<p>A method for product authentication, comprising applying to the genuine products code on a label, the code being generated by an algorithm, which code is unique to a small sub-set of articles, preferably for a single such article, so that it can be assumed that any product on the market which either does not have a label or has a wrong label, or for which the label is otherwise accounted for, is counterfeit, the label being machine readable, such as a writeable RFID tag characterised in that the label comprises a machine-readable microcircuit to which a code can be written, and from which the written code can be read remotely.</p> |
