Abstract
An IC chip in an IC tag is provided with a voltage application terminal in connection with its internal circuit, and a high voltage or a reverse voltage is applied to the voltage application upon unlawful handling of the IC tag, so that the IC chip is electrically broken down. In this way, an IC tag installed in an item is prevented from being misused when the IC tag is no longer necessary or being removed for misuse.
