
4. Top up in the app with Apple Pay, using a Mastercard, Amex, UnionPay or JCB.
5. At the gate or on the bus, hold the top of your iPhone to the reader. Express Mode is usually on automatically (check Settings > Wallet & Apple Pay > Express Transit Card), so no Face ID and no unlocking. It even works for up to five hours after your battery runs low.

What to know:

• No Visa. The app's top-ups don't list Visa as of October 2026. The foreign-card option opened on March 18, 2026, and Visa may come later. If your Wallet only has Visa, skip to Plan B below.
• Top up in the app, not in Wallet. Topping up inside Apple Wallet still takes a Korean Hyundai Card. US travelers who tried it there got stuck. The fix is always the app.
• Expect a markup. We couldn't find a published rate, but US users report paying roughly 4.5–6% over the base exchange rate, and one reports a small fee per top-up.
• Don't overfill. Leftover balance goes back only to a Korean bank account in your name. Top up 20,000 to 30,000 won at a time, which is a few days of rides for most people, so any per-top-up fee stays small.
• Taxis: a plastic T-money card works in most taxis. Mastercard's launch note mentions taxi rides on the phone too, but Tmoney's own guide lists only subways and buses, so don't count on it. For apps and paying the driver, see our Seoul taxi guide (opens in a new tab).
• No Climate Card. Seoul's unlimited-ride pass can't live in Apple Wallet. If you want it, buy the plastic version.

On Android, Tmoney's KOREA TOUR CARD app does the same job. Mastercard confirms it takes Mastercard top-ups; check the app listing for other cards. Google Wallet doesn't list Korea at all. Taps at shop readers may still go through with a US card, but we couldn't find anyone official saying so, so keep the plastic card handy.

When will a plain tap at the gate work?

Soon, in pieces:

• Jeju: city buses there started taking Visa taps in August 2025, the first in Korea. The island plans a new combined bus reader in January 2027, so carry T-money there as a backup.
• Seoul city buses: planned for 2027. Hana Card, one of the partners, says January.
• Seoul subway: the city's 2025 plan swaps the Line 1–8 gate readers in 2027, but this fall's announcement gave no subway date. The full rollout target is 2030.

Until then, the iPhone route or a plastic T-money card. Which card fits your trip best is in our T-money, WOWPASS and Climate Card guide (opens in a new tab).

Visa only? Your Plan B

Buy a plain T-money card at any convenience store and top it up with won cash at the counter or a station machine. Or get WOWPASS, which is a T-money transit card plus a prepaid shopping card, topped up with cash in 16 currencies at its machines (the WOWPASS app takes Visa only through PayPal). The new ticket machines in Line 1–8 stations also sell single tickets and Climate Card passes on a Visa, with a service fee of about 3.7%. Your Visa still works for shops with an insert slot, which is most of them.

South Korea WOWPASS Prepaid Payment and T money Card

• Who it suits: Visa-only travelers, anyone who'd rather spend from a prepaid balance than run every coffee through a US card.
• Pickup: at a WOWPASS machine. The listing names Incheon Airport Terminal 2 (CU store No. 3, won cash only) and Gimpo Airport, plus machines at Hongik Univ., Myeongdong, Seoul, Gangnam and Dongdaemun History & Culture Park stations.
• Before you buy: all sales are final, and the first registration fee isn't refunded.

My setup, day one

Before you board: data first, so the apps work when you land (will a Korea eSIM work on your phone? (opens in a new tab)). Then MobileTmoney with a Mastercard or Amex and 30,000 won on it. Then a no-fee card for shops, the physical card in your pocket, and 50,000 won in cash. At Incheon, walk straight to the train. Tap the phone. Nap.
