Hello!

Is NTAG424 supported?

User B - 2026-04-27 23:20 UTC

I haven’t tested the feature that pre fills the token in a url but it should be scannable

Hello!

My NTAG424 cards finally arrived, but they seem to have compatibility issues.

Here are some test results:
iOS iPhone SE 2022 + Zaparoo app - write error and read error (but the NFC Tools app reads and writes perfectly).

Windows + PN532 USB - Write error and read error (even if written using a third-party app).

Android + Zaparoo app - Successful reading and writing.
