How to copy a mifare 8k onto xnt?

My company uses a mifare 8k, it’s a HID DESfire D8L.
Can someone help me how to clone this? Software?
I can read the card on windows with software but i need a little bit more help. Thank you

The xNT is not a DESfire tag. They are not compatible. The xNT cannot be cloned to another card.

The FlexDF is an 8k DESfire tag

But it cannot be cloned either. It is a secure card. But you may be able to get your company to enroll the tag in their system. See the FlexDF section on this page:
