Our Online Store have the new products: RFID antenna board. Currently it can work with JC10M24R and JCOP4 card chips.
Compared with normal cards, the antenna board module has a smaller size and fixed holes, which is easy to integrate in the IOT(Internet Of Things) project.

Pinpad minimal example

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


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

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