PATINA FAQ: Digital Product Passports & Post-Purchase for Fashion Brands

PATINA (patina-os.com) is a post-purchase platform for fashion and luxury brands, built on Digital Product Passports (DPPs). It is the rules engine that decides what happens every time a product is scanned, for the life of that product. It powers resale, repair, take-back, authentication, warranty, care and loyalty after the point of sale.

No. The DPP is the legal requirement; PATINA is what brands do with it. Most DPP providers stop at a static compliance record. PATINA turns the same passport into a live post-purchase channel, so every scan can drive resale commission, repair revenue, first-party customer data and loyalty, not just display product information.

Most DPP software focuses on collecting supply-chain data and publishing a compliance page. PATINA starts where those stop: after the sale. It manages ownership, resale, repair, take-back and customer engagement for each individual product. It works alongside the compliance and data tools brands already use, and it is built on open GS1 standards, so brands are never locked into a proprietary ID.

The EU's Ecodesign for Sustainable Products Regulation (ESPR) has been in force since July 2024, and textiles are among the first product groups prioritised. The delegated act setting the detailed textile DPP requirements is expected in 2027. Brands will then have an 18-month window to comply. Brands that set up DPPs now get the commercial benefits before the deadline arrives.

Yes, if they sell into the EU. ESPR applies to products placed on the EU market, wherever the brand is based. A UK or US brand selling to EU customers, directly or through retailers, will need DPPs for those products once the textile rules apply.

PATINA structures the data DPP regulation calls for: a persistent product identity plus material, origin and lifecycle information. It also supports Extended Producer Responsibility (EPR) needs around traceability and end-of-life handling. Because the textile delegated act is still being finalised, PATINA is built to adapt as the detailed requirements are published, so brands aren't rebuilding later.

The EU DPP registry is the central EU system that will hold the unique identifiers of every product with a Digital Product Passport, linking each product to its passport data. It lets authorities, customs and market regulators check that products sold in the EU have a valid passport. PATINA manages the unique product identifiers and passport data the registry will reference, so brands are ready to register their products when it launches.

No. ESPR doesn't require blockchain. A DPP needs a persistent, unique product identity that anyone can scan and that works across systems. PATINA uses GS1 Digital Link, the open global standard behind retail barcodes. It gives every product an interoperable identity without the cost and complexity of blockchain.

GS1 is the global standard already behind product identification and barcodes across retail and supply chains. Building on GS1 Digital Link means every PATINA product uses an open, interoperable identity rather than a proprietary one. It works with the product data brands already have, matches how DPP regulation is expected to be implemented, and doesn't lock brands into an ID system they can't take elsewhere.

With PATINA, every scan is a commercial opportunity, not just a compliance check. Brands can route resale through their own channels and earn commission instead of losing it to third-party marketplaces. They can also unlock repair and service revenue and turn each product into a direct channel to the customer that doesn't depend on email or ad platforms.

Yes. Each product on PATINA has a unique, scannable identity linked to the brand's own records, so buyers and resellers can check it is genuine and see its history. That trust makes second-hand sales easier. Brands can run resale through their own channels and keep the value, rather than losing it to marketplaces.

When a customer scans their product, PATINA shows the options the brand has set for that item: care guidance, booking a repair, trading it in, or returning it at end of life. Brands without their own repair or take-back operations can route requests to specialist service partners and offer these services without building them in-house.

Customers register ownership by scanning the product, which links them to that item and activates its warranty, with no receipts or paperwork. The brand gets a verified, first-party record of who owns what. It can use that record for warranty claims, care reminders and loyalty rewards.

PATINA is built for fashion, luxury and lifestyle brands of every size: SMEs, mid-market brands and global enterprises. Smaller brands can launch Digital Product Passports and post-purchase services without building their own infrastructure. Larger brands can run them across big catalogues and multiple markets, connected to their existing systems. Every brand starts with the core platform and adds modules such as resale, repair, take-back and loyalty as its programme grows.

A pilot is a fixed-scope, time-boxed live deployment. It includes a working scan experience on real product, a configured rules engine, one defined use case (access, ownership, resale or loyalty) and a dashboard showing live results. It ends with a measured readout and a scoped plan for wider rollout.

No. PATINA connects to a brand's existing ERP, CRM, PLM and compliance systems through APIs rather than replacing them. It reads data already held elsewhere and adds the rules and customer experience on top. Brands keep their existing systems as the main record, and PATINA puts that data to work at product level.

The brand does. PATINA isn't the main system of record; that stays with the brand's own ERP, CRM and compliance systems. PATINA reads and uses that data to run rules and experiences. Any customer data captured through PATINA follows the brand's own privacy and consent settings.
