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.
The first modern US instant payment system, operated by The Clearing House (owned by 22 of the largest US banks). RTP launched in 2017 and supports credit transfers up to $1M with immediate finality — no chargebacks or returns. It also offers Request for Payment (RfP) messaging for bill pay and invoicing. While FedNow provides Fed-backed infrastructure, RTP has a head start with broader bank connectivity and higher transaction limits, and processes the majority of US instant payment volume today.
