First it was in Macy's flagship stores in New York City and San Francisco and now it may be coming to a bar, coffee house or mall near you, as first reported by Tech Crunch. The iBeacon is an app that notifies users of specific sales or content that is available to them based on the specific area of the iPhone user.

Tech Crunch said a London-based company is testing the use of iBeacons at specific locations to give users targeted content. 

"The tech is very handy in a number of scenarios, as in a coffee shop for instance, where the establishment could subscribe and enable access to full magazines to patrons who come in," writes Tech Crunch. "It's made even more convenient with the addition of iBeacons on iOS, as the whole digital handshake can happen automatically, providing the user with the best possible and most frictionless experience. Another possible use is in modernizing the doctor's office, offering up publications in the waiting room that are more useful and more current than five-year old issues of Good Housekeeping."

What is iBeacon? According to Apple, "iBeacon, a new class of low-powered, low-cost transmitters that can notify nearby iOS 7 devices of their presence, provides apps a whole new level of location awareness, such as trail markers in a park, exhibits in a museum, or product displays in stores."
