FAQ
Which Sunmi and Pax device models do you support for custom POS development?
We develop custom Android POS applications for the entire Sunmi series (V2, V2 Pro, D2, T2, etc.) and Pax smart terminals (like the A920). We utilize the native SDKs for each specific model to ensure flawless performance.
Can you integrate the built-in thermal printer and barcode scanner on my Android terminal?
Absolutely. We build direct communication layers with the device's internal hardware. This guarantees lightning-fast receipt printing, instant barcode scanning, and secure cash drawer triggering without relying on clunky third-party bridging apps.
Will the custom POS software work offline if the store loses internet connection?
Yes. We engineer offline-first Android POS solutions using robust local databases. Your terminal will continue processing transactions locally, and the system will automatically sync the data to your cloud server the moment the internet connection is restored.
Do you also build the web dashboard to manage inventory across multiple POS terminals?
Yes. In our Premium package, we build a scalable central backend (utilizing modern tech stacks like Node.js or Python) and a custom web dashboard. This allows you to manage multi-store inventory, track sales, and update digital menus remotely.
Do I get full ownership and the source code for the POS terminal app?
Yes. Once the deployment is completed and signed off, you receive 100% ownership of the custom codebase and intellectual property. You control your data and your software, with zero ongoing vendor lock-in.
