NFC Reader for ST25DV04KC

Hi,

I'm working with the ST25DV04KC tag (ISO15693 type 5) and I want to both read and write data to it.

I'm looking for a compatible NFC reader that can connect to the computer via USB port, using an USB-to-Serial converter. 

The use case would be to write an application in Python that can use this reader to read/write data to the above mentioned NFC tag in NDEF format.

Maybe someone can help me with the following questions:

1 - Can anyone recommend a NFC reader that can communicate with NFC type 5 tags?

2 - Can anyone recommend a Python library for communicating with NFC type 5 tags? I've found a library called nfcpy, but the documentation suggests that it only works with tags of type 1, 2, 3 and 4.

Thanks!

    Hi Vinicardinali,

    STEVAL-ST25R3916B is supported by ST25R3916-DISCO GUI (STSW-ST25R010). This GUI contains also a DLL with some small projects (C#,C++,python) to perform basic NFC operations. It also contains the ST25PC-NFC which can read/write NDEF from ST25T/DV tags.  The ST25PC-NFC uses ST25 SDK which you can also check out.

    Not 100% fit to what you are looking for but all functionality you want exists somehow.

      Hi Ulysses,

       

      Thanks! Can you tell me where I can find this DLL that you're talking about? I would like to take a look at the projects that you're mentioning (especially in Python). I am able to install the software.

      I am trying to find a Python library that can work with the STEVAL-ST25R3916B board. I tried using nfcpy in Windows, but it doesn't seem to find it.

      Thanks!

      Hi,

      as said the Python example (no library) comes with ST25R3916-DISCO GUI (STSW-ST25R010).

      Hi,

      Thanks for the suggestion. I was doing some research and I ended up in the same board as you mentioned.

      I think this evalboard is the best option for me now. I know also that some reader from FEIG can be used, but again, the DISCO board is more suitable for me.

      Best regards,

      Vinicius
