Abstract
Components, systems, and methods for gas sensing identification are generally disclosed. In some embodiments, a characteristic of an article (e.g., identity, authenticity, property, product associated information such as age or quality, etc.) may be determined by determining the presence (e.g., an amount) or absence of a chemical compound (or compounds) emanating from the article. For example, the presence or absence of the compound (or compounds) emanating from the article identifies a characteristic of the article. In some embodiments, the chemical compound(s) has been proactively added to the article. That is to say, in some embodiments, the chemical compound is not inherently associated with the article but is added in order to, for example, identify a characteristic of the article.
