Claim 1:
2. The maintenance device for the substrate processing apparatus according to claim 1, wherein
the information transmitter transmits the authentication information corresponding to the substrate processing apparatus using the first near field communicator when transmitting the access information using the first near field communicator, and
the instruction terminal further includes
a subject information storage that receives the authentication information using the second near field communicator and stores 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,
a medium holder that holds the storage medium attachably and detachably in a communicable range of the second near field communicator of the instruction terminal,
a second authentication information acquirer that acquires authentication information stored in the storage medium using the second near field communicator with the storage medium held by the medium holder,
a second determiner that determines whether the authentication information acquired by the second authentication information acquirer matches the subject information stored in the subject information storage, and
an access controller that allows access to the maintenance instruction device using the network accessor in a case where the authentication information acquired by the second authentication information acquirer matches the subject information, and restricts access to the maintenance instruction device using the network accessor in a case where the acquired authentication information does not match the subject information.
