1. A communication terminal comprising:
a memory configured to store identification information associated with a user;
a controller configured to authenticate the user;
a communication interface configured to transmit a signal over radio waves including the identification information; and
wherein the controller is configured to:
set, when authentication of the user is successful, the communication terminal to a first state in which the signal is transmitted to an external apparatus;
set, when authentication of the user is not successful, the communication terminal to a second state in which the signal is not transmitted to the external apparatus;
prevent, when a distance between a blocking member and the communication interface is equal to or less than a threshold value, the transmission of the signal by the communication interface to the external apparatus; and
allow, when the distance between the blocking member and the communication interface is greater than the threshold value, the transmission of the signal by the communication interface.
