For aggregation, we first read all the products identified individually with a Datamatrix code and establish the link with the parcel, which itself is serialized with an SSCC. Or a label may contain both an RFID chip and a Datamatrix code: aggregation follows. All this is much more complex than traditional traceability, because we now integrate all means,...
