Hi Martin

My library is an alternative to libnfc + ifdnfc on Linux that will
hopefully work with more adapters.

Thanks for the suggestion.

Absolutely. I use the "standard" Linux NFC subsystem that appeared in
2011:

https://lore.kernel.org/linux-wireless/1307051170-17374-1-git-send-email-lauro.venancio@openbossa.org/

Even though one might be tempted to consider this the single true Linux
NFC subsystem, it does not seem to be used much. There is neard
https://github.com/linux-nfc/neard
and, more recently, libfido2
https://github.com/Yubico/libfido2

libnfc of nfc-tools and ifdnfc are older and do not use the "recent"
interface on Linux. The tools support other platforms, too.

Then there is of course Android, probably the most common use of NFC
+Linux in practice, with yet another approach...

Best,
