Apple’s Find My system could be used to send data from non-internet-connected devices. The data would be broadcasted via BLE and picked up by nearby Apple devices on the Find My network. Such a technique could also be used in other ways to transfer data without Wi-Fi or mobile internet. The system is designed so that there is no access for Apple to the users location, which is only encrypted with the correct private key, on the owner’s device. The method was developed by the University of Darmstadt, Germany.”]
