    摘要： Apparatus and methods in which one or more elemental taggants that are extrinsically placed in an object are detected by x-ray fluorescence analysis to identify or authenticate the object are described. The taggant is manufactured as part of the object or the taggant is placed into a coating, packaging, label, or otherwise embedded onto the object for the purpose of later verifying the presence or absence of these elements by x-ray fluorescence. The taggant is then analyzed by XRF and the analysis is then converted into a 2D symbol format that can be used in various security and authentication applications. By using x-ray fluorescence analysis, the apparatus and methods of the invention are simple and easy to use, without the limitations experience by current anti-counterfeiting technologies.

    摘要： An apparatus and method in which one or more taggants that are intrinsically located—or extrinsically placed—in an article or product, such as carpet. The taggants are detected by x-ray fluorescence analysis to identify or verify the article or its point of manufacture. The taggants are manufactured as part of the article or the taggant is placed into a coating, label, or otherwise embedded within the article for the purpose of later verifying the presence or absence of these elements by x-ray fluorescence, thus determining the unique elemental composition of the taggant within the article.
