Abstract:
An article identification system includes a transceiver that generates a request signal and transmits the request signal, where the request signal requests information corresponding to an article. A transponder is coupled to the article, receives the request signal, and generates an output signal in response to the request signal, where the output signal includes information corresponding to the article. A loop antenna proximate to the transponder enhances the output signal. The transceiver detects the enhanced output signal and receives the information corresponding to the article.
