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.
Japan's domestic interbank clearing network, one of the oldest electronic payment systems in the world, connecting over 1,000 banks and financial institutions. Originally a batch-processing system, Zengin was upgraded to 24/7 real-time operations in 2018 via the "More Time System" extension. Operated by the Japanese Bankers Association with settlement through the BOJ, it handles the vast majority of Japan's domestic credit transfers. Note: data includes all Zengin transactions (both real-time and batch-processed), as the system does not separately report its 24/7 instant component.
