Geofencing

Geofencing is a location-based app that uses GPS, Wi-fi or mobile data to do a pre-programmed action when you are in an area near certain places. These areas are known as geo-fences.

A geo-fence is a defined area near a location. This location can be, for example, a shop or business. Geofences can be really useful  when you have a business. For example, you can notice when a customer goes to another shop. Burguer King sold Whopper burguers for $0'01  only when their customers were away from a McDonald's. They used geofencing to know where their customers were and when they were near a McDonald's, they received a notification on their phone to make them go to the nearest Burguer King. This is just one way brands are thinking how to use geofencing without invading their customer's privacy.

But not everyone likes geofencing. Some people may not like the fact that brands  can know where they are at anytime. People like to have privacy and businesses sometimes don't respect this.

In my opinion, geofencing has advantages and disadvantages.  It can be very useful if you want new customers to come to your shop. For example, you can notice people when they are near your shop. But I don't like promotions like the one that Burguer King ran. I think that it would be better if Burguer King made a discount on some products if I am a regular customer, not if I am near a shop
