I am working in a project with the Mifare Desfire chip Ev - 1/2/3 8k , as a card writer/reader, I am using a Proxmarck3 Easy with last Iceman firmware.
I am unsure if it is the best way to write and retrieve data from the card. If you have any better solution, please let me know I will appreciate it.
I can authenticate the card with AMK and CMK, create and delete files and application, but as there is a bug know in the Proxmark firmware (https://github.com/RfidResearchGroup/proxmark3/issues/956), I am not able to change the card keys (Card master key, application master key and all the other keys for the application).
I am kindly asking if there is any solution to this problem.
Which are the best software to use to write and read from a DESFire chips?
Is there any other way to change the keys?
I have ordered an ACR122U too, And it will arrive in a few days, Is there some guidance on how to send commands through it?
Hi Amal, and thanks for the answer.
The MIFARE DESFire EV1 NFC tools can read the card’s data with a given key, but it cannot change any key in the card.
Therefore any application and file that I load in the chip have the standard key. Everyone is able to read delete and modify the data in the implant.
