Abstract
A method of controlling an aerosol-generating system, and the associated system, are provided. The system includes an aerosol-generating article and an aerosol-generating device having a detector configured to detect the presence of the article and to distinguish the article from other articles configured for use with the system, based on a spectroscopic signature of a taggant incorporated within a material of the article. The method includes detecting the presence of the article; determining whether the article includes a taggant; comparing the spectroscopic signature of the detected taggant with a look-up table of taggant spectroscopic signatures corresponding to articles configured for use with the system; preventing activation of the device, including preventing the supply of power to a heating element unless the detected taggant spectroscopic signature corresponds to an article configured for use with the system; and activating the device if the detected signature corresponds to the article.
