What is iBeacon?

iBeacon sensors create a small, concentrated area of detection. Within the transmission zone, customized notifications can be sent to iBeacon-enabled apps on iPhone, iPad, or iPod touch devices that support Bluetooth 4.0 technology. Customers can be alerted to everything from special offers and discounts to details about a display to personalized messages.

Apple has outlined many potential uses for iBeacon, many of which are in the retail and marketing space. The value of micro-location is undeniable - being able to determine a user's proximity to a known location at an instant in time opens the door for many promotional, analytical, and convenience applications that have not been possible until now.
