Hello sir,
Thank you for your interest in this matter,
Due to the fact that MIFARE is an NXP secure product, we only provide the required support through our tools.
This doesn't mean that you cannot build an application on your own. You could use our Reader Library and create your own implementation based on the available examples from MCUXpresso.
There is also an example of implementation without the use of our library.
I'm sorry but I'm not aware if there is an open-source project.
Best Regards,
Fabian
