Thailand's national e-payment system, a core part of the government's National e-Payment Master Plan. PromptPay links bank accounts to mobile numbers or national citizen IDs for instant P2P transfers, and includes a standardised QR code system for merchant payments. Operated by NITMX under Bank of Thailand oversight, it connects all major banks with zero fees for transfers under THB 5,000. PromptPay has cross-border QR linkages with Singapore's PayNow, Malaysia's DuitNow, and other ASEAN systems.
Japan's domestic interbank clearing network, one of the oldest electronic payment systems in the world, connecting over 1,000 banks. Originally batch-only; upgraded to 24/7 real-time in 2018 via the More Time System. Underpins consumer real-time transfers in every Japanese bank's mobile app, any-bank ATM transfers, and the bank-funding legs of major consumer wallets (PayPay, LINE Pay, Rakuten Pay, au PAY). Operated by the Japanese Bankers Association with settlement through the BOJ. Note: data includes all Zengin transactions (real-time and batch-processed).
