Barcode reader using Device Control on Android wrapped app

Hi, I’m developing a web app that will run in Android devices after wrapping.
I’m now testing it using a tablet with camera: when I have to read barcodes, using the Device Control, the app opens the tablet camera.
When running on a tablet equipped with proper barcode scanner, does anyone know if the app will open it? Or it will use the camera to read barcodes, ignoring the physical barcode reader device?
