An information processing system according to the embodiments includes an in-vehicle device (electronic device), a portable communication terminal, a terminal position computing unit (computing unit), and a specific process executing unit (executing unit). The in-vehicle device is provided in a vehicle (predetermined facility). The portable communication terminal is capable of mutual communication with the in-vehicle device. The terminal position computing unit computes a position of the portable communication terminal based upon a motion of the portable communication terminal. The specific process executing unit, when the position of the portable communication terminal computed by the terminal position computing unit is a predetermined position that is predefined in the facility, executes a specific process corresponding to the predetermined position.
