Future AirDrop could use light for incredibly fast and secure data transfers

Rather than utilizing Bluetooth and Wi-Fi for communicating between iPhone, Apple is looking at Li-Fi — transmitting data using light.AirDrop could gain a more secure version that uses light instead of Wi-Fi and BluetoothApple has used infra-red (IR) transmitter/receivers in Macs, in theory for any short-range swapping of data. In practice, it tended to be used for remote controls such as the Siri Remote, because IR is slow and devices had to be pointed at each other reasonable accurately.More recently, however, a similar idea using light, officially became an industry standard.
