Nfc ring questions

Will the NFC ring act like a normal chip like the xNT? I see it says that it has a supported app or something along those lines, but can I use NFC tools like normal, or another app to use it how I want? It isnt explained well. Thanks!

You’re talking about this?

It’s an NTAG203 which communicates using the standard ISO 14443A commands, so you should be able to treat it just like an flexNT (NTAG216). I’m not certain, but nothing in the datasheet leads me to believe that you can’t write to it with NFC Tools
