Covid 19 contact tracing AP

How do these tracing APs function?   I downloaded the CARE19 Ap to see how it works since I will be doing contact tracing with the Dept of Health.   It seems to rarely pick up where I am (maybe because I don't have functions like bluetooth enabled on my phone?).   But it concerned me when I made a purchase at a food truck with my credit card and I automatically got a receipt in my email and I did not give them my email.

You receiving an email with your receipt has nothing to do with the CARE19 app.  These days some merchants are using smart terminals that can "read" the email address info coded into the card or, possibly, stored in the cloud.  If you've ever used a phone app or your computer to access your credit card info the company will have an email address associated with it.

As for the CARE19 app, if you don't have Bluetooth and probably Location both enabled it's not going to be able to do anything.  The app operates by sensing other phones using Bluetooth and, of course, it has to have Location Services running to know where this contact was made.  If your phone "learns" that you were near the phone of a person who later discovered they have the virus then you will be notified.
