Physical productfreeThailand

CYD PromptPay Terminal is an open-source DIY hardware project that turns a low-cost ESP32 board with a touchscreen into a payment terminal for Thailand's PromptPay QR payment system. The merchant enters an amount, the device requests a payment through Stripe, displays the resulting QR code for the customer to scan, and confirms once payment succeeds. It requires assembling the hardware and configuring a Stripe account.
