20. A product-marking system for marking a product, including:
a product-identification device configured to detect at least one property of the product,
an encoding device configured to determine an encoding to be associated with the property,
a mark-application unit configured to apply a plurality of luminescent materials onto the product to form a mark, and
a control unit configured to control the mark-application unit to apply the mark onto the product,
wherein:
the mark corresponds to the encoding determined by the encoding device,
the encoding specifies a presence or absence of each of the plurality of luminescent materials,
at least one of the plurality of luminescent materials exhibits a predetermined decay behavior,
the product-identification device comprises an optical product detection device that includes at least one camera or at least one color detection sensor, and
the property is a shape of the product determined by the camera or a color of the product determined by the color detection sensor.
