NTAG 424 official detection

authways — Tue, 01 Aug 2023 13:29:29 GMT

I'm trying to detect NTAG 424 DNA cards only before proceeding to the main part of my program. What would be the most efficient way to do it?

I'm thinking to call GetVersion Parts1-3 and compare everything is the same as the values mentioned in the NT4H2421Gx documentation, as much as possible.

What is the official way of doing it?

Hello @authways

Thanks for contacting us and choosing the NXP products.

Based on your description, it's recommended that you refer to NTAG 424 DNA and NTAG 424 DNA TagTamper features and hints (nxp.com.cn) which will teach your how to start your development.

That and https://www.nxp.com/docs/en/data-sheet/NT4H2421Gx.pdf has helped me tremendously.
