How SlabOwner works

SlabOwner is like a title record for graded cards. Each PSA cert has at most one verified owner. We vouch that a verified person held a specific slab on a specific date. Whether the card is genuine is the grader's and the marketplace's call.

Registering a card

1. Sign up with your phone number and pass a one-time ID check.
2. Type the cert number, card name, set and grade from the label.
3. Write a one-time code on paper, place it touching the slab, and take a live front and back photo.
4. We review the claim by hand and publish the card page.

Transferring a card

The seller shows a QR code. The buyer scans it, confirms their phone number, and taps Accept. The record moves instantly. Buyers can do the ID check later; until then their page says their identity is not yet checked.

What we never do

• Call a card authentic, real, genuine or guaranteed.
• Show your legal name, phone or email to anyone.
• Edit the ownership record. It is only ever added to.
• Touch cards. Software only.
