For javacard, how to log data in the card.
For javacard, how to log data in the card.
I wonder how javacard logs data in the card. Does it need an applet to do this?
Another question is how I can read the log events after transactions. Anyone knows?

Hi,
If a Java Card applet logs data in the card, it's certain that applet's programmer designs the logging mechanism. There is no standardized logging facilities.

See ISOApplet.
The file type ElementaryFileCyclicFixed in this applet also be used to store log data. New log records are preserved, old log records will be overwritten by new log records.
