Based on Alipay HK figures (announced in 2022), you can pay with Alipay (Alipay / Alipay+ / Alipay HK) at about 120,000 or more merchants across Korea, and the number has kept growing since. From convenience stores like CU and GS25 to Olive Young, Starbucks, Shinsegae Department Store, and Lotte Duty Free, the QR payment you already use works almost exactly the same way. That's why visitors from China, Hong Kong, or Southeast Asia often feel reassured, thinking "everything works here."
But paying in a store and paying for transport (subway, bus, train) run on completely different systems. Alipay works well at retail shops, but tapping the same QR at a fare gate or a bus reader usually doesn't work. Below, let's go through what does and doesn't work with Alipay, and how to handle transport payments with less hassle.
Alipay Works Well at Korean Stores
Alipay+ (Alipay+) is broadly integrated with major merchants in Korea. Based on Alipay HK figures (announced in 2022), you can use it at about 120,000 or more merchants across Korea, and it has kept expanding since, and these are some representative places that accept it.
| Category | Representative merchants (examples) |
|---|---|
| Convenience stores | CU, GS25, emart24 |
| Drugstore & beauty | Olive Young (OLIVE YOUNG) |
| Department stores & duty-free | Shinsegae Department Store, The Hyundai Seoul, Lotte Duty Free |
| Cafés & F&B | Major chains such as Starbucks |
| Fashion & accessories | ABC-Mart and others |
The payment steps are just the same as usual.
- Open the Alipay (or Alipay HK) app and bring up the payment code (Pay) screen.
- For an overseas payment, choose the "Overseas via Alipay+" option, or scan the store's QR.
- Show the code to the cashier or scan the QR to complete the payment.
Note: Exchange rate and fee terms may differ depending on the merchant and payment method. Check the exact billed amount and currency on the app screen right before you pay.
Transport (Subway, Bus, Train) Is a Different Story
This is where a lot of people get confused. "Alipay works in stores, so I can just tap it at the subway gate too, right?" — that usually doesn't work.
Public transport in Korea runs on a transit-card basis, like T-money. Fare gates and bus readers aren't built to tap an Alipay QR directly; they recognize contactless transit cards (or EMV contactless cards) instead.
- Tapping an Alipay QR directly at a subway gate → usually doesn't work
- Using transport requires going through a transit card as an intermediate step
Instead, a few paths for foreigners have been opening up lately.
1) Buying single-journey tickets and the Climate Card with an international card (2026~)
Starting March 17, 2026, at 273 stations on Seoul Subway Lines 1–8 and roughly 440 new kiosks, you can buy and top up single-journey tickets and short-term Climate Card passes (1-, 2-, 3-, 5-, and 7-day passes) with an overseas-issued Visa or Mastercard (per the City of Seoul announcement, with an average 3.7% service fee). However, buying or topping up a regular T-money card is not yet supported for overseas-card payment, so if you need a T-money card, buying one with cash at a convenience store is the sure bet.
Also, you can't top up directly from your Alipay balance at the kiosk; an international credit/debit card is the standard (it varies by card issuer and station).
2) Topping up Apple Wallet T-money with an overseas Mastercard (for iPhone users)
Starting April 9, 2026, iPhone and Apple Watch users can top up their T-money balance in Apple Wallet with an overseas-issued Mastercard. With the topped-up T-money, you just tap your phone at subway, bus, and taxi readers nationwide (Apple Wallet T-money itself has been supported since July 2025). Note that this isn't a method where you tap the Mastercard directly at the gate (open-loop); you first need to add T-money to your Wallet. If you use an iPhone, this route is far smoother than Alipay.
Google Pay had not officially launched in Korea as of 2026. For Android users, a physical transit card or a kiosk top-up is the safe choice.
3) Taxis
Alipay+ is in the process of expanding taxi payment integration, and it's said that some taxis can accept payment via Alipay HK and similar options. That said, support varies by vehicle, driver, and payment terminal. It's a good idea to check the payment method before you get in.
Booking Trains (KTX, Express Bus) Is the Biggest Hurdle
Intercity travel is yet another matter. You can, in fact, book a KTX ticket on KORAIL's official site or the KORAIL Talk app as a non-member using passport information and an overseas card. So the rule of thumb is "KORAIL works too."
The problem is that foreigners often get stuck in practice. These are the typical situations where things stall.
- Failure at the 3D Secure authentication step when paying with an overseas card
- A silent rejection because the name spelling (order or letters) doesn't match the card issuer's records
- A Korean mobile phone number required at some step
- Just a "payment failed" message with no clear error, making it hard to identify the cause
Alipay is not guaranteed as an official payment method for KORAIL bookings, and if the overseas card itself gets blocked, even an Alipay-linked card can be rejected the same way.
Frequently Asked Questions (FAQ)
Q1. Can I ride the subway in Korea with just Alipay? A. Store payments generally work, but tapping an Alipay QR directly at a subway gate usually isn't supported. For transport, going through a transit card like T-money is the standard.
Q2. Is there a way to use transport and trains without a Korean bank account or identity verification? A. A physical transit card can be bought and topped up with cash or an international card, so no separate identity verification is needed. However, online KTX booking often gets blocked at the overseas-card authentication step, so pairing it with a foreigner-only booking app like LACHA, designed so that no separate identity verification is required in its process can greatly reduce your chance of failure.
Q3. Which is more convenient, iPhone or Android? A. As of 2026, the iPhone is relatively convenient because it supports Apple Wallet T-money and, for some Mastercards, direct tapping. Since Google Pay isn't available in Korea yet, for Android we recommend using a physical card or a kiosk.
Q4. What if the fares or supported features differ from this article? A. Payment and transport rules change often. They can vary by card issuer, station, and time, so before you depart, do a final check on the official information from KORAIL, Seoul Metro, and Alipay.
Solving the Gaps Where Alipay Falls Short, All at Once
To sum up, in Korea retail payments are mostly covered by Alipay, but booking KTX and express buses tends to get blocked at the overseas-card authentication wall. That's especially true in the early days after arrival, when you have no Korean bank account, no Korean phone, and no identity verification ready.
LACHA is a foreigner-only transport booking and payment app built for exactly this pain point.
- No identity verification required: Designed so that no separate identity verification is required in its process, without a Korean bank account, phone, or identity verification, so you can start using it the moment you arrive.
- Overseas payment methods supported: You can pay with familiar overseas payment methods like Alipay and WeChat Pay, avoiding the overseas-card authentication problems that got you stuck on KORAIL.
- KTX + express bus combined: You can search and book both KTX and express buses in one app (a first in Korea). No more switching between KORAIL Talk and bus apps to compare.
- Multilingual support: Available in English, Vietnamese, Russian, Thai, Chinese (Traditional), and more.
Use Alipay for store payments, a transit card like T-money for subways and buses, and LACHA for intercity trains and buses. Take on the trickiest part of getting around Korea in the easiest way.
