If I walk a mile along a busy city street, I'm probably better off not knowing how many times I'm on camera. Banks have them, of course. Police cars are just some cars with dash cams. There might be a random motorcyclist with a GoPro. Other businesses undoubtedly have cameras. Traffic cameras are there for traffic, but I'm sure we've all been seen on one just crossing the street. For his benefit, I did hear the QR codes at menus are starting to revert back to physical menus...part of the reason being is that people want an excuse to look at something beside their phone. Then again, we probably all have those shopper cards. We've been tracked in stores since those things came out. Then you get to the checkout and unless you pay cash for everything...well, you know drill. On the bright side, some stores employ people who have the job of returning lost keys based off the shopper cards. So...that's good. While I've never had an issue, I'm sure the scammers are spoofing the codes that change every few moments.
