#3so I'm guessing something like Time-based One-Time Password algorithm (TOTP) then flashed out from flashlight to the sensor on the door?
Why not just TOTP in my google Authenticator app then just type into keypad?

This new technology works in all types of weather. HAVR, reacts not with sunlight as such but with the bright transmission of the flash (on-off tones/signals), a little bit as a unique morse code.

#5My first reaction is that the pattern would be readable by other devices nearby (including skimmers designed for that purpose). I guess that wouldn't matter if there was an underlying sequence-changing algorithm known only to both devices, a la spread-spectrum frequency hopping.

I understand that it's not opened by a lot of light, but with some pattern in the light intensity.
My question is how reliable it is in a sunny day when there is a lot of background light and the signal to noise is much smaller. Do you have a working prototype?
