Accept PromptPay in Thailand: A Merchant’s Guide to QR Payments

January 29, 2026

PromptPay has become a central feature of the Thailand’s cashless economy, powering seamless digital payments via bank apps and popular e-wallets.

For merchants serving both local customers and international visitors, accepting PromptPay QR payments is no longer an advantage, but a necessity to stay competitive in the market.

Understanding how to accept PromptPay QR Payments can unlock new revenue streams and position your business for growth in one of Southeast Asia’s most digitally engaged markets.

What is PromptPay?

PromptPay is Thailand’s national real-time payment method, widely used for QR code payments through local bank apps and supported e-wallets. Similar to its regional counterparts such as DuitNow QR (Malaysia), PayNow (Singapore) and QR Ph (Philippines).

For consumers, it offers a fast and familiar way to pay using their mobile devices. For merchants, it has become one of the most trusted and widely adopted digital payment methods in the country, processing over 74 million transactions daily.

How PromptPay QR Payments Work for Merchants

Accepting PromptPay QR payments is simple, fast, and customer-friendly. From a merchant’s perspective, the process is straightforward:

1. Display Your QR Code

   Merchants generate a unique static QR code linked to their account, which can be presented in-store or online.

2. Customer Scans the QR Code

   Shoppers open their preferred bank app or e-wallet and scan the merchant’s QR code.

3. Payment Authorization

   The customer approves the transaction within their app, using familiar security methods such as biometrics, PIN or in-app verification.

4. Instant Confirmation

   Payments are confirmed in real-time, giving merchants immediate relief without the delays with card processing or cash handling.

PromptPay QR works across local bank apps and supported e-wallets, giving customers flexibility while maintaining security and trust.

For merchants, accepting PromptPay is simple with an integration with any supported Payment Service Providers (PSP) like Fiuu.

Why does PromptPay Matter for Businesses and Merchants?

1. The Mobile-first Experience

   PromptPay QR transactions remove the need for customers to carry cash or enter card details manually, creating a fast, secure, and seamless mobile-first payment experience. With online payments in Thailand growing 13.5% year-on-year and card usage declining, customers increasingly prefer instant payments via smartphones. For merchants, this means higher conversion rates and smoother checkout flows.

2. Accept Payments from International Tourists

   PromptPay is connected to 8 payment systems across neighboring regions, including Malaysia, Singapore, Indonesia, Vietnam, and China. Tourists from these countries can pay using their local e-wallets or banking apps by scanning the same merchant QR code, while merchants receive settlement in their own currency. This expands your customer base and opens new revenue opportunities from cross-border spending.
