JavaCard OS

eJava Token is an excellent java card product. Thanks for this.
Now I want to change ATR of eJava Token. Is there any method to change ATR of eJava Token? Thanks a lot.

The ATR of eJava Token can be customized during production. But after you received the token, it's impossible to change ATR value by yourself.

So if you want the specified ATR value, please let us know in advance once you placed the order.

Sorry for any inconvenience caused.
