Batteries
Source recorded. The supplier’s wording was not captured in this research record.
Note: From the register's identity research. That sweep recorded the source and the date but did not capture the sentence, so no quotation is shown rather than one being invented.
QR code
“Every published product gets a public URL and a QR code for download as PNG or SVG.”
Public API
“Existing product data comes in by CSV upload or REST API.”
Audit trail
“That is the change history of the passport data, kept as an audit trail.”
Data export and portability
“The data export now follows version 2.0.1 of the BatteryPass-Ready standard, verified for all five battery categories.”

Passport updates and versioning
“Every passport is signed, a public verify endpoint recomputes hash and signature live, and changes go through versioning.”

This profile reflects what yellow3 lab could establish from public sources, topic by topic, with the source and date of every statement. A missing topic is not a finding about the company. Discuss your requirements directly with DPP HERO.
A company-supplied introduction, logo, contact link or sector list is published as the company wrote it. Research statements are what a supplier says in public, recorded with the source and the date yellow3 lab read them; yellow3 lab does not test them.
For your first conversation
Questions you can take to any Digital Product Passport platform provider. These are general prompts, not statements about DPP HERO.
Describe what you make and where you sell it. Ask which product groups and regulations the supplier supports today, and which are planned.
Ask how product data comes in from the systems you already use, how passports are published and kept up to date, and who maintains each part.
Ask what product data, identifiers and supplier information would make a first demonstration useful for your own products.
