The DPP in Resale and Second-Hand Markets
How the Digital Product Passport changes resale — authenticity, condition data, ownership transfer and brand-run resale programmes.
Two things limit the growth of second-hand markets: uncertainty about authenticity and uncertainty about condition. The buyer is not sure the item is genuine or how hard it has been used. A Digital Product Passport addresses both directly.
Two frictions, two answers
| Friction | Passport answer |
|---|---|
| Is this genuine? | Item identity plus signed data. See fighting counterfeits |
| How worn is it? | Repair history, usage data, warranty status |
| How was it cared for? | Care records and instructions |
| Are spare parts available? | Parts list and availability period. See the Right to Repair Directive |
Ownership transfer
What happens to the passport when a product changes hands? The practical model:
- The passport belongs to the product, not a person.
- Ownership is handled in a separate, optional layer.
- Personal data is not held in the passport; the ownership record is separate and GDPR-compliant. See GDPR and DPP data.
The battery case
For EV batteries, second life is the most mature passport use case: state of health data determines whether a battery is suitable for stationary storage. See battery state of health and dynamic data.
Brand resale programmes
For brands, resale has moved from threat to revenue line — and the passport is its infrastructure:
- Authenticity is verified.
- Condition is assessed and priced.
- Refurbishment is recorded in the passport.
- The new buyer sees the full history.

A granularity warning
None of these scenarios work with a model-level passport. If resale is a goal, item level is required — and that decision is made in production. See choosing granularity.
Frequently asked questions
Doesn't second-hand selling hurt the brand?
Evidence suggests the opposite: controlled resale protects both second-hand pricing and the customer relationship.
What if the label has been cut off?
Carrier choice is critical. A second carrier such as NFC reduces the risk. See DPP labelling for apparel.
Who records repair history?
Authorised service or the brand. Independent repairers can be enabled through role verification. See DPP access rights.
