Pinpad minimal example

Post by jw202 » Tue Sep 08, 2020 7:25 am

Hello,

I'm a little bit confused with the ISO-Standards. I would like to write an applet, which has to be unlocked by a PIN. For entering the PIN, I would like to use a cardreader with PIN-Pad.

However, I do not know the exact APDU such that the PIN reader asks the user for the PIN. In my previous applets I use some random bytes for CLA and INS. This clearly does not work with a PIN reader.

Can someone give me a minimal code example?


Kind regards
JW

PS.: I also need a PIN pad reader for linux (just for using javacard, not programming). Is there a pre-purchase-recommandation?
