What does "geofencing" mean? Could you give me some examples?
"Geofencing" is a technological term. A "Geofence" is a virtual boundary or parameter for a real-world geographic location. So when a device exits or enters a "geofence", there could be different alerts, adverts, or other things sent to your advice. Other people may not know your exact location, but they can track you in relation to these geofences. Ex: When I got to the mall, I received an email from my favourite store there. Ex: Some countries use geofencing via BlueTooth to track COVID-19 cases. Ex: Geofencing improves marketing. Ex: I went to orientation at my university today and received so many alerts about textbooks for sale. They have efficient geofencing.
