# Item-Level Digital Passports SealTrust Publishes Its Verifiable Product Passport Demo By Adam Harrie | Written with AI assistance | Published 2026-09-05 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/product-passport References: [packagingeurope](https://packagingeurope.com/news/sealtrust-publishes-digital-product-passport-anyone-can-verify/14643.article) & [sealtrust.io](https://sealtrust.io)  SealTrust published a live demonstration of an item-level digital product passport that lets readers verify product information in about 10 seconds using a [public blockchain anchor](https://www.trendhunter.com/trends/geamc). The passport can be accessed from a phone without requiring a dedicated app and is intended to let consumers, auditors and other stakeholders confirm that published records have not been altered. The system can include materials, components, suppliers, substances of concern and repairability data and exports information as JSON-LD using GS1 vocabulary. SealTrust also supports six access profiles for different users and can connect products through [GS1 Digital Link QR codes](https://www.trendhunter.com/trends/GS1-compliant-QR-codes) or [NTAG 424 DNA chips](https://www.trendhunter.com/trends/smartcask) for higher-value items. The NFC version can also record when packaging has been opened. For brands and consumers, the approach makes product data easier to verify independently while supporting traceability, repairability and circularity initiatives. It also demonstrates how public verification layers could strengthen trust in emerging digital product passport systems.
