How about EC signatures?
My Yubikey (which I imagine is a bit more sophisticated than a NFC tag can be) is said to be able to hold Ed2519 keys and use them for signing, but I was never able to actually do that. :)

I'm using a GPG key on my Yubikey, and while I haven't tried using Ed25519 and Curve25519 in particular (GPG support for these is still not ubiquitous), the GPG smartcard application in general works quite well for both SSH and actual OpenPGP use.
