Register with AI
Snap a photo of your graded card. Our AI reads the grader, grade and cert number and fills everything in for you.
Get QR & certificate
Each card instantly receives a dynamic QR code and a downloadable PDF ownership certificate.
Verify anywhere
Anyone can scan the QR or search the registry to confirm the card is genuine and who truly owns it.
Transfer ownership
Sold or gifted a card? Transfer it securely — the new owner accepts and the ownership history is preserved forever.
