IBeacon is Apple's brand name for this kind of technology. To be allowed to collect the MAC-Address which is specifically needed to enable this feature, you have to Allow the Location Services to give Bluetooth access to it. Apple requires a proof of the necessity of using permanent Location Services. Therefore, we sent them a test kit of our product to let them test the need for it and it was approved. Otherwise, it would not have been able to provide our MeatStick App on the App store.
