A biological information acquisition unit acquires biological information on a subject person. A communication unit transmits the biological information acquired by the biological information acquisition unit to a terminal device that serves as a relay device for relaying the biological information to a management device. A connection destination determination unit, when changing a destination of connection from a currently connected terminal device to another terminal device, determines a terminal device as a new destination of connection in accordance with a content of the biological information relayed by the other terminal devices.
