Indonesia's real-time interbank transfer system launched by Bank Indonesia to replace the aging BI-RTGS for retail payments. BI-FAST supports 24/7 instant account-to-account transfers via bank account number or proxy ID across banks, fintech firms, and e-money providers. Built on ISO 20022 messaging with a modern API-based architecture, it is one of two key payment rails in Indonesia alongside QRIS (the QR standard). BI-FAST aims to be the backbone of Indonesia's digital financial infrastructure for its 280M population.
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.
