This is a creepy "slippery slope" towards an Orwellian society where "big Brother" knows your every move. I find this very creepy.
This is not even a slipperly slope...this is right off the f**king cliff! This has absolutely nothing to do with preventing epidemics and is just an effort to overcome people's expectations of privacy when it comes to having their every movement recorded and preserved to serve whatever purpose government or big business can conjure up to help them stay in control of the masses.
Even as this is just a plan, for now, the worst scenerio that is coming out of this is exploring the issue of psychological resistance to the use of personal information thereby creating a negative mark on people who don't want their information shared with the government. Automatically if you choose not to share your information, you are labeled a subversive. This can't be good at all, and reminds me of the beginnings of a previous New Order.
