Abstract
A method of tagging and detecting objects is disclosed which comprises the steps of: (a) applying a volatile taggant to the object; and (b) subsequently detecting the presence of the taggant by the absorption, transmittance, reflectance, photon emission or fluorescence of the taggant and therefore a proximity of the tagged object. The present invention therefore provides optical sensing means which do not require physical separation of differing compounds for discrimination thereof.
