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.


Symbol 1. GS1 QR Code with two FNC1 and MOD10 verification, ending in GS, RS, and EOT. The MOD 10 check digit required for AI (01) will show up in green if the calculation is correct.
