Is it possible to emulate mifare nfc tags like mifare ultralight with nrf52832?

[marco c.]

Hello,

I'am working on a custom project with an nrf52832.
Now I want to use the nrf52 to emulate an nfc tag. Regarding to the technical documentation, the nrf52832 supports type 2 and type 4 tags.

Is it possible to emulate mifare tags like MIFARE Ultralight or MIFARE Ultralight C, that both are type 2 tags or respectively MIFARE DESfire Tage, which are type 4 ?

Using the search function of the forum, i found some previous discussions according to this topic.But have not fully answered my question.

Thanks in advance.

Hi, 

Looking in to your request and will update you. 

From the response in this ticket it seems that at least Ultralight is supported, I am not sure about Ultralight C. 
You can have a look at the discussion here: https://devzone.nordicsemi.com/f/nordic-q-a/28817/nrf52840-desfire-emulation-not-work-with-libfreefare/114132

Hi,

thank you for the additional information. It actually seems that mifare nfc tags can be emulated.

Just adding some extra context:

The hardware does should support emulating the tags but we do not have any SW, so in theory you would have to write your own protocol to achieve this functionality.  And to be clear, the NXP is the owner of Mifare so we don't have any licensing, you can check out a comment here https://devzone.nordicsemi.com/f/nordic-q-a/21038/potential-pitfalls-at-the-iso-dep-layer seems like they this might not be the as straight forward to use their tech, so it is not something we support.

For more specific inquirer about the use of NXP tech i suggest you contact NXP.
