Abstract (en)

[origin: WO0137207A1] A method provides information concerning an object, and includes steps of providing the object (230) and encoding information concerning the object by providing a set of taggants (350) in association with the object. The set of taggants contains members having distinguishing physical attributes which may include at least one of color, emission wavelength, size, shape and loading factor which, in combination, are predetermined for encoding information regarding the object. Further steps detect the physical attributes (330) and decode the information from the detected physical attributes. The set of taggants can include at least one of particles, fibers and planchets.
