My telco is most definitely not able to determine which particular restaurant, shop or highrise apartment I visited (I know because I have direct experience with requesting this data from telcos via courts and how precise it actually is).
Telcos can calculate approximately where I was (with accuracy worse than raw unaided GPS - so ±10m at least, and unpredictably wrong if I'm behind a wall or in a vertically built-up area) at a particular point in time - but they don't know the exact timestamp to look for.
> QR codes aren't effective at all as a surveillance mechanism. Why the hell does the government need to monitor which venues you visit based on QR code check-ins? They literally just ask Apple, Google, or any other big tech company about your phones geolocation and IP log history to monitor your whereabouts.
This is about locating a user based on QR code scanned at a venue. All I’m saying: no need to ask Apple or Google. Your telco already knows you have been at a location at the time of the venue.
