PromptPay
PromptPay is Thailand's national instant payment infrastructure, operated under Bank of Thailand oversight and accessible through every major Thai bank's mobile app. Users link their mobile number or national ID to a bank account and can send or receive money instantly, 24/7, including weekends and holidays. PromptPay has over 60 million registered IDs and processes billions of transactions annually.
For merchants, PromptPay enables real-time payment collection via ThaiQR codes or direct transfer to a registered PromptPay ID. There are no per-transaction fees for person-to-person transfers, and merchant fees through acquirers are among the lowest in Southeast Asia. TransFi generates dynamic PromptPay QR codes at checkout and confirms payment within seconds — critical for tourism businesses, food delivery, and e-commerce where order fulfilment depends on instant fund verification.
