The goal of this project is to create an anti-counterfeiting system for textiles that takes advantage of advanced materials and mobile readers. Current anti-counterfeiting systems are challenged in achieving the desired characteristics of lack of reproducibility, easy integration of devices into valid products, and simple reading and assessment. We demonstrate the use of non-toxic, fluorescent microspheres for creation of a new class of anti-counterfeiting systems for textiles. Advantages of our system are variation in the nature of the security tag (color and size of microspheres), random and non-reproducible attachment of the particles to the fabrics, and ease of detection of patterns with fluorescent microscope.
