Abstract: A suspicious person detection technology which is less likely to cause a blind spot of detection of a suspicious person is provided. A suspicious person detection system detects a suspicious person present in a predetermined area and includes a probe request detection terminal (100) configured to detect a probe request transmitted from a mobile terminal (400) to generate probe information including first identification information specific to the mobile terminal which transmits the probe information, and an analyzing apparatus (200) configured to acquire the probe information from the probe request detection terminal, and, in the case where the first identification information included in the probe information matches none of one or more pieces of second identification information set in advance, transmit suspicious person information indicating that a suspicious person is detected to a predetermined information processing apparatus (300).

Abstract: In a turn management system (1000), whether or not input to an input device (115) is not performed for a predetermined period of time is determined, and a standby screen is displayed when it is determined that the input to the input device (115) is not performed for the predetermined period of time. At the time, a first standby screen is displayed when there is turn waiting in a waiting list, and a second standby screen is displayed when there is no turn waiting in the waiting list. Thus, unneeded issuance of a numbered ticket can be suppressed, and operation interruptions of a worker or the like can be reduced.
