In SK the contact tracers also had access to credit card transactions and CCTV to catch any missing cell phone data and to actually even pinpoint contacts. I read an example of one of the cases where it was documented exactly the times of certain purchases and that the infected case had used the bathroom at one establishment in addition to the cell phone data. Those people that received the text notification knew the exact times for these things.That's a good point. The only way to do it perfect is to track cellphones which would be seen as a real invasion of privacy. I was listening to a podcast regarding how it was done in SK. People in the USA would never, ever submit to that.
Essentially there was a girl that tested positive for covid and then her location data was tracked and everyone that had been in the restaurant where she picked up food got alerts that they were close to someone that had covid. I don't remember all the details as it's been a few months, but it was something along those lines. And we know that will never work here.
It is one thing to receive a text message that Infected person A was at starbucks on April 12th. It is completely different to receive notice that person A made a purchase at that starbucks on April 12th at 1:38pm and then used the bathroom at 1:42 pm. If you checked your own receipt and saw your purchase was at 1:39 you are probably rushing to get tested immediately.
These things also help the contact tracers jog people's memories during conversations.
Contact tracer: What did you do Saturday(6 days ago)?
Positive case: Went to home depot and worked around the house.
CT: Oh, ok I see you made a purchase also at the Chipotle next door to home depot.
PC: Oh yeah, I grabbed lunch and ran into a friend there. We talked for several minutes.
