How javacards Logs data in the card?

Question

I want to know how transactions will be logged in a java card? did it performed by applets? and after transactions, how I can read log events? did the card supplier put a function in the .dll files to read log or something?

thanks

If a Java Card applet logs events, it does this in exactly the way that it's programmer designed the logging mechanism. Logging/transaction history/etc. is usually something application-specific, thus, there is no standardized logging facilities.
