Thailand’s PromptPay has had a dramatic impact on the national payment landscape, which will continue to expand as Mastercard and National ITMX agree to carry their cooperation forward.
Mastercard and National ITMX (NITMX), Thailand’s key electronic payment infrastructure provider, have extended their long-term partnership to further advance PromptPay — the region’s leading real-time payments platform.
Under a new multi-year agreement, the extended collaboration will focus on enhancing digital payment capabilities and expanding access to simple and reliable payment infrastructure for more Thai consumers and businesses.
Since 2016, the partnership has played a crucial role in supporting Thailand’s shift toward a digital economy, enabling millions to transact quickly, securely, and efficiently. PromptPay is designed simply, so that even elderly and non-tech-savvy people can use it. Therefore, the system is advancing financial inclusion and becoming a trusted everyday payment method nationwide. The average number of digital transactions per user rose fivefold between 2019 and 2023, while cash withdrawals significantly dropped.
Small businesses in Thailand now receive both online and offline payments seamlessly using QR codes. Due to the PromptPay linkage with other countries’ real-time payment systems, Thai merchants can also benefit from low-cost cross-border transfers.
Thailand’s digital payments ecosystem is thriving today, fueled by the rapid growth of PromptPay. As of March 2025, registrations surpassed 81 million, with 2.1 billion transactions totaling over 4.43 trillion baht in a single month — a 13% year-on-year increase.
Built by NITMX and underpinned by Mastercard’s real-time payment (RTP) infrastructure, PromptPay leverages proxy identifiers like phone numbers and Citizen IDs to enable secure, instant transactions. The system supports retail purchases, government disbursements, and peer-to-peer transfers. Among its advanced use cases, there’s real-time fund splitting and automated welfare payments.
Under the new multi-year agreement, Mastercard will collaborate with NITMX to further evolve the platform’s capabilities, ensuring it remains a scalable, high-performance engine for Thailand’s next wave of digital payment innovation.
