dear @DEOFELIX ,

Hope you are doing great, as you may know the information about 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. 

I saw you submitted an internal case where we can discuss about this device, I will request some information in the case.
