Abstract
To discriminate counterfeit articles by incorporating invisible ID information recording apparatus in the true articles. An LC resonance tag 1 is buried in the articles 21 and 22 at the time when they are being produced in compliance with the contraction of a license. Upon bringing transmission and reception antenna units 15, 16 of a reflected wave analyzer 11 close to the articles, the resonance frequencies of the LC resonance tags 1 are specified, and voice messages such as brand, name of article, explanation of article, etc. are produced from a speaker of the reflected wave analyzer 11 based on the display data related to the resonance frequencies, verifying that the articles are true ones.
