A Product Is Beginning to Have Its Own Digital Biography: The EU Product Passport Governs Data, Not Just QR Codes

A Product Will Have More Than a Serial Number: It Will Have a Traceable Life History

We are used to products having barcodes, serial numbers, and QR codes. But the European Union's Digital Product Passport, or DPP, is not simply another scannable label. On July 20, 2026, the European Commission officially activated the DPP Registry and testing environment, showing that years of discussion had moved from regulation and standards into operational infrastructure. According to the EU, a DPP is a digital container for product information intended to increase supply-chain transparency, support consumer choice, and support compliance in the single market. Data are stored in a distributed way, while economic operators must register product passports and unique identification information in the Registry.

The change looks technical but is highly institutional. On July 14, the EU published a decision on harmonized standards for the DPP, covering unique identification, interoperability, data carriers, APIs, data exchange, and storage. On July 16, it published implementing rules for the Registry. EUR-Lex | Commission Implementing Decision (EU) 2026/1736 EUR-Lex | Commission Implementing Regulation (EU) 2026/1778 From this point, the DPP's real question is no longer only which fields to include. It is how millions of products, tens of thousands of suppliers, and different roles can work under one set of data rules.

A QR Code Is an Entrance, Not the Passport Itself

Thinking of a DPP as a QR code is an easy way to underestimate it. A QR code or another data carrier only connects a physical product to a digital identity. The complicated part is the data life cycle behind it. A jacket may involve fabric, dyeing, zippers, buttons, membranes, thread, and packaging. A battery may involve active materials, cells, modules, a manufacturer, performance, a carbon footprint, and recycling information. After leaving the factory, a product may be repaired, have parts replaced, be resold, dismantled, remanufactured, or become a material source for another product. If the passport contains only factory data, the circular economy is reduced to a beautiful biography.

The DPP must therefore handle continuity of identity. If an outdoor jacket receives a replacement waterproof zipper, is it still the same product? If a battery module becomes a second-use energy-storage system, how does the new system refer to the original materials and use history? If a repairer replaces a non-original part, who may write the entry? If someone writes it incorrectly, who may correct it? A QR code cannot answer these questions; data models, permissions, and responsibility rules must.

Who Can See What May Matter More Than “Open Data”

Transparency does not mean that everyone sees exactly the same data. Consumers may need material composition, repairability, durability, and recycling information. Customs or regulators may need compliance data. Repairers may need part specifications and disassembly instructions. Recyclers may need material and hazard information. Manufacturers may need to protect supply-chain formulas, process parameters, and commercial secrets. If a passport exposes everything to everyone, companies may resist. If it exposes nothing, the DPP loses its purpose.

The product passport is therefore closer to a role-based data space. Who logs in with which identity, which fields they can read, which fields they can write, and whether every change has a timestamp and responsible party are all foundational design questions. The registration and identity-verification arrangements for the Registry in 2026/1778 show that the EU treats “who is writing this biography” as central rather than treating data as anonymous content.

A Real Circular Economy Needs Products to Remain Understandable After Repair

One of the most common difficulties in a circular economy is that information begins to disappear once a product leaves its original factory. A second-hand buyer does not know its use history. A repairer does not know the part version. A recycler does not know what materials are inside. A remanufacturer does not know which parts can safely be reused. As a result, products that still have value are treated as waste with an unknown information history.

If implemented well, a DPP can fill this gap. Repair events can be recorded, critical part replacements can be updated, second-hand buyers can confirm important information, and recyclers can identify materials more effectively. The value is not in having as much data as possible, but in allowing data to be updated reliably along the product life cycle. Every entry needs a source, version, and responsible party; otherwise, the longer the passport becomes, the more errors it carries.

