Geofencing can be used to create a virtual perimeter for a geographic area or location. As soon as a person enters that particular area his/her mobile phone signal can be detected. Based on this a marketer can decide to show him/her a targeted ad or personal message. This gives marketers the option to show their ads or content exclusively to consumers who meet certain location requirements.
