Apple released a new location services technology called the Apple iBeacon. iBeacon is essentially a module that makes a spontaneous Bluetooth connection with a nearby smartphone and exchanges packets of information with it. Stores, arenas and other venues can use iBeacon to promote coupons, special offers and location-based information to potential customers.
Apple iBeacon allows companies to mine data about consumers in real-time. By installing multiple iBeacons in a shopping space, stores can pinpoint shoppers' precise location, monitor their browsing habits and send them promotions that are likely to appeal to them. For example, if a customer is browsing for a music player, stores can use the iBeacon to send them a promotion about a pair of headphones that would work well with the music player.
The iBeacon uses Bluetooth Low Energy, a form of Bluetooth that doesn't need to maintain a consistent connection to share data, instead sending packets of information only when in range with another device.
