I think this is a very interesting move. Watching the video, it looks a bit like NFC tap to beam (which most android devices use) or bump (now shut down) except with the OS level integration. I'm not really sure how good doing it at an OS level is. It could create a real barrier to adoption - you can't just download it from Google Play.
