Password Protection

[domgamba]

Any consideration for functionality creating password encryption with NFC tags? I have NTAG213 and I need to allow my users to protect their tag so that nobody else can overwrite their content.

Sure you can implement it with the transceive API we provide by using appropriate commands. We actually plan to add more specific support for different types of tags/cards. However it is (obviously) time-consuming and we cannot provide any guarantee about this functionality.

You should refer to the docs of the nfc tag.

@alaashahin1 Please follow this documentation: https://www.nxp.com/docs/en/data-sheet/NTAG213_215_216.pdf
To authenticate a tag, you need to use the PWD_AUTH command (in Section 10.7). This command is what you need to transceive.

@dangfan @jiegec thanks all for consideration.
I read this Section 10.7, but frankly, I don't know what i will do in flutter
