Docking stations for devices such as smartphones, tablets, and laptops lack convenient mechanisms to recognize specific devices owned by specific users, thus requiring the use of pairing mechanisms. However, conventional pairing mechanisms require precise device positioning and can have a negative impact on design aesthetics. This disclosure describes techniques for quick and convenient pairing between devices and docking stations in a manner that permits docking stations to recognize specific devices. Detection of an inertial impulse trigger is performed via IMUs on devices and docking stations to determine when a device is docked. The initial trigger is followed by an ultrasonic handshake between the device and the docking station using respective speaker-microphone pairs. The ultrasonic handshake is used to recognize specific devices via a secure phase-modulated key that is unique for each device.
