Re: Security theatre
"Being within range of another bluetooth device does not mean that you at at all likely to have caught the virus"
I was assuming there could be different levels of alert and/or alerts could be sent to people who were repeatedly within close range, or within close range for more than a certain arbitrary time rather than anyone who had a fleeting connection.
The notification could simply let them know to be alert for the symptoms and offer a test...
Not a solution but another tool in the armoury.
