What Is PromptPay and How It Dominates Online Casino Payments?
PromptPay is a real-time money transfer system introduced in 2016 by the Bank of Thailand as part of the government’s National e-Payment initiative. It was developed in collaboration with Vocalink, a Mastercard subsidiary known for building fast payment infrastructures worldwide. The service connects a user’s bank account to identifiers such as a mobile number, national ID, or corporate tax ID, enabling instant payments without needing long account numbers. PromptPay is widely integrated across Thailand’s banking network, covering institutions like Bangkok Bank, Krungthai Bank, Krungsri, Kasikorn Bank, Siam Commercial Bank, TMBThanachart, CIMB Thai, UOB, and others.
By 2025, PromptPay reached over 81 million registered users and was processing more than 2 billion transactions per month, worth over 4 trillion baht. Fees remain low: transfers under 5,000 baht are free, while higher amounts cost between 2 and 10 baht depending on size. For online gambling, this infrastructure delivers speed, reliability, and security, positioning PromptPay as one of the most influential banking tools in the Thai market and a gateway for cross-border play through PromptPay International.
