a verifiable passport.
Import a real 3D scan, compute its 3DPass Grid2d fingerprint on this device, then anchor the evidence digest to Robinhood Chain.

Scan a real object
01
Scan the asset
Import an OBJ mesh from Files. Recognition runs on this device, and the mesh is never uploaded.
iPhone LiDAR ready
Scan the object with this iPhone
Walk slowly around every side. Green mesh shows what is captured. When you finish, the app creates the OBJ automatically and takes it straight to tagging — no Files export or re-upload.

How to create an OBJ scan on iPhone
- Scan the complete object with a LiDAR or photogrammetry app.
- Export a closed, detailed mesh as OBJ to Files.
- Choose that file above. Use the same scanner settings for rescans.
A camera photo is not a 3D mesh. Recognition starts only from captured or imported OBJ geometry.
02
Tag the asset
Name the object and add the claims that belong to it. Details stay on this phone — only deterministic digests can be anchored.

Review and anchor
Your passport is already saved on this device. Anchoring publishes only fixed-length digests and a resolver link.
What leaves this device
Passport ID, manifest digest, physical-claim digest, method digest, and public resolver URL. The OBJ, photo, serial, location, and notes remain local.

Encrypted backup health
This PWA stores passport records in this browser's IndexedDB. Download an encrypted export after important changes so a lost or cleared device does not erase your local record.
