Hi,

I have some difficulties to understand what is the IID of a MiFARE card. I have understood that it is a unique number, but i can not understand if the IID is confidential for each card.

Is a IID confidential ?

If yes, how can retrieve it ?

If no, where can i get precise information about IID in general ?

Thanks for your future answers,

Gwendal Cournée

Hello,

Thank you for your answer. I have already read the document you mentionned, and some cases cover multiple type of MiFARE Cards. I have read all documents for MiFARE Plus cards, so I guess I will keep looking in these.

Regards,

Gwendal

Hello,

By any chance, does this application note that talks about the MIFARE Type Identification Procedure help you? 

As you might know, there are some of the documents and libraries which are under NDA (Non-Disclosure Agreement) and placed in Docstore,  most of the information regarding the MIFARE PLUS is there; could you please follow this guides?

Also, you will need to contact one of our distributors available in the Distributor Network|NXP  to help you through the NDA process.
