Passports Overview
A Digital Product Passport (DPP) is a structured, publicly accessible record that accompanies a physical product throughout its lifecycle. It presents verified product information — such as materials, origin, sustainability data, and compliance declarations — in a consistent, branded format that consumers and supply chain participants can access by scanning a product’s identifier.
tieback provides the infrastructure to create, manage, publish, and serve Digital Product Passports at scale.
Why Passports Matter
Regulatory frameworks — including the EU’s Ecodesign for Sustainable Products Regulation (ESPR) — are making Digital Product Passports a requirement for an increasing range of product categories. Beyond compliance, passports enable brands to communicate provenance, sustainability credentials, and product-specific information directly to the consumer at the point of interaction.
A well-structured passport:
- satisfies regulatory disclosure requirements
- builds consumer trust through transparency
- provides a durable, scannable record tied to the physical product
- supports supply chain visibility across the product lifecycle
Content, Templates, and Themes
tieback passports are built on a clear separation between content, templates, and themes:
This separation means brands can:
- adjust what information is disclosed without redesigning the visual experience
- change the visual presentation without altering the content structure
- satisfy different regulatory requirements through template configuration
- maintain a consistent, premium consumer experience through curated themes
What a Passport Contains
Each passport is composed of content blocks — structured sections of information that together form the complete passport experience. Blocks cover topics such as:
The specific blocks and fields available depend on the product’s industry classification, the brand’s template configuration, and the applicable regulatory requirements.
How Passports Fit into tieback
Passports build on the existing product and identity infrastructure:
- Products — the structured catalogue record, including schema-driven attributes and identifiers. See Products.
- Identifiers — SKU, GTIN, EAN, and UPC codes that uniquely identify the product. See Identifiers.
- Resolver — the permanent scan URL that maps a physical identifier to a product record. See Resolver & GS1 Digital Link.
- Minting — the process that creates verifiable passport tokens tied to production batches. See Minting Overview.
Passports sit at the presentation layer: they take the product data, apply the template’s content governance, and render the result through the brand’s assigned theme into a public, consumer-facing experience.
Key Concepts
Template-Governed Content
The passport template determines which product data is included in the passport. Even if a product record contains extensive information, only the fields permitted by the active template appear in the rendered passport. This gives brands precise control over disclosure. See Content & Templates.
Themed Presentation
Curated themes control the visual presentation of the passport — layout, typography, colour application, and responsive behaviour. Themes are professionally designed and maintained to ensure enterprise-grade visual quality. See Themes & Presentation.
Published Snapshots
When a passport is published, tieback captures an immutable snapshot of the content as it exists at the point of publication. This snapshot is what the public sees. Changes to the underlying product data do not automatically update the published passport — a new version must be published explicitly. This protects the integrity of the public record.
Brand-Consistent Experience
Passports are rendered with the brand’s visual identity — including logo, colours, and domain — so that the consumer experience is consistent with the brand’s other digital touchpoints.
Assignment-Driven Delivery
Brands control which passport version is served for each product. Assignments determine the relationship between a published passport version and the products or batches it applies to. This gives brands precise control over what the public sees, and when.
Current Scope
Passports in tieback currently support:
- configurable content templates with field-level control
- curated theme-based visual presentation
- publication with immutable version snapshots
- branded consumer-facing rendering
- mobile-first responsive presentation
- integration with the resolver for scan-based access
- custom domain support for passport URLs
Some related capabilities — such as consumer action workflows, digital wallet integration, and per-product theme assignment — are planned for future releases and are not part of the current live feature set.
