Hi,

Thanks. The example is very helpful.
So, the maximal number of keys for each application is 14. I can assign at most 14 different keys for each application to cardkeyNo (0-13) in the ChangeKey after I select the application?

changeKey(int cardkeyNo , int oldKeyNo, byte oldKeyVersion, int newKeyNumber, byte newKeyVersion, DESFireEV1.KeyType type, byte oldkeydivOption, byte newkeydivOption, byte[] divInput)

Before each access (read, write, ...), a new authentication with the corresponding key is needed, right?
