Key Diversification Data

As we all know, the key diversification data is used to derive the session keys. And it is returned by init-update APDU. However, now I have a question. Does it make sense to generate the diversification data randomly for each session using RandomData class?

A strange issue about JavaCard version

I am experiencing a strange issue. For the same APDU command, when I run my applet on Java Card 2.1.1, it returns 0x9000, but returns 0x6D00 on Java Card 2.2.2. As we all know, JavaCard 2.2.2 is compatible with JavaCard2.1.1, so why does this happen?
Hope experts here figure me out.

Are there two chips for dual interface cards?

Does the dual interface cards(e.g. Jcop card, ft A22, ft A40..) have two chips, one chip for contact and one chip for contactless?
