I have successfully uploaded and installed an applet into my A40CR card.
But I don't want anybody to remove my applet or add other applets on the card.

Many thanks.

I have some IFD A40CR cards and a R502 smart card reader.
Just now I have been told that there are two kinds of APDU, short APDU and extended APDU.

I also know that my cards support short APDU. But can I send extended APDU to my javacard ?
Do I need a tool to send extended APDU ?

The card shown on the STORE page is colorized, but I received white cards. Are these cards IFD A40CR ?

Do those cards have the same features as you introduce on the product page ?
Thank you for your answer.
