The concept of geofencing has always been something associated with the marketing of services. And I am sure you know what that concept is all about, even if you have never known it by its actual name.
We say that a person is geofenced when he moves within a certain area. Marketers set up campaigns that are triggered the moment that happens, and they send special discounts and offers to the person straight to his mobile.
Services that geofence others for personal reasons, now, are not that commonplace. But it looks as if that’s about to change. Footprint is a service that will let you geofence yourself and have your position instantly shared with your contacts on Facebook and Twitter, as well as via email and RSS.
Footprint is presented as a mobile app, and (from a technical angle) it works by using Google Latitude to monitor exactly where you are. It is all based on the position of your phone.
It is clear that this service wants to be a check in killer. The way it works, you will be able to set messages that will be triggered when you arrive somewhere (IE when you return home, or when your plane has landed). And you can also set Footprint to check out automatically for you.
You can get Footprint for free on the site. And a paid version giving you email notifications and 50 free text messages is likewise available.
