PromptPay is Thailand’s national real-time payment system enabling instant bank transfers using phone numbers or national IDs. It is widely adopted for both peer-to-peer and merchant payments via QR codes, and has become the default payment rail for digital transactions across the country.

For merchants, PromptPay offers near-universal consumer adoption, instant settlement, and low transaction costs, with no dependency on card infrastructure. Its QR-based checkout is familiar to Thai consumers across all age groups and income segments.
