* Over this session, Application Protocol Data Units may be exchanged with the smart card
* to provide the desired functionality.
* Do not hold open sessions when not using them; they should be short-lived.
* As a security precaution, only one open session is allowed to exist per SmartCardReader;
* subsequent openSession() requests will block until the current session is closed.
