As a newcomer in Java Card world, I need some information about the Example "TicketingExampleCards".

InnerCard.java imports the package "com.nokia.phone.sdk.concept.srv.modules.nfc.cards.SecureCard" and it is included in emulator.jar. I couldn't find any javadoc about it.

Is extended SecureCard a Framework?
I see some differences to a Java Card Applet, if I look at the source codes in tutorials.

Please, welcome to explain.
