Does ST25R3920B support MIFARE ?

[zhangxixun]

I am now using your company's ST25R3920B as a digital key reader.

I would like to ask, does the SDK of 3920B support the Philips communication protocol of MIFARE Classic cards?

If so, where can I see it?

THANKS

Hi,

see details in https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/nfc0541-read-mifare-classic-1k/m-p/255197 and other posts related to mifare on this community. 

Also, some devices based on ST25R391x, such as the Flipper Zero, supports Mifare tags. Refer to the Flipper Zero firmware source code for more details.

Hi Brian

 I would like to ask, where can I find the API function interface for reading and writing mifare cards?

Or, which API interface functions should I call to realize data interaction between 3920B and M1 card? Are there any application notes for reference?

Hi,

Such tags use proprietary commands and proprietary authentication/ciphering. As explained in the various posts, the ST25R3920 provides support for the specific framing used by such tags but implementation for the proprietary commands/authentication/ciphering is not provided in the ST25R reference firmware. See the various links in the previous posts for more details.
