Unique product identification via UPI is used to link the physical product with its information. The UPI can be carried out using DataMatrix, QR codes, RFID tags or other data carriers. These data carriers enable the link to the actual DPP.
At least the following building blocks are central to this:
- Exact designation of the product and the model
- Details of the manufacturer, such as name, address and contact information
- Globally unique product identifier/identification, depending on requirements at product level, lot with article number (type) or serial number (instance) (e.g. EAN, UPC, GTIN, DNP)
- Globally unique identification of the economic operator (e.g. GLN)
- Globally unique identification of locations or buildings involved in the value chain of a product (e.g. GLN)
- CE marking, which indicates that a product complies with the requirements of the applicable EU legislation
- Information on other certifications, standards and safety guidelines
This list is not exhaustive, as other legal acts, for example in the chemicals sector, will require additional characteristics.
The following illustration shows a possible representation and implementation of such a DPP type plate according to the information available at the time the white paper was created.
