JavaCard OS

Hi.

I still have some questions about SAM.
If there is someone can make these clear for me, I would be much appreciated.
Q1: What's SAM module always used to do?
Q2: Can the common reader access SAM directly?

SAM module is kind of smart card.
So the main purpose of SAM module is to store secure keys.
And my reader can access SAM directly.

Regarding the connection between reader and SAM, it really depends on the implementation.
