QR payment covers the entire island's bus fleet

Since August 2024, every one of Jeju's 868 buses accepts fare payment through QR codes generated by supported overseas mobile payment apps. The list covers 14 apps issued across nine countries, including Alipay for travelers from China, along with apps used in the Philippines, Thailand, Malaysia, Singapore, and other markets. This isn't a pilot program on a handful of routes — it applies fleet-wide, which means you don't need to check in advance whether your specific bus number supports it.

The system runs on Korea's Zero Pay platform

Technically, the QR option is built on Korea's domestic Zero Pay platform, which is why it can interoperate with apps issued by foreign payment providers rather than requiring a Korean-issued card. Using it carries a transaction fee of about 0.9%, a detail worth knowing if you're comparing it to a T-money card, which doesn't carry a per-ride percentage fee in the same way.

How to pay by QR at boarding

The general mechanism for QR bus payment follows the pattern common to QR transit payments elsewhere: open your supported app, generate or display its payment QR code, and present it to the reader at boarding.

This guide doesn't detail the exact on-screen steps for every supported app, since that specifics weren't confirmed in the research behind this article — if your app has its own transit-payment mode distinct from a general payment QR code, check that app's own instructions before you rely on it for your first ride.

If your app isn't on the supported list

Not every mobile payment app is part of Jeju's QR system, and if yours isn't, you have two straightforward fallbacks that both remain fully standard on Jeju buses: a T-money transport card, which you can buy and reload at major convenience stores and which also works on buses, subways, and taxis across Korea, or exact cash, which is accepted but must cover the full fare upfront since cash payments don't carry a transfer discount. Neither fallback requires any advance setup beyond finding a convenience store for a T-money card, so a QR-unsupported app doesn't leave you without options.
