Request/Response/Notification Model
When the Smart Card Application receives a Request, it initiates the requested action. If the
action completes in a timely manner, a Response message is sent informing the Host Application
of completion. If the request does not complete in a timely manner, a Response message is sent
indicating that the command has not yet completed (Response Code 80 (Hex)) and that a
Notification message will be sent later when the command has completed. The Notification
message is identical in every way except for its Command Type to the Response message that
would have been sent if the request had completed in a timely manner.
