#California announces a public roll out of a contact tracing app that notifies you when your phone has been in proximity to another user/phone who tested positive for #coronavirus .
While people have the choice to opt in by downloading the app, I'm very curious to know what people think of this technology.
Why not write a red P on their foreheads because not everyone has a smart phone to intrude on other people and their health. Merry Christmas anyway Kai,Ford
