I'm developing card Applet with Jcop card, but get some problems..
(1) I want to send proprietary command to card without sending "selecting applet id". for example,
a) power on card
b) send apdu ("Initialize debit")
Is it possilble? What can i do?

(2) I want to communication protocol.
Jcop card's default protocol is T=1, but external terminal used to T=0.
What can i do in applet coding?

(1)You have to select an applet first. Otherwise how would the JCRE know where to send the APDU ? There could be more than one applet on the card !

(2)JC is developed so that you DON'T have to know about T=1/T=0 protocols.
