Digital Product Passport

At Prooftag, the Digital Product Passport (DPP) is a standardized digital identity assigned to physical products.
It supports regulatory compliance, product traceability, and access to reliable product information across the value chain.
The DPP enables products to carry verified and structured data over time, accessible through standardized digital carriers such as QR codes, DataMatrix, RFID, or NFC.

Purpose of a DPP
The implementation of the Digital Product Passport is driven by:
• European regulatory frameworks, including Ecodesign, ESPR, and sector-specific regulations
• Requirements for transparency, sustainability, and traceability
• Expectations from authorities, market surveillance bodies, and consumers for reliable product data
• The need to prevent counterfeiting, fraud, and greenwashing
The DPP is a regulatory and structural obligation.

Characteristics
The Digital Product Passport is not a communication or marketing tool. It is not a landing page, a campaign QR code, or a static database.
It is characterized by:
• International standards and GS1-compliant identifiers
• Product- or batch-level identification
• Data governance covering integrity, access management, and traceability
• Long-term data availability
• Interoperability with authorities, partners, and digital platforms

Prooftag’s DPP framework
Prooftag approaches the DPP as a product identity infrastructure.
This framework is based on:
• A unique and persistent product identity
• A secure physical–digital link
• Controlled access to data for use cases including regulatory compliance, supply chain traceability, market surveillance, and consumer information
Prooftag ensures data reliability and integrity across all uses.

Technical foundations
Prooftag’s DPP relies on GS1 QR codes and DataMatrix, serialization and Track & Trace systems, and secure data management and governance mechanisms.
These technologies are interoperable and scalable across multiple industries.
