Geolocation

Geolocation determines a device's geographic position (latitude and longitude) using GPS satellites, Wi-Fi access points, cell towers, and IP addresses. Web browsers provide the Geolocation API for accessing location data with user permission.

QR codes and geolocation combine in two directions. First, scan location recording and analysis. Adding geolocation data to dynamic QR code access logs reveals which regions generate the most scans and which store locations see the highest usage - valuable for multi-location campaigns.

Second, location-based content delivery. The same QR code can redirect to Japanese pages when scanned in Tokyo and English pages in New York. This powers multilingual tourist guides, regional event information, and geo-targeted promotions.

From a privacy perspective, geolocation data can reveal personal movement patterns. Browser Geolocation API requires explicit user consent, though IP-based approximate positioning may occur without permission. QR code access logs collecting location data must disclose this in privacy policies and minimize data collection.
