I am finding a kind of java card where the full ATR would be changeable according to my requirement thru some API.
I know this can be done through proxy devices/boards, but it will be much easier to have a card with such capability. Any recommendation or comments?
JavacardOS will not accept order any more, please contact our partner Feitian online Store:

You can ask your card provider for this function.
But i want to know your original intention of this requirement?

Please note that all you can change are the "Historical Bytes". The first (I think) 6 bytes are hardware settings. Trying to change those *will* brick your card.

As @ ThePhoenyx said,
You can only change the historical bytes via a default selected application. There is no way to change the full ATR.
