Numbers like "2504 09 3987" also highlight transparency issues. Certification databases differ by jurisdiction in accessibility and clarity. When entries are opaque or when linking between hardware IDs, driver versions, and certification records is difficult, scrutiny weakens. That benefits neither the user seeking assurance nor the responsible manufacturer navigating cross-border compliance. The ideal is a system where a certification token resolves quickly to human-friendly details: device model, firmware/driver versions covered, test reports, and validity dates.
