Hi all:



I have a question about Sample APDU Script of HelloWorld
into the Java Card Development Kit PDF file
(Chapter 11, page 66).


In the Applet Component the AID of the applet is
A0:00:00:00:62:03:01:0C:01:01


but when I have seen that in create APDU, the AID is
A0:00:00:00:62:03:01:03:01


Why is different? Is a mistake in the document?


Thanks in advance

Hi Carlos,


the first AID is the applet AID. The second one is the applet instance AID. Remember, you may want to have several instances of the same applet running on the card, so the applet AID is not enough. As you can see in the script, the applet instance AID is used to select an applet once it has been created.


Cheers,


Julien
