Point the camera at a fingerprint QR — or paste a fingerprint — and the permanent identity resolves from ptpge.org. The mark on the print should match the mark shown here.
Permanent identifiers live on the neutral PTPGE namespace. The mark is drawn from the fingerprint itself (ptpge-mark/3) — it can be recognised and verified, never decoded; the QR carries the data. Nothing you scan leaves your device except the lookup of the fingerprint itself. · Scan v0.7.0
