if the ST25R3916 is compatible with NXP's tag/reader?

Hello

I am gonna use ST25R3916 for NFC in our products, but I am wondering that if the ST25R3916 is compatible with NXP's tag/reader? I remember that NXP's tag/reader has it's own encryption for communication... so I worry that ST25R3916 can't communicate with NXP's tag/reader.....

thanks;

Hi Andrew,

In the ST25R* reference software software ST does not implement any cryptography.

ST knows that cryptography schemes like TripleDES/Desfire or Crypto1 (needed for Mifare (TM) ) can be implemented on top of the ST25R chips. So these tags are supported but you will need to implement the cryptography on your own.

​Hello,

ST25R3916 and ST25R3911B supports different tag technologies and standards as featured in the datasheet. The ICs do support the required frames to be sent and received, but we do not provide and support software for NXP's encryption schemes.

BR, Carlo

Hello Carlo:

Thanks for your answer;

Here are some more questions:

1): as we know, in the read/write process of NXP's MIFARE tag such as MF1S50YYX_V1, it need for authentication for start, I noticed that in the datasheet of ST25R3916 it says"Low level modes to implement MIFARE® Classic compliant or other custom protocols(page1)",

does it means that ST25R3916 can communicate smoothly with NXP's MIFARE tag such as MF1S50YYX_V1?

2): does ST25R3916 support most popular NFC reader/tag in the world? or does ST25R3916 can communicate smoothly with most popular NFC reader/tag in the world? such as NXP's, TI's, or other brand's?
