I tried using NFCForms (https://www.nuget.org/packages/NFCForms/) to read RFID tags (MIFARE classic in my case).
I successfully managed to get the intent callback when the app is up&running (and read the serial number), but the app would not launch when it is closed.
I went over all the recommended tips in the forums already:
1) Adding LaunchMode = LaunchMode.SingleTop
2) Adding IntentFilter
3) Adding Tech filter resource
But the app will still not launch.
Can someone please post a working example?
