How does mobile geo-fencing work?
Mobile geofencing uses the global positioning system (GPS), internet protocol (IP Address) and longitude/latitude to define geographical boundaries.
When a device enters the virtual geo-fence the phone’s ID is tagged. The mobile identification number (MIN) or mobile subscription identification number (MSIN) refers to the 10-digit unique number that a wireless carrier uses to identify a mobile phone.
We gather information from the tag (gender, age, websites visited, m-commerce and other information). Copley Advertising places ads in mobile apps the user has downloaded. When a user downloads an app they have agreed (via the terms of service) to share information with the company that published the app. When Copley Advertising buys space to place our ad we gather this information.
These tools allow us to drill down to extremely targeted smartphone users in a set location. When the tagged phone leaves the geofence they will still see the ad for 30 days (unless they “wipe” their phone which is rare).
