Barcode Decoder App Symbol Scan & Decode Examples

The symbols below may be used to test the scanning of the Barcode Data Decoder App & Xamarin SDK to demonstrate functionality. With default settings, the symbols on this page should scan and produce the result shown. If the symbols do not scan on your device, completely shut down the app, make sure you provide camera access permissions to the app, and then restart the app.
