System and method for tracing a product item

A system for tracing a particular product item on a production line comprising a control unit and a timestamp counter, which are comprised on the production line, wherein the control unit is configured to receive a real-time product signal related to the particular product item from peripheral devices of the production line, wherein the control unit is further configured to carry out a method comprising:

• receiving a plurality of real-time product signals, each of the plurality of real-time product signals relating to the particular product item and a peripheral device of the peripheral devices, generating a plurality of event signals, wherein each event signal of the plurality of event signals is based on one of the plurality of real-time product signals and corresponds to an event experienced by the particular product item, arranging the plurality of event signals in a sequence corresponding to an order in which the plurality of real-time product signals was received in order to determine a relative position of the particular product item in the production line, and associating a timestamp generated by the timestamp counter with the sequence, wherein the peripheral devices comprise:
• a counting sensor configured to initially recognize the particular product item on the production line to produce the real-time product signal, the control unit being configured to receive the real-time product signal from the counting sensor to trigger the timestamp counter to generate the timestamp for the sequence of the particular product item such that the timestamp counter generates the timestamp when the counting sensor initially recognizes the presence of the particular product item on the production line, a print head configured to print a digital stamp on the particular product item, the digital stamp reflecting the information with respect to the particular product item obtained from at least one of the peripheral devices, which precedes the print head on the production line, and the timestamp associated with the sequence of the particular product item, and a quality camera which is succeeding to the print head on the production line and is configured to read the digital stamp printed on the particular product item and to issue an event signal whether it is possible to read the digital stamp or not.
