Using low-energy Bluetooth beacons to serve up location-based info to customers isn't a new development. We've seen more than a few implementations of Apple's iBeacon tech. Google has a new project that employs a similar setup, and it's called Eddystone. How does it differ from Apple's Bluetooth initiative? The effort is a "new and open format" that "anyone" can implement. In addition to working alongside a mobile app to beam info to your phone or tablet when you're in a specified location, Eddystone can also broadcast a URL when an app isn't an option. Rather than missing out, a company can choose to send a web link instead. And it works with both Android and iOS devices, too. There are also two location options, meaning developers can choose one of two APIs that will either find and ping a nearby beacon (like in a museum) or send info when you visit a specific location (e.g., latitude/longitude).
