HChange security level 0 on mifare plus with APDU command

mygodess — Sun, 25 Aug 2024 23:32:10 GMT

We are using nxp mifare plus in mass production.

When we want to use it as mifare classic, the secutiry level should be changed NXP said.

There is a tool named RFID Discover to change the mifare security level 0 data but it is not designed for mass production.

I used it for pre production but I need to change the security block in mass production.

Is there the way to change it with APDU commands?

Hello @mygodess

Yes, RFID Discover can do what you want, but it's not suitable for mass production. However, the design resource you want are the security documents, and you need to sign an NDA with NXP to have access.

so please establish an NDA with NXP by going to https://www.nxp.com/support/support:SUPPORTHOME and select "Request an NDA"

Ok, if you have an NDA, then you need to send email support.docstore@nxp.com to request access to these documents.

I got the Card Test Framework and trying to change mifare Security Level. I still have some problem to write Perso. There is the example to do similar one with Desfire but it does not help that much to do with Mifare Plus. Is there some example for Mifare plus? Maybe there is tome problem to authenticate.
