Geofences are the counterparts to beacons. While beacons are used for more specific proximity, such as letting you know when someone is close to a specific object, a geofence provides more general information such as when a person has walked by a storefront or visits a general area.
How it Works
Geofencing works in conjunction with Google Maps and other mapping programs, allowing you to create shapes (such as circles) to paint general areas or to tag specific buildings or other locations. Once you’ve tagged the desired locations, you can monitor your geofences via your smartphone. This can be useful for security and monitoring (giving you information as soon as someone enters the area and recording how long they were there) or as part of your mobile marketing (allowing you to trigger specific messages when a customer is in the optimal time and place).
When to Use Geofencing
How Does Geofencing Work?
While geofencing has historically relied on cellular data, modern geofencing combines has moved to using GPS and Wi-fi data more. This allows users to opt-in for things like location services and can receive push notifications to keep them updated. You can use “active” or “passive” geofencing, though passive is superior for many reasons.
For instance, while active geofencing can let you track individual customers by latitude and longitude through GPS by contacting a satellite, it consumes so much power that it devastates the user’s battery. This kind of GPS-based geofencing also only works while the app is open, which isn’t really compatible with busy customers bustling by your store.
By contrast, passive geofencing works in the background and consumers very little power, but it gives you less data about the customer and gives you fewer opportunities to reach out to customers, gather data, and transmit the kinds of messages mentioned in the previous section.
Ultimately, it is up to you and your company to calculate the risk versus reward of active versus passive geofencing. In addition to draining more of the user’s battery, active geofencing does risk the customer asking themselves if your app is worth what it delivers when factored against the drain on their battery life.
However, passive geofencing means that you are unable to do what geofencing is arguably designed for: to reach out and engage with customers by offering them relevant information and rewards that make them value your company over the competition.
