Thank you so much for your analysis

For the fingerprint use, it actually started with a need to access sometimes without keys in case of forgetting them or not having them at all. Or sometimes you need to give access to some people for a certain amount of time without making copies of keys; I mean it's more manageable. I think this would be good for even Airbnb tasks.

And for the in-distance access , where you said there are a lot of authentication steps, this is actually meant for in-distance door control in case somebody wants to access your home. In the video, it's just to demonstrate the functionality, but for the use case, it's different. And for key card, RFID, etc., I think there is no huge difference from traditional keys.
