Apple has integrated AirDrop service into both iOS devices and Mac OS X computers to facilitate file sharing. Documents can be transferred between AirDrop-capable devices and computers directly via Wi-Fi and Bluetooth using the AirDrop protocol. AirDrop can transfer files of any size wirelessly, avoiding the need for email, messaging, external drives, or cables between devices to swap files.
AirDrop was first introduced in iOS 7 and is accessible through the Control Center. When it comes to Mac computers, the machine must be running OS X 10.7 (Lion) or later to connect. Click here for a full list of AirDrop compatible devices and computers.
