DPPera serves as a digital passport platform that is hosted for brands, importers, and manufacturers looking to comply with the EU's Ecodesign for Sustainable Products Regulation and the EU Battery Regulation. By entering product information just once, users can generate a passport page that is linked to either a QR code or an NFC tag, utilizing a GS1 Digital Link based on a GTIN or a DPPera-specific identifier. These passports are designed to be both human-readable and machine-readable, formatted as JSON with a GS1 linkset. The platform offers various features, including battery profiles with Annex XIII access levels, print-ready QR files, analytics for scans, a history of versions, the ability to import data via CSV, as well as a read API, and options for exporting in JSON, CSV, and ZIP formats. A permanent copy of the passport is stored upon publication, ensuring data integrity. DPPera accommodates a range of products such as batteries, textiles, and furniture, and is available in both English and Polish languages. Users can create two passports at no charge, while subscription plans begin at 119 zł per month, allowing for up to 50 active passports, making it a practical choice for businesses striving for sustainability. This comprehensive service not only aids compliance but also enhances product visibility in a competitive market.
