Singapore's two-layer instant payment infrastructure: FAST (Fast And Secure Transfers, 2014) provides the real-time clearing rail, while PayNow (2017) adds a proxy-based overlay allowing transfers via mobile number, NRIC/FIN, UEN, or VPA. PayNow has cross-border linkages with India's UPI, Thailand's PromptPay, and Malaysia's DuitNow. Governed by the Association of Banks in Singapore (ABS) under MAS oversight, the system supports P2P, P2M, and government disbursements with no transaction fees for individuals.
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.
