Hong Kong's Faster Payment System (FPS) is integrated with Thailand's PromptPay. Launched on December 4, 2023, the FPS x PromptPay Link enables cross-border, real-time QR code payments for travelers between the two locations.
Hong Kong residents can use supported mobile banking apps or e-wallets (such as HSBC, BOCHK, Bank of East Asia, and Octopus) to scan PromptPay QR codes at over 8 million merchants in Thailand.
The service is designed for retail merchant payments, not for transferring funds to personal accounts in Thailand so this only works if your landlord is a company with a QR code for payment.
