Abstract
A communication system includes: a terminal configured to perform a predetermined operation and including a communication device configured to transmit first information relating to the predetermined operation by a first communication method; and a server apparatus configured to receive information transmitted from the terminal. The communication device transmits second information indicating a status of the terminal by a second communication method different from the first communication method, and the server apparatus determines whether the first information is normally received from the terminal and, when determining that the first information is not normally received, performs predetermined processing depending on a communication status of the terminal based on the received second information.
