Ibeacons are used to determine if the fob’s have been removed from the office suite. I chose USB Ibeacons to obviate battery replacement. The beacons can be plugged into a common 5V USB phone charger.

Since the office suite encompasses 3 of the public restrooms’ walls. I placed a beacon inside the suite on each of the shared walls.

One of the walls is in the reception lobby where the key fobs are kept. Therefore, the key fobs stay in range of the beacons while carried to the restrooms but if a guest wanders off the fob icon will change colors. Green indicates 3 beacons in range, yellow equals 2 beacons, orange equals 1 beacon. Red indicates out of range of all beacons.

Once out of range, the fob will play a warning tone and the following message.
