Abstract: An authentication system, wherein an RF tag stores a first facial feature point extracted from a captured image of a user's face. In an authentication device, a wireless communication unit wirelessly reads and writes information from and to the RF tag. A controller adjusts wireless communication conditions of the wireless communication unit, and estimates a position of the RF tag according to a distance to the RF tag. The controller adjusts imaging conditions of an imaging unit. A position of the user is detected according to an imaging resulting from the imaging unit. A second facial feature point is extracted from an image of the user's face captured by the imaging unit, and is collated with the first facial feature point read from the RF tag. Based on a collation result, authentication of the user is performed.

Abstract: An airline baggage management system includes a boarding reception device; a loading reception device; and a server. The boarding reception device outputs a baggage tag with an RF tag in which tag information is recorded, the tag information including at least one of a user ID, a boarding pass ID, and a baggage ID. The loading reception device includes: a loading reader unit that performs wireless communication with the RF tag of the baggage tag attached to the baggage has arrived at the loading position to read the tag recorded in the RF tag; an information generating unit generates loading position-related information, which is related to a position in the scheduled boarding plane at which the baggage whose tag information has been read by the loading reader unit is to be loaded; and a loading transmission unit transmits the tag information and the loading position-related information to the server.
