We are working on solution using SAM AV2 for storing and authentication with Mifare Classic cards.
When we try to use SAM_AuthenticateMifare command we always receive error 6985.
We assume that there is a problem with how we store a key.
Could you please help us with instruction how key need to be stored?
Also if there is document that can be useful please provide its name.
If these questions can't be answered in public forum please send us instructions where it can be done.
Our company has valid NDA with NXP and access to docstore.nxp.com
Thank you in advance
