Stop reader

[glints]

Is there a way to stop the reader from listening? If I use reader.close(), the entire node.js process stops (on mac). reader.disconnect() doesn't work either. Reader keeps listening.

reader.on('card.off', card => {

            try {

              reader.emit('end');


          	} catch (err) {
          		console.error('error when reading data', err);
          	}
});

reader.on('end', () => {

          reader.close();
});

I basically want to have an interface with a button 'read NFC' and on click it needs to listen for nfc input, but once the card leaves and input is read, I want the nfc process killed. Help would be much appreciated.

Got it, just changed the on. to once. so the event happens only once. Fairly new to node.js here...
