NFC Sign-in Issue with Feitian K40 on iPhone 13 Pro

Feitian K40 with NFC option does not work to sign in on IPhone 13Pro. Tried this on a separate IPhone, doesn't work either. Tried more than 1 key of the same model key, with no luck. I've tried key positioning variations ad infinitum. Thoroughly frustrated.

NFC will usually work, but you need their app setup and you need to be logged in on your iPhone.

Before I posted, I checked the device and this is what Feitien says about which platforms are supported:


  • Works without downloading any drivers. Supported OS: Android, Chrome OS, Windows, MacOS, Linux


It doesn't appear they support iOS.
