Use the result well
A clear answer, with the assumptions visible
These recommendations turn the result into an operational next step without hiding the inputs behind a score.
- 1
Replace the sample signing phrase and keep it private.
- 2
Test printed QRs, manual entry, camera access, and a backup device.
- 3

How this tool works

- Render each signed code as a local SVG QR with bwip-js.
- Embed only the valid signed codes in an offline check-in page with local checked-in state.
