      timeoutMS - the amount of time in milliseconds to enable the reader and wait for a card to be swiped.
      Returns:
      An array of three strings corresponding to the tracks of the card. If a track could not be read that string will be empty.
      Throws:
      ConnectionException - if an I/O error occurs.
