Abstract: Secure handoff among devices during media playback. Playback of media, from one or more sources, on two or more respective devices is performed in an automated or simplified manner based upon a near field communications (NFC) or like security pairing transaction between those devices. The security pairing may provide direction for any of a number of operational parameters by which the media is to undergo playback on the different respective devices (e.g., source of the media, quality of the media, digital rights management (DRM), an authentication, authorization, and accounting (AAA) protocol, etc.). Certain implementations allow for user interaction to augment or override automatic or seamless operation between the respective devices for continuous playback of media thereon. Successive security pairings may be performed within any of a number of respective devices (e.g., from a first device to a second device, from a second device to a third device, etc.).
