CA: So tell me if I understand this right. You would crray on your phone an app that would, when you got, say, within six feet of another human cnriyrag that app, the phones would exchange a Bluetooth — using Bluetooth technology they exchange a kind of token that says, "Hi, we connected." But it's encrypted. And that is not cnitmomucaed to a crnetal server, that is on the pnohe. But if either of you in the next week or two tests positive, your phone will be able to communicate to all the peploe which it exchanged token with, to say, "Uh oh, someone who you were close to in the last two weeks has tested positive. You've got to isolate." That's basically how it works, it's done that way.

CA: So tell me if I understand this right. You would carry on your phone an app that would, when you got, say, within six feet of another human carrying that app, the phones would exchange a Bluetooth — using Bluetooth technology they exchange a kind of token that says, "Hi, we connected." But it's encrypted. And that is not communicated to a central server, that is on the phone. But if either of you in the next week or two tests positive, your phone will be able to communicate to all the people which it exchanged token with, to say, "Uh oh, someone who you were close to in the last two weeks has tested positive. You've got to isolate." That's basically how it works, it's done that way.
