Hong Kong's Faster Payment System enables 24/7 real-time transfers in both HKD and RMB between banks and stored-value facilities. Uniquely dual-currency by design, it supports proxy-based addressing via mobile number, email, or FPS ID. Operated by HKMA with settlement through the CHATS RTGS system, it has become the backbone of Hong Kong's digital payment ecosystem with 12M+ registrations.
Mexico's Sistema de Pagos Electrónicos Interbancarios is one of the world's earliest 24/7 real-time payment systems, operated directly by the central bank (Banxico). SPEI processes both high-value and retail payments with no maximum transaction limit, settling in real time through Banxico's accounts. It supports CLABE (standardised 18-digit account numbers) and has been extended with CoDi, a QR-based overlay for merchant payments. Note: SPEI data includes both immediate and scheduled transfers on the same rail, as Banxico does not separately report real-time vs deferred transactions.
