Thai QR
Overview
Thai QR Payment is Thailand's national QR-payment standard, anchored by the PromptPay national instant-payment infrastructure operated by the Bank of Thailand (BOT) + member banks since 2016 [1, 2, [th-cro]]. The Thai QR technical standard is built to EMVCo international security specifications + uses ISO 20022 messaging standards ensuring interoperability domestically + across a growing network of cross-border linkages. By March 2025, PromptPay processes 2.1 billion transactions / over THB 4.43 trillion monthly with nearly 80 million registered users — striking for a 70M-population country (reflecting multi-account registration).
The structural significance: Thai QR is one of Asia's most-developed national QR-payment systems + the global cross-border-QR-mesh pioneer:
- PromptPay × FPS (Hong Kong) — launched December 2023.
- PromptPay × Indonesia QRIS — multilateral interoperability.
- PromptPay × Singapore PayNow — bilateral.
- PromptPay × Malaysia DuitNow — bilateral.
- PromptPay × Cambodia Bakong — bilateral.
- PromptPay × Vietnam VietQR — bilateral.
- PromptPay × Laos LaoQR — bilateral.
- PromptPay × China (Alipay + UnionPay + WeChat Pay) — launched October 30, 2025.
October 30, 2025 cross-border-QR linkage launch with China's three major payment services (Alipay, UnionPay, WeChat Pay) marks major milestone for Thai inbound-tourist payment acceptance. The BOT 2025 draft guidelines propose real-time fraud detection + reporting obligations for payment operators + end-to-end encryption mandate for all electronic transactions.
