This information terminal (100) is provided with: a reception unit (110) which receives an operation; a measurement unit (120) which measures the reception strength of a beacon signal transmitted from a transmission device (200); a setting unit (130) which, on the basis of the reception strength of the beacon signal measured by the measurement unit (120) when the operation is received, specifies setting information that associates the reception strength of the beacon signal with a plurality of categories related to the distance between the information terminal (100) and the transmission device (200); and an output unit (140) which, on the basis of the setting information, determines, from the reception strength measured by the measurement unit (120) after the setting information has been specified by the setting unit (130), the category among the plurality of categories which corresponds to the positional relationship between the information terminal (100) and the transmission device (200), and executes an ou
