check the failed authentication counter

I got some java cards. However, I know nothing about these cards but the card model. Is there any method to check the failed authentication counter? And how can I know if the cards are already blocked due to too much failed tries?

How to "logout" from my card?

I have uploaded and installed an applet into javacard successfully. And I can select applet and send APDU command to my applet. But now I want to deselect the applet. I mean I want to "logout" from my card. How can I do this?
