Hi,
Hope you are doing well. As you might know, the information regarding DESFire is secured under NDA (Non-Disclosure Agreement), this means that all the information, tools and support should be delivered using secured communication channels and only to customers with active NDA. There are some of the documents and libraries placed in Docstore.
If you don't have NDA or access to Docstore, you will need to contact one of our distributors available in the Distributor Network|NXP to help you through the NDA process, or if you already have an NDA and a contact that help you getting it you will only need to register in Docstore and use that data.
You would need to request the Data Sheet, as this document may help you with more information about the commands.
Best Regards,
Ricardo
