Great library and example. I will start with these guides. Thank you so much, rena2019.

If that is the case, how can I write data into DESFire card? Is there any samples?

pitbar

You have to implement a proprietary version of CREATE FILE and the ISO versions of READ BINARY and UPDATE BINARY by yourself according to your needs.

FYI: ISO applet viewtopic.php?f=17&t=31 is really a good example for you to learn more on this part.

Hello bro.

Thanks for your help!

But actually I want to monitor some values during the execution flow. What can i do? Is there any method?

pitbar

I think there is no card provider that can allow this.

pitbar

The only way to do this is to delete and reinstall the applet.

pitbar

short lc = (short) (a[ISO7816.OFFSET_LC] & 0xff); It's the standard way to compute Lc byte. short read = apdu.setIncomingAndReceive(); This line is to get at least the beginning of the incoming data in the APDU buffer. while(read < lc) { read += apdu.receiveBytes(read); } Appends whatever addit...

pitbar

cycle call? Why do you want to do this?

pitbar

Firstly, tell us which security domain key you want to send to the card.
