AUTHENTICATION DEVICE, AUTHENTICATION SYSTEM, ROOM ACCESS MANAGEMENT SYSTEM, ELEVATOR DISPATCH MANAGEMENT SYSTEM, POSITIONING SYSTEM, AND SMART DEVICE

摘要

The purpose of the present invention is to provide an authentication device (5) that can set an area in which authentication of a user (3) possessing a smart device (4) can be performed stably, and the smart device (4) corresponding to the authentication device (5), as well as to provide an authentication system (1), a room access management system, an elevator dispatch management system, and a positioning system in which the authentication device (5) and the smart device (4) are used. The smart device (4) possessed by the user (3) has a magnetic sensor (13) mounted. The authentication device (5) has a fluctuating magnetic field with a strength of a threshold value or greater formed on the entire interior of a collation area (7). When the magnetic sensor (13) detects the fluctuating magnetic field with a strength of the threshold value or greater, and a wireless signal sent by the smart device (4) is received, the authentication device (5) authenticates the user (3) based on the collation information.
