Re: unique identifier for smartcards
When you issue the card you should set the IIN (issuer identification number) and CIN (card image number) in the card manager. You can then get these to uniquely identify a card. Try it.

My code doesn't work with RSA key
I am working on a java card project. But now I have difficulty to continue. I can't do RSA key with a length different than 512 bit. As my codes show, I try to throw a CryptoException. but it doesn't show any error message. Could anybody tell me where I made the mistake in my code? Thanks very much ...

Change SCP of J3D081
I have seen J3D081 in the e-shop. Does this card support SCP01? Can I change SCP01/02/03 by myself ?

Re: How can I reduce memory consumption?
Two tips for you:
- If possible, allocate all applet resources in the constructor.
- Use a big buffer instead of several small buffers

Would you tried again?

Re: JCOP Tools
As far as I know, JCOP is not free. Why don't you try to use JCIDE? In my opinion, it's much more powerful for java card development.
And it is FREE. I think it's much better for us.