The EU's Ecodesign for Sustainable Products Regulation places the DPP within a broader sustainable-products policy. Its purpose is not only information transparency, but also durability, repairability, resource efficiency, and circularity. European Commission | Ecodesign for Sustainable Products Regulation

What Small and Medium-Sized Enterprises Really Worry About Is Who Pays for Data Preparation

Large multinational companies may already have supply-chain data platforms, but for small and medium-sized manufacturers the most immediate DPP question is usually cost. Upstream suppliers use different formats: some have only PDFs, some use spreadsheets, and some materials come from long-standing partnerships with no structured data. Companies must also decide which fields belong to them, which must be obtained from suppliers, and who is responsible when supplier data are wrong.

The success of the DPP therefore depends greatly on whether standards and tools reduce the burden on smaller businesses. If every brand creates its own data format, suppliers will have to enter the same information repeatedly. If data models, APIs, and unique identifiers truly interoperate, one act of preparation can be reused across several processes. This is why the 2026 harmonized standards matter: they turn “interoperability” from an attractive policy phrase into an engineering specification.

Two-Eyed Seeing: Supply Chains Know How Products Are Made, Repairers Know How They Age

Product data should not be defined by manufacturers alone. Original producers understand design and materials best, but repairers know where products fail in the real world. Recyclers know which structures are hardest to dismantle. Consumers know the gap between instructions and actual use. If a DPP only sends factory data outward to everyone else, it remains a digital version of a traditional catalogue. Its real value is allowing knowledge from different roles to flow back under appropriate permissions.

For example, if a particular outdoor jacket commonly loses adhesion at one location, an anonymized failure statistic from repairers may help designers change the material. If a battery module performs differently in second use than expected, records from remanufacturers can improve the service-life model. Two-Eyed Seeing does not mean that everyone may edit everything. It means the system recognizes that a product's real biography continues to be written through use.

For Local Brands and Cultural Products, Transparency Still Needs Boundaries

The future DPP also raises a question for local brands: how much origin transparency is reasonable? A small agricultural product, craft item, or regional brand may want to demonstrate the source of its materials, place of origin, and sustainability, but that does not mean it must publish every supplier relationship, craft detail, or sensitive location. A good product passport should distinguish between what can be verified and what can be made public, allowing a claim to be confirmed by a third party without exposing unnecessary details.

This principle also reminds us that digital governance is not a matter of “more data equals more progress.” A mature DPP gives the right people enough information at the right time while protecting content that should not circulate. Transparency, trade secrets, consumer rights, and circular use must be designed together.

A Product Begins to Have Time

In the industrial era, product data often stopped at the moment of manufacture: model, specifications, and price. The DPP makes a product more like an object with a time dimension for the first time. Where did it come from? How was it repaired? Which parts were replaced? Did it enter a second-hand market? How was it finally dismantled? When this information persists, the circular economy has a chance to move from “we hope everyone recycles” to a material flow that can actually be managed.

The significance of the EU DPP Registry going live in 2026 is therefore not a new website. It is the beginning of a system that binds product identity, data responsibility, and the life cycle together. What deserves attention is not how many QR codes we scan, but whether this digital biography can still tell the next user, repairer, remanufacturer, and recycler what they are holding many years after the product leaves the factory.

The Real Difficulty Also Includes Data Becoming Outdated

Once a product biography exists, it faces a problem different from that of an ordinary database: the data are not finished when they are first written. A material supplier may change factories, a part version may be updated, a repair manual may be revised, and regulatory limits may change. If a consumer scans information that is three years old and the system does not clearly show its version and update time, the DPP may create a new form of misplaced trust. A passport needs more than fields; it needs version control, update responsibility, and a traceable record.

This also matters for regulation. If a safety problem is discovered in a particular part after a product is on the market, can the DPP quickly identify affected batches, provide repair information, and let the second-hand market and repair sector know at the same time? If so, the product passport is not only a circular-economy tool; it may also become infrastructure for product safety and after-sales governance. Conversely, if update permissions are too concentrated and erroneous data are difficult to correct, users may mistake a “seemingly official digital biography” for something that is always right. The system must therefore design trust and correctability together.
