Looking for way to get unique number for java card

Post by Jsine » Thu Sep 29, 2016 11:34 pm

I have lots of java cards. And I want to separate them with a unique number for each card.

My question now is how can I get these number from the cards. Is there any information useful to me?

You can get these information by sending GET Data command( check GlobalPlatform Card Specification for usage of this command).

You can write a simple pair of setSerialNum() and getSerialNum() methods to have you own unique serial number.
