When a user wishes to switch to another device in the middle of a video call, it requires the user to join the already-in-progress call from the other device and subsequently end the call on the previous device. Such an approach is time-consuming, burdensome, and can confuse others in the video call. This disclosure describes techniques to overcome these shortcomings by enabling users to transfer an in-progress video call from one device to another by touching the two devices to each other. User permission is obtained to access call information, which is provided to the target device via a hardware mechanism. An application programming interface (API) is utilized to initiate the video call on the target device and simultaneously terminate it on the source device, thus providing seamless call transfer.
