Just check my library for ACR122u readers. It also supports insert/discard events. It is so simple to use it. Basically you create a class and register two events to that class. Afterwards, call the Watch function. It watches the changes on your device.

//Initializing
NFCReader NFC = new NFCReader();

//Inserted Event 
NFC.CardInserted += new NFCReader.CardEventHandler(...Some function);

//Ejected Event
NFC.CardEjected += new NFCReader.CardEventHandler(... Some function);


//Enabling Event Watching
NFC.Watch();

If any change occurs, it calls the related event. You handle what you want to do there.

public void Card_Inserted()
{
  try
  {
    if (NFC.Connect())
    {
        //Do stuff like NFC.GetCardUID(); ...
    }
    else
    {
        //Give error message about connection...
    }
  }
  catch (Exception ex)
  {
    //Something went wrong
  }
}

public void Card_Ejected()
{
   //Do stuff...
   NFC.Disconnect();
}
