Abstract:
1. An apparatus for managing information about an integrated circuit tag, comprising: an acquiring unit that acquires three-dimensional position coordinates of the integrated circuit tag located at a plurality of critical points each corresponding to a range of electric-wave output by an antenna of a reader/writer, from a controller that measures a three-dimensional position coordinate of the integrated circuit tag; a storing unit that stores the three-dimensional position coordinates acquired by the acquiring unit; an electric-wave outputting-range determination unit that creates an approximation surface based on the three-dimensional position coordinates in the storing unit, and compares the approximation surface and a three-dimensional position coordinate of an integrated circuit tag for locating, and determines whether the three-dimensional position coordinate of the integrated circuit tag for locating is within the approximation surface or not; a writing unit that writes the three-dimensional position coordinates in the storing unit into the integrated circuit tag; and a display unit that
