What we build

Android POS Development: what we build

POS apps for Android terminals, tablets and handheld devices. Here are the six kinds of Android POS development work we are asked for most often.

Hardware integration

POS hardware we integrate on Android

Most Android POS problems are hardware problems. We test with your actual devices, because each manufacturer's SDK behaves differently.

Hardware Usual connection What we handle
Receipt printers Built-in, USB, Bluetooth or network Layouts, logos, languages and paper-out errors
Kitchen printers Network Routing items to the right station
Barcode scanners Built-in, USB or Bluetooth Fast scanning and unknown-code handling
Card terminals Integrated SDK or connected device Starting checkout and receiving the result
Customer displays Second screen Order summary and messages for customers
Weighing scales USB or serial Weight-based items
Kitchen display screens Network Live orders and status updates
NFC readers Built-in Cards, tags and loyalty identification

Straight answers

Is Android POS Development right for you?

We would rather recommend less than sell you more. Here is how we judge it.

A good fit when

  • You use or plan to use Android POS terminals
  • Hardware integration is critical
  • Staff take orders on handhelds
  • You need offline operation

  • Your outlets use Windows or iPad POS

    We can build for those, but this page is about Android.

  • A standard POS app supports your hardware

    Configuring it may be enough.

  • Hardware is not yet chosen

    Choose devices first; the SDK shapes the app.

FAQ

Android POS Development FAQ

Why use Android for POS?

Android POS terminals combine a touchscreen, printer, scanner and card reader in one device, come in many sizes, and let businesses run custom apps. Android is now one of the most common platforms for modern POS hardware.

Can you integrate our receipt printer and scanner?

Yes. We integrate receipt and kitchen printers, barcode scanners, scales and customer displays through the manufacturers' SDKs or standard protocols such as ESC/POS, and test with your actual devices.

Can an Android POS app connect to card terminals?

Yes. We integrate with card terminals through their SDKs or connected-device protocols, so the POS starts checkout and receives the result automatically.

Does an Android POS app work offline?

Yes. Orders and sales are stored on the device and synced to the back office when the connection returns.

How are POS apps updated across many devices?

We distribute apps through Android Enterprise or a mobile device management tool, so updates roll out to all terminals in a controlled way.

Which Android POS devices do you support?

We work with common all-in-one Android POS terminals, tablets and handhelds. Because each manufacturer's SDK differs, we confirm and test your chosen devices early. [VERIFY device brands you want listed]
