1 iPad + this app, a total solution for promotion/message delivery based on iBeacon technology.
This app will notify iPhones nearby with Beacon One app installed (https://itunes.apple.com/us/app/id725369296?mt=8) , present texts and images it contains.
This mechanism works even without any network nearby, even Beacon One app is not running.
A Beacon Master could be setup by retail store to promote new arrival or discount messages, by stadium to deliver new announcement when people pass by the entrance, by teacher to transfer presentation materials to students iPhone in same classroom, or by a restaurant to introduce todays special, etc.
With iOS multipeer technology, data can be transfered between Beacon Master and Beacon One without cost to users cellular data plan!
With iOS iBeacon technology there is almost no addtional power drain to cells power.
But Beacon Master only works when it is running in foreground, so plug with power supply is highly recommended.
Note: End user will be notified only if there is new message for that specific user, and the specific user havent been notified by the same Beacon Master in last 30 minutes.
