proofmark.art: artwork certificates of authenticity with NFC tags

proofmark.art helps verified creators issue digital certificates of authenticity for physical artworks, link them to secure NFC tags, and give collectors a public verification page.

How proofmark.art works

Register the work with photos, title, medium, year, dimensions, origin, and location.
Attach a proofmark.art NFC tag so collectors can tap or scan the physical artwork.
Share the public certificate page and monitor worldwide scan activity.

Public certificate and creator pages

Every certificate creates a clean public page for the work, with a path back to the verified creator profile and other available artworks.
