Embodiment Construction

[0025] While the invention is susceptible to embodiments in different forms, one or more presently preferred embodiments of the invention are shown in the drawings and described hereinafter, it being understood that these disclosures are considered exemplary of the invention, not It is intended that the invention be limited to the particular embodiments shown.

[0026] Radio Frequency Identification ("RFID") tags are becoming more common as the cost of manufacturing tags decreases and the technology to implement RFID systems becomes more common and economical. RFID tags typically include a resonant circuit that resonates in response to exposure to compatible electromagnetic signals. The signal from the resonant circuit is carried to the integrated circuit by inductive or capacitive coupling, via direct connection or electromagnetic ground. Upon detection of the carried signal, the integrated circuit responds by transmitting a responsive electromagnetic signal, which may conta...

Abstract

A method and apparatus for verifying the authenticity of, and detecting tampering with, an item is disclosed. An RFID transponder comprises an antenna resonant circuit which is coupled to an associated integrated circuit when the integrated circuit is positioned proximately to the antenna resonant circuit, thereby enabling the integrated circuit to receive and respond to a radiofrequency query signal. The antenna resonant circuit can be integrated with a capsule or other form of removable packaging, such that it is destroyed upon removal of, or tampering with, the packaging.

Description

[0001] References to related applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 125,519 (filed April 25, 2008), the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates generally to the deterrence or detection of counterfeit or tampered products, and more particularly to radio frequency identification (RFID) tags that can be applied to objects to indicate tampering or counterfeiting of the objects. Background technique [0004] In the market, many expensive products are vulnerable to tampering or counterfeiting. Alcohol and premium spirits are particularly vulnerable to this type of behavior, as these products are often of high value and such tampering or counterfeiting is difficult to detect. Tampering and counterfeiting has become a significant business issue, resulting in lost revenue, reduced consumer trust in product quality and authenticity, and damage to brand v...
