Increasingly, people are being asked to quarantine for a couple weeks if they come in contact with someone who has coronavirus. The quarantine is designed to keep you away from others so you don’t spread the virus, and it’s to keep an eye on you just in case you have the virus, too.
It’s the ‘keep and eye on you’ part where the Smartphone comes in.
It’s been reported that in some countries where they are cracking down on sticking to the rules, you better not get caught at Target buying toilet paper or stocking your pantry if you’re supposed to be home quarantining (is that a word?). They are using all the surveillance tools available to trace your steps to make sure you stay home.
