How to launch my app via NFC tag?

Question

I\'m currently working on porting an app to UWP. The app has a page with a \"Write to NFC\" button. After the user taps it, it waits for an NFC tag and writes a Launch

Answer 1

Here is a way :

1. Register a background task and using a NFC trigger
2. Register your app for uri activation.

3. Program the backgroundtask to activate when tapped with a NFC tag and then launch the app suing URI schemes

   // Set the recommended app

   var options = new Windows.System.LauncherOptions();
   options.PreferredApplicationPackageFamilyName= "Contoso.URIApp_8wknc82po1e";
   options.PreferredApplicationDisplayName = "Contoso URI Ap";
   
   // Launch the URI and pass in the recommended app 
   // in case the user has no apps installed to handle the URI
   var success = await Windows.System.Launcher.LaunchUriAsync(uriContoso, options);
