Abstract: Communication accessories, such as keyfobs (KFs) and/or transmitter/receiver dongles, which can transmit and receive signals to enable connectivity between owners of different portable devices even when the devices are off or when in a sleep mode, are described. In some examples, the keyfobs and/or the dongles are programmed with connectivity tokens, such as being programmed with Facebook (FB) information, FB accounts or FBIDs, LinkedIn ID, or generically social network user information, that can be used to authenticate different smart portable devices belonging to different users to facilitate networking. Once the keyfobs and/or dongles are authenticated, they will buzz, sound, or otherwise alert their respective owners that one or more social network users, such as a FB user or a LinkedIn user, are within the general vicinity and that further actions through smart portable devices may be needed to connect the users.
