From Make Magazine’s post:
Eddystone is cross-platform, and open source, distributed under the Apache v2.0 license. While support is built into Google Play Services’ Nearby API on Android, it also has library support for iOS.
The cross-platform and open source nature of this protocol is great, as is the ability to broadcast a URL, something that iBeacon doesn’t do. This comes with some security concerns, but those can be remedied.
I’m looking forward to seeing wider and more innovative use of this beacon technology, especially beyond the most obvious retail/marketing channels.
