I have a contactless card reader and contactless smart card that has this installed https://github.com/tsenger/CCU2F https://github.com/tsenger/CCU2F It works in mobile Chrome just fine with built in NFC, but it doesn't work in Windows and Linux last I tried, because there's no support for U2F NFC in desktop browsers yet. Surely there's a way to meet in the middle somewhere, so instead of doing it in software it would use a smart card via card reader.
