1. A communication system that performs a first communication and a second communication, which differs from the first communication, through wireless connection between a terminal and a communication peer, the communication system comprising:
communication devices arranged in the communication peer,
wherein the communication devices include a first communication device and a second communication device, which differs from the first communication device,
the first communication device is connected to a controller that controls the communication devices,
the second communication device is connected to the first communication device and communicably connected to the controller through the first communication device,
the first communication device is configured to control actuation of the second communication device,
the first communication is performed to verify authenticity of the terminal through communication between the terminal and the communication peer,
the second communication is performed to measure a distance between the terminal and the communication peer by using radio waves transmitted and received between the terminal and each of the first communication device and the second communication device,
the first communication device is configured to notify the controller of a first result of the second communication performed by the second communication device and to notify the controller of a second result of the second communication performed by the first communication device, and
the controller is configured to control actuation of the communication peer in response to any one of the first result or the second result indicating that the distance is valid.
