Claim 6:
7. The maintenance method for the substrate processing apparatus according to claim 6,
the step of maintaining further includes:
transmitting authentication information corresponding to the substrate processing apparatus using the first near field communicator when the access information is transmitted using the first near field communicator, in the authentication device;
receiving the authentication information using the second near field communicator and storing the received authentication information as subject information when the authentication device is present in a communicable range of the second near field communicator of the instruction terminal and the authentication information is transmitted using the first near field communicator, in the instruction terminal;
causing the instruction terminal to hold the storage medium in a communicable range of the second near field communicator of the instruction terminal;
acquiring authentication information stored in the held storage medium using the second near field communicator with the storage medium held, in the instruction terminal;
determining whether the acquired authentication information matches the stored subject information, in the instruction terminal; and
allowing access to the maintenance instruction device in a case where the acquired authentication information matches the subject information, and restricting access to the maintenance instruction device in a case where the acquired authentication information does not match the subject information, in the instruction terminal.
