Abstract: A method and a coding line (128) for serializing a plurality of products in a coding line (128), wherein each product is packed in a cuboid box (114), is disclosed. Herein, the coding line (128) comprises at least one slide (132) and at least one main pusher (130) being adapted for jointly moving the boxes (114) on the slide (132) in a row of the boxes (114) through the coding line (128), wherein the coding line (128) further comprises at least one printing system (118) designed for printing a serial code onto each of the boxes (114), wherein the serial code comprises at least one unique serial number, and at least one camera (120) designed for reading the serial code printed on each of the boxes (114).
