+## Using a physical Scanner
+You can use any generic USB, wireless or 2.4Ghz 1D/2D barcode scanner. These act like a keyboard.
+Hence you can use them on any device that has a browser and keyboard support. Most Android phones and tablets have support for physical keyboards.
+If you have a wired scanner, you can buy an OTC adapter (micro USB / USB C to USB A) to connect your scanner via USB.
+For wireless scanners you have to connect via Bluetooth.
+
+It's also recommended to disable virtual / physical keyboard on the Android device:
