How to access Pinpad of a Smartcard Reader when developing a Javacard Applet

QUESTION

How to access Pinpad of a Smartcard Reader when developing a Javacard Applet

Asked 2021-Nov-12 at 10:47

I am relatively new to Javacard and I am in the process of developing my own Javacard Applet which works quite well until now. I am also writing a host program to communicate with my card (via APDUs), this program is written in Java and uses the javax.smartcardio library as well as apdu4j.

My goal now is to use my reader's integrated Pinpad to ask the user for a PIN and then forward the entered PIN to the Smartcard which will verify the PIN. I already wrote the code on the card which will verify the PIN (CLA: 0x80, INS: 0x04, P1: 0x00, P2: 0x00, pin data), but I have no idea how to tell the Reader to probe for a PIN and then forward this information to the Card.

My Card is a J3H145 by NXP (Javacard 3.0.4 / ISO7816 / ISO14443) and my Reader is a ReinerSCT cyberJack RFID standard.

Thank you in advance.
