How do dowanload applet into MIFARE DESFire EV1 D81

[pitbar]

I have received the MIFARE DESFire EV1 D81 cards, but I don't know how to start. I wonder if i can download an applet on it just like a java card. If yes, which tool should I use? Thanks.

You cannot download an applet on a DESFire card.

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

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

You's better check MIFARE DESFire EV1 architecture first to know how the data is managed on DESFire card.
