JavaCard OS

As far as I know, we can set PIN by assigning the value into the code. I wonder whether there is any way to set the PIN code by card user?

If you are refering to the JavaCard variant of smart cards, you can use OwnerPIN's update() method.

From the question you asked, it seems like you are very new to smart card development (especially the JavaCard type). Please familiarize yourself with ISO-7816, ISO-14443, GP-2.1.1, JC-2.X.X and JC-3.X.X standards and APIs (GP - GlobalPlatform standards, JC - JavaCard platform and standard).

It's nice of you to help me. So, I can set any value I want by OwnerPIN's update() method, right?
I have just started smart card development. Anyway, I will do a further study on it as you suggested.

Yes. Read the OwnerPIN API for JavaCard here (http://www.javafind.net/library/111/javacard_specifications-3_0_4-RR/classic/api_classic/index.html?overview-summary.html).

Also, you might want to bookmark the JavaCard API or even download a copy. Bookmark the API (http://www.javafind.net/library/111/javacard_specifications-3_0_4-RR/classic/api_classic/index.html).

I am greatly appreciated for your kind help. Many thanks.
