First Claim
Patent Images
1. A method of installing an IC tag, the IC tag including an IC chip and an antenna, the method comprising:
- providing the IC chip with electrical breakdown means for electrically breaking down an internal circuit thereof and breakdown activation means activated in response to externally applied force for transmitting a breakdown signal to the electrical breakdown means; and
activating the breakdown activation means as required.

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.
