Melvin,
Wanna learn?
Read OCF Programming guide to the fullest and go to any smart card
manufacuter's website... Take it from there.
About your mistake:
Any mistake you make to the card is reversible unless you tend to mess up
with the security and locked your card... then I say bye, bye to your card
Cheers,
Harley

Subject: [OCF] Card ID and Other Inquiries
> Hello guys!
>
> I've done a simple application accessing the card id through the SmartCard
> object. What I've done is just cut and paste some codes to make it work.
> Below is a code snippet which I would like to fully understand.
>
> Code Snippet:
> StringBuffer sb = new StringBuffer("Obtained the following
CardID:\n");
> byte [] atr = cardID.getATR();
> sb.append(HexString.hexify(atr)).append('\n');
> System.out.println(sb.toString());
>
> Output:
> Obtained the following CardID:
> 3B 6F 00 00 80 31 E0 5B 50 48 50 00 00 00 01 3A
> 10 02 00
>
> My questions:
> 1. Obtaining the following output of the code snippet, what do these
numbers
> mean? what do I get when I access the ATR?
> 2. Is there a standard on how to read the said output? I need a unique ID
> for my application and I would like to know where to start parsing these
> numbers.
> 3. How do I write to the card?
> 4. Would my card be rendered useful if in any case I make a mistake in
> writing to the card?
>
> Also, are there any useful sites that would enlighten me regarding the
Smart
> Card file structure and other specifications.

> Thanks.
