Packs of rod-shaped smokers' products comprise containers of a material which permits monitoring of their contents by a suitable detector serving to generate signals which indicate the presence of characteristic indicia on one or more packed smokers' products. Such signals are encoded and the encoded information is applied to the respective containers. The information can be decoded and compared with signals furnished by the detector in order to ascertain whether or not the smokers' products are genuine, i.e., made by the manufacurer whose trademark(s) and/or other identifying information appear or appears on the containers.
