iBeacon transmitters use Bluetooth 4.0 tech, and can be dialed in to a range of different distance sensitivities, which means that it can work on a hyper local basis, sending specific information only when you’re in the area for demos and workshops, for instance, or next to a particular product display. At the same time, it can provide general alerts to anyone who enters a store’s doors.
The upside for retailers using iBeacons is two-fold: First, they can offer more specific, targeted information to customers, which in theory helps with customer service (and could cut down on minor requests that would normally occupy staff). Second, iBeacons provides them with hyper-local data regarding customer movements within a store (apps could contain an opt-in for allowing use of that info). That kind of granular look at shopper behaviour could pay huge dividends in terms of helping formulate evolving retail strategy.
