Automatically Take Attendance using iBeacons

With the BeHere app installed, the teacher’s iPad acts as an iBeacon and students entering the classroom with an iPhone, iPad, or iPod touch will automatically appear in the app with a profile picture and name. Students will have to install the app on their device too, but thanks to recent iBeacon improvements in iOS 7.1, they won’t have to even open the app or take the device out of their pocket to be recognized as they walk in.
