The Read-Write-Own of Digital Product Passports

If you're managing durable goods, you already know the hurdles: staying compliant with ever-evolving regulations, ensuring seamless collaboration across complex supply chains, and keeping customers engaged long after a product leaves your warehouse. Balancing these priorities isn’t easy, especially when outdated systems make it harder to track, maintain, and connect with products throughout their lifecycle.

We get it! That’s why we develop open and interoperable Digital Product Passport (DPP) solutions designed to help you tackle these issues head-on while unlocking new growth avenues. 

Here’s our three-level approach to DPP.

1. READ: Making Transparency Effortless

With regulations like AGEC already in effect and ESPR on the horizon, the need for businesses to remain compliant is more urgent than ever. You’re under pressure to provide detailed product information while maintaining data accuracy across lifecycles.

At its most fundamental level, a DPP allows stakeholders to read critical information about a product—its origins, components, and impact—by scanning a QR code, tapping an NFC tag, or following a digital link. This data, pulled directly from your systems, builds transparency and trust. 

With Arianee, you can:

• Streamline Product Data Integration: Unify and standardize product data, from materials to certifications, by integrating information from your PLM and PIM systems.
• Ensure Transparency: Give stakeholders—from manufacturers to recyclers—access to the right data when they need it.

For many brands, this is where their DPP journey begins and ends. But we believe this is just the starting point.

2. WRITE: Building Collaboration into Every Stage

Durable goods—whether it’s a car, an appliance, or a luxury watch—continue to evolve long after they’re sold. These items are repaired, serviced, upgraded, and often passed from one owner to another, living many lives beyond the initial purchase. To truly unlock their full value, every interaction along their journey needs to be captured, creating a rich and evolving product narrative.

While the read layer of a Digital Product Passport (DPP) provides insight into how a product is made, the write layer captures what happens next. It enables stakeholders—consumers, manufacturers, retailers, and recyclers—to document the product’s ongoing life. The result is a transparent and collaborative record that supports sustainability, strengthens trust, and extends the product’s lifecycle.

However, with so many players involved in a durable good’s lifecycle, the question arises: how can these contributions be seamlessly integrated without losing critical data or duplicating efforts?

Why our infrastructure is built for post-sale event documentation:

• A Standard for All Stakeholders: The Arianee Protocol is built on open-source standards, allowing anyone to implement and use it to document post-sale events. This creates a consistent approach, so no matter who contributes—brands, retailers, or recyclers—the process is seamless and standardized.
• Create a Trustworthy Data Trail: Allow authorized stakeholders to enrich the product’s history with maintenance records, repairs, or ownership changes. 
• Tamper-Proof Writing: Every update is tamper-proof and auditable,  creating the conditions for a trustless environment where players in the value chain don’t necessarily have to trust each other.
• APIs for Easy Integration: To simplify adoption, we provide APIs that make it easy to add events to the DPP. Whether it’s a warranty claim or a repair record, stakeholders can update the product’s history without technical hurdles.
• Access Rights Management: Post-sale events involve many players, from maintenance providers to recyclers. Arianee’s solution ensures only authorized stakeholders can contribute updates, while sensitive information is protected with need-to-know permissions. For example: auditors might see full details, while service providers only access what’s relevant to their role.

3. OWN: Empowering Your Customers and Unlocking New Opportunities

How do you stay connected when ownership changes hands? It’s the Own level that unlock entirely new use cases for brands, creating deeper relationships and post-purchase engagements with customers. Ownership in this context is more than just holding a product—it’s about engaging with it in new ways.

With Arianee, you can:

• Enable Digital Ownership: Arianee’s onchainDPPs are owned and transferable through users’ wallets. This means ownership of the digital passport moves seamlessly with the product, whether it’s resold, gifted, or recycled. Brands can continue to provide value by giving successive owners access to: Warranties, Maintenance schedules, Resale options. 
• Stay Engaged: Arianee’s Decentralized Message feature allows brands to communicate directly with the current owner—no matter how many times the product is resold. By leveraging ownership data, brands can deliver personalized updates, send reminders, and share relevant offers, all while respecting privacy. This creates an ongoing dialogue that strengthens the relationship between brands and their customers, even after the initial purchase.

Here’s an example: Let’s say you’re a homeowner with a high-end smart refrigerator. Through its DPP, you read about the energy efficiency ratings and environmental benefits of the fridge when you first purchase it. Over time, you notice it needs some maintenance. A certified technician performs a repair and writes the service history directly into the DPP, updating its lifecycle data. Years later, you decide to upgrade to a new model and sell the fridge. With the own feature, you transfer the ownership digitally. The new owner now has a complete history of the fridge’s lifespan, repairs, and warranty status—all of which could boost the resale value and maintain a connection between the new owner and the original brand.

Building the Future with Digital Product Passports

So, the next time you think of a Digital Product Passport, remember it’s more than a QR code on a tag. It’s a tool that holds promise far beyond compliance, but only when thoughtfully designed and utilized. It’s the gateway to a new era of product ownership—one where every read is a chance to build trust, every write contributes to a richer story, and ownership opens doors to a more circular economy.
