Digital Product Passport

Digital Product Passport (DPP)

A Digital Product Passport is a structured digital record that captures a product's lifecycle data -- from raw material sourcing through manufacturing, distribution, use, and end-of-life recycling. The European Union is mandating DPPs as part of its Ecodesign for Sustainable Products Regulation (ESPR), with RFID positioned as a primary technology for linking physical products to their digital records.

Regulatory Context

The EU ESPR regulation requires DPPs for categories including textiles, batteries, electronics, and construction products, with phased implementation beginning in 2027. Each DPP must contain information on material composition, carbon footprint, repairability, recycled content, and supply chain provenance. The regulation specifies that products must carry a machine-readable data carrier that links to the DPP -- RFID tags, QR codes, or NFC are all eligible technologies.

Why RFID for DPP

RFID offers distinct advantages over optical codes for DPP compliance. An EPC-encoded UHF tag provides a globally unique, serialized identifier that can be read without line-of-sight, through packaging, and at high speed during logistics operations. Unlike QR codes, RFID tags can be read in bulk -- enabling automated DPP verification at receiving docks and customs checkpoints.

For textiles, RFID tags are already widely deployed for item-level tagging in retail. Extending these existing tags to serve double duty as DPP carriers is a natural evolution. Laundry tags embedded in garments persist through the product's useful life, enabling consumers and recyclers to access the DPP data years after purchase.

Data Architecture

The DPP itself is a cloud-hosted record, not stored on the tag. The RFID tag carries an identifier (EPC or GS1 Digital Link URI) that resolves to the DPP data through a discovery service or resolver API. This architecture allows the DPP to be updated over time -- adding repair events, ownership transfers, or recycling instructions -- without modifying the physical tag.

EPCIS provides the event data model for populating DPPs with supply chain traceability events. Each step in the product's journey -- source tagging, warehouse receipt, retail sale, consumer return -- generates an EPCIS event that enriches the DPP record.
