Apple Pay has launched in Korea, allowing iPhone and Apple Watch users to use the country’s transit system, Tmoney, without feeling overshadowed by Samsung’s mobile payment services. Users can purchase and recharge Tmoney cards directly within the Wallet app, and can enable “Express Mode” by tapping an iPhone or Apple Watch on a Tmoney machine. The automatic recharge function can be adjusted or canceled anytime via the Wallet or Tmoney app, and remains active even when switching to a new iPhone. The service does not support postpaid payment options like traditional Tmoney cards, credit cards, or Samsung Pay. However, users can enable “Express Mode” by tapping an iPhone or Apple Watch on a Tmoney machine without opening an app or waking the device. The service has built-in security functions to protect personal information and does not collect or track user data or transit history. However, restrictions apply, such as not supporting local government fare subsidy cards and balance top-ups using credit cards within the Apple Pay Wallet. Apple Pay Tmoney is available only on devices running iOS 17.2 or later
