Claim Text:
1. A method for communication session transfer between a plurality of computing devices, the method comprising: detecting, by a first computing device, a presence of a second computing device in proximity to the first computing device, wherein the first computing device has established a first communication session with a remote computing device; establishing, by the first computing device, a wireless connection to the second computing device; transmitting, by the first computing device, a first token generated by the first computing device to the second computing device, wherein the first token includes a pre-stored shared key and an identifier associated with the first computing device and the first token is configured to render the first token invalid if copied for use as an identifier for another device; receiving, by the first computing device, a second token generated by the second computing device from the second computing device, wherein the second token includes the pre-stored shared key and an identifier associated with the second computing device and the second token is configured to render the second token invalid if copied for use as an identifier for another device; authenticating, by the first computing device, the second token via comparison to the first token; and transmitting, by the first computing device to the second computing device, information indicating a state of the first communication session to enable the second computing device to establish a second communication session with the remote computing device, wherein the second communication session is established using the state of the first communication session.
