Apple Updates Apple Store App with Support for iBeacon Systems
The Apple Store app also gives examples of what notifications can be pushed to the devices of in-store customers through the use of iBeacons, such as messages about picking up online orders and store events.
Apple reportedly demonstrated the use of iBeacon systems to the Associated Press in its Fifth Avenue store this week prior to its official rollout today:
The company demonstrated the technology to The Associated Press this week at its busy, 24-hour Fifth Avenue store in New York City. At this particular store, Apple has installed about 20 iBeacon transmitters, some of which are simply iPhones and iPads, which come with the capability as part of the iOS 7 mobile software released in September. The transmitters use Bluetooth wireless technology to sense your exact location. That's not possible with GPS, which don't work well indoors and aren't good at distinguishing between locations that are just a few feet apart.First introduced at WWDC, iBeacon microlocation APIs are designed to access location data through the Bluetooth Low Energy profile on iOS devices, interacting with physical transmitters. The technology first appeared earlier this year, when Major League Baseball announced plans to begin incorporating Apple's iBeacon APIs into its MLB.com At the Ballpark app to create interactive experiences within stadiums in the near future.
The various implementations of iBeacon systems by different companies has also picked up throughout the past few weeks, with some companies such as London based digital publishing startup Exact Editions using Apple's microlocation receivers to deliver location-based access to iOS Newsstand publications. Shopping app Shopkick and Macy's also teamed up for the first retail-based iBeacons last month, allowing customers to find location-specific deals, discounts, and recommendations in the Shopkick app while in a participating Macy's store.
According to an official support page, Apple's iBeacon technology works with Bluetooth capable iOS devices running iOS 7 including the iPhone 4S or later, iPad (3rd generation) or later, iPad mini or later, and the iPod Touch (5th generation) or later. The Apple Store app is a free download for iOS devices, but the new functionality does not require users to download an updated version from the App Store. [Direct Link: iPhone/iPad]
