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.
Saudi Arabia's instant payment system launched by the Saudi Central Bank (SAMA) as part of the Vision 2030 digital transformation agenda. sarie (meaning "fast" in Arabic) enables 24/7 real-time transfers between banks and fintech providers via IBAN or mobile number, with settlement in seconds. Built on ISO 20022 messaging, it supports P2P, P2M, and bulk payments. The system is a key enabler of Saudi Arabia's goal to increase non-cash transactions to 70% by 2030.
