Answer 1

Check junit test for more example

jnasmartcardio

For example I did as follows and manages to detect whether the SMARTCART is connected.

public class Prueba {

public static void main(String[] args) throws Exception
{        
    TerminalFactory context;

    Security.addProvider(new Smartcardio());
    context = TerminalFactory.getInstance("PC/SC", null, Smartcardio.PROVIDER_NAME);

    // Display the list of terminals
    List<CardTerminal> terminals_list = context.terminals().list();

    if (terminals_list.isEmpty())
    {
        System.err.println("No existen dispositivos conectados...");
        return;
    }

    // Use the first terminal
    CardTerminal terminal = terminals_list.get(0);

    if (terminal.isCardPresent())
    {
        System.out.println("La tarjeta electronica esta presente!: "+terminal.getName());
    }
    else
    {
        System.out.println("La tarjeta electronica NO esta presente");
    }
}
}

}
