PROBLEM TO BE SOLVED: To make discriminable an imitation commodity by incorporating an invisible ID information recording means in commodities. SOLUTION: In the case of manufacturing commodities based on a license contract, LC tags 1 are embedded inside respective commodities 21, 22. When a transmitting/receiving antenna unit 14 or 15 for a reflected wave analyzer 11 is brought close to each commodity, the resonance frequency of the tag 1 is specified and a voice message such as a brand name, an article name and a commodity instruction is broadcasted from a speaker of the analyzer based on display data related to the resonance frequency, thus a genuine commodity is certified. |
