The Challenge

Restaurants needed order management running directly on Sunmi commercial POS terminals, with thermal printing and reliable background operation.

Our Solution

We built a React Native CLI app with ~2,100 lines of custom Java native modules for the Sunmi SDK, thermal printer control, and an Android foreground service — featuring real-time order polling, AutoTask auto-acceptance, a concurrent action lock, device-based auth, and 3-language support via Contentrain CMS.
