An object or an article for a detector or reader has a latent illuminance marker. A light source illuminates the marker and the marker emits illuminance as phosphorescence. A photosensor detects the emitted illuminance, and the decay time is determined. The decay time is checked to provide identification and/or authentication of different types or generations of objects or articles.
