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.
