Human-body communication apparatuses and methods of exchanging information thereof are disclosed. A human-body communication apparatus includes a processing module and a human-body communication module coupled to the processing module. When a user comes in contact with another user, the human-body communication module is configured to establish a wireless connection with the human-body communication apparatus of the other user. The processing module is configured to obtain a time duration of the wireless connection, compare the time duration with a preset first time threshold, and exchange information with the human-body communication apparatus of the other user via the human-body communication module, if the time duration is greater than the first time threshold. Thus, the present disclosure can allow interaction of information through body contact, increasing the user experience.
