This might be a cool gimmick to have at high end luxury hotels eg.) the Conrad, Ritz, four seasons that when your room key RFID is tapped instead of having to manually open your door it opens for you.

I personally see it as a Luxury Gimmick but im sure there are other more essential markets for it

Make sure you get some kind of Patent as the patent is where the value will be

Thank you very much for the note; yes the patent process is step one. I built a timeline graphic that's in the linked site.

I was also thinking like industrial or medical applications, so that doors would be hands free. As a home device, I'd like to make a really simple version - think The Clapper for lights [1] - that could help elderly or mobility impaired people in their own homes. I've had a great introduction with a Patent Attorney who will assist crafting a broad, useful patent application, which is exiting in its own right!
