Explains the EU DPP Registry and the technical side: registration in the registry, identifiers, QR and data carriers, data formats (JSON, HTML, data models) and standards, and where passport data is kept. Each point carries the date of its source. For who owes, keeps or may hand off a passport, use scope_check. Use only what this tool returns: add no facts, dates or articles of your own, not even today's date. Keep every citation and the disclaimer line, and any "Planned, not law yet" or "being re-checked" label. Phrase answers about the product type, never as personal duties ("you must"). Never rank or recommend vendors. Never call this advice or yourself a consultant. If the result is not_covered, say so and point to the article given.
