Does QR code show location?

A QR code can show the code owner an approximate location of each scan — typically the city or region, derived from the scanner's network (IP) address — but not a precise GPS position. That requires a dynamic (trackable) code; a plain static code reports nothing at all, to anyone, ever.

For scanners worried about privacy: scanning a QR code does not hand over your GPS coordinates, name or phone number. City-level network geolocation is the same information any website you visit can see. A destination page can ask for your precise location, but that triggers the normal browser permission prompt you can decline.

For businesses, city-level data answers the useful question anyway: which market, venue or campaign region is actually scanning.
