Vietnam's 24/7 instant interbank transfer system operated by the National Payment Corporation of Vietnam (NAPAS) under State Bank of Vietnam oversight. NAPAS 247 connects all major domestic banks for real-time transfers via account number, card number, or phone number. The system has been a cornerstone of Vietnam's rapid cashless payment adoption, with the government targeting 80% of adults with bank accounts by 2025. It also supports QR payments through VietQR, an interoperable QR standard similar to Thailand's PromptPay QR.
Unified Payments Interface is a real-time interbank payment system built on top of IMPS infrastructure, enabling instant mobile payments via QR code, phone number, Aadhaar, or virtual payment address (VPA). With 300+ participating banks and 50+ third-party apps (Google Pay, PhonePe, Paytm), UPI processes 14B+ transactions per month and has become India's dominant payment method for both P2P and merchant payments. Now expanding internationally with cross-border linkages to Singapore's PayNow and other ASEAN systems.
