1. 請問 CR95HF 是否有支援 Mifare Desfire secure mode 的 command API ?
2. 目前在 M24LR-DISCOVERY demo board 無法正確讀取加密過的 UID ，都是 Random，請問有何解決方案?#
The CR95HF chip provide all the necessary setup to access MIFARE Desfire tag but the protocol used to address the secure area is under trademark and thus you have to check with your tag provider or NXP to get this part. Else you can develop your own code to program/ use the CR95HF with your tag. In any case the physical access RF is handled by the CR95HF.Regards
Dear ST team,
does that mean that for any Mifare card (for example, Plus) I can read only it's ID (open) in Sector 0. And for reading other secure secors you will need Authetication procedure with native NXP device?
Or you can write your own algoritm which Authenticate Mifare tag with help of SendRecv(0x04) command?
Dear Uliana,You are right, the CR95HF is able to access to Mifare card and with the help of the send receive command and a good knowledge of the Mifare NXP proprietary protocol you should be able to go further.
