A geofence is a virtual perimeter for a real-world geographic area. A geo-fence could be dynamically generated or match a predefined set of boundaries. The use of a geofence is called geofencing, and one example of use involves a location-aware mobile device of a location-based service user entering or exiting a geo-fence.
Geo fencing can be created using GPS or NFC or RFID technologies
There are many applications for this including such as turning on or off the lights of your home, receiving coupons when you enter a store area etc.
Geotagging, is the process of adding geographical identification metadata to various media such as a geotagged photograph or video, websites, SMS messages, QR Codes or RSS feeds and is a form of geospatial metadata.
In the business world, the most common application of geo fencing and geo tagging is the using it to ensure the location integrity of employees when they mark their presence in the field. Geo tagging is commonly used when employees, such as the sales or service force report their presence by marking their location at specified areas.
Geo fencing, is used extensively when a certain activity such as capturing time and attendance happens only at a pre-determined location, such as branch offices , project sites, retail outlets etc. These locations are marked with latitude and longitude and the mobile devices on which attendance is marked will activate only in this geo fence.
Typical examples are Infrastructure and Construction , Oil and Gas, Solar Power plants, Mining, Plantation. This is because most of their work force is at project sites. There are various types of geo fencing options for various applications and here are a few
1. Radius/Centroid Geofencing
This is the default geo fence where thelocation where the geo fence is active is a red spot with a radius. The radius can be set to custom limit, such as 20 meters to 120 meters. This is typical for a small to medium size project sites. It is also possible to create multiple radius geo fences.

3. Line Geofencing
Line geo fencing is a type of polygon geo fencing which is drawn to specifically create geo fences in narrow stretches and constantly shifting as in vertical integration projects . When your workforce in engaged in building Expressways, Metros, Agricultural canals or laying Railway tracks, Transmission cables which inherently require the work force to move constantly, geo fences are created to be active in a narrow stretch along the path of alignment with a boundary of say 100 m either side, to indicate their work spot.
4. Proximity Geofencing
This is type of geo fence is used when the geo fence has to be active in vertically separated areas such as multiple floors of the same building or in a very small area within a building where GPS is not effective. This is done by creating the geo fence by a triangulating method to within a 5 feet radius.
While these geo fence methods ensure the trustworthiness of the attendance data, it is interesting to know that there are cases in which the geo fences itself can itself be spoofed by faking the geo fence. It is important to guard against this mal practice, which can reduce the reliability of the data.
At FaceTagr, our evolved Geofencing solutions not only give you the option of deploying the geo fencing method that is most suited to your needs, but also detects and prevents spoofing of geo fencing protecting the integrity of the location data. Furthermore, with advanced passive liveliness checks, you can be rest assured that the employee or worker attendance data that is received from multiple sites is reliable and trustworthy, arresting revenue leakages from mal practices.
