Smart Barcode Reader

About this app

Turn your Android device into a fast, reliable, and highly customizable QR and barcode scanner that integrates seamlessly with your own backend systems. Perfect for business, events, logistics, and more.

This app captures QR codes and barcodes instantly and sends the scanned data to a configurable HTTP server of your choice. The server processes the data - using any logic you want - and returns a response that the app immediately displays.

Because you define the backend, the app becomes a flexible scanner component for any workflow or enterprise system.

The app sends each scanned code as a JSON message:

{
"data": "...",
"userName": "...",
"password": "Hash value of the configured password"
}


Your server needs to respond with:

{
"result": "..."
}

The value of "result" must be the received data (i.e., the value of "data") in order to confirm successful data processing or an error message the app will show to the user.

If a connection test is performed from the settings page, the app sends an empty string as the value of "data". In this case, an empty string must be returned to confirm that the login credentials are correct.

This simple protocol allows you to integrate:

- SQL databases
- ERP systems
- Warehouse management systems
- CRM platforms
- Ticketing systems
- Your own Python, Node.js, Go, or Java backend

You have full control over processing, validation, and response messages.
