A system includes a remote control device configured to remotely control a device and a safety control device communicating with each other via a wireless connection. The remote control device includes a switch, a motion enable unit configured to generate processed information by processing information using a first secret, and a hand control unit capable of acquiring the processed information only when the switch is in a closed state and configured to transmit the processed information to the safety control device via the wireless connection. The safety control device includes a communication unit configured to receive the processed information via the wireless connection and a safety control unit configured to verify the closed state of the switch by processing the processed information using a second secret that matches the first secret and enable control of the device when the closed state of the switch is verified.
