McDonald’s installs phone cleaning devices.
The systems operate on the basis of ultraviolet technology.
These systems, powered by ultraviolet technology, destroy up to 99.9% of germs within 30 seconds while customers wash their hands.

How well is that actually going to work? UVC sterilization usually takes much longer than 30 seconds.
WOTA claims 99.9% sterilization via UV-C. Does Japan have false advertising laws? I genuinely don’t see how it can be that fast, but like, it would be dumb to make difficult-to-believe claims if you could be sued for it.
Anyway, mostly unrelated, I used one of these there and I didn’t care if it was that effective. Wasn’t gonna be holding my phone for that span, so any sterilization is nice.
It’s dose dependent not just time dependent. LED uv-c emitters can pump a huge dose onto a surface from a short distance such as this device does.
This recent study showed viral inactivation using such shorter time frames.
