QR verification
Verify a DeviceCheck report
Enter the public Report ID shown on a DeviceCheck report or PDF.
A valid public report shows its current verification state. Always use the live report or QR code when making a buying or selling decision.
How it works
From hardware scan to verifiable report.
The report remains useful after the scan because its signed payload can be checked independently against DeviceCheck.
02 · ASSESS
Evaluate condition and risk
Diagnostics feed the health, trust, risk, and coverage assessment while preserving unavailable measurements as unknown.
03 · VERIFY
Sign and share
The backend signs the canonical report. A public URL, QR code, and PDF let others verify the report without exposing private scan credentials.
Built for used-device transactions
One report, multiple trust decisions.
Buyers
Check the claimed hardware, current report state, assessment, diagnostics, and change indicators before purchasing a computer.
