Photo-anchored provenance for every card you sell. Buyers scan, see the card you photographed, and trust the sale.
// No credit card required. 15 codes/month free.

Status: Verified
Authentic_Original
YOUR LISTING HAS PHOTOS.
BUT DOES THE BUYER
TRUST THEM?
No Proof
Your word is all they get
You photograph your card. You write the description. Buyers take your word for it.
Return Fraud
Scammers win by default
Scammer buys your card, returns a reprint, keeps the original. eBay sides with the buyer.
No Reputation
Your trust doesn't travel
Your eBay feedback says you're reliable. But it doesn't travel to TCGPlayer, Mercari, or card shows.
Slab gives every card a provenance page — photo, listing link, seller identity.
One scan, full trust chain.
THREE STEPS. FULL TRUST CHAIN.
No app required for buyers. No middlemen. Just proof.
Create
Snap a photo of the card. Paste your listing URL. Slab generates a provenance code in 2 seconds.
2 SECONDS
Ship
Print the code. Ship it with the card. The code links to your listing, your photo, your seller profile.
PRINT & SHIP
Verify
Buyer scans the code. Sees the provenance page: your photo, your listing, your trust history. Proof, not promises.

INSTANT
FOR EVERY WAY YOU SELL.
Marketplace Sellers
eBay, TCGPlayer, Mercari, Whatnot. Two taps and a photo — your listing gets a verifiable trust artifact.
Card Shops
Build your shop's trust brand. “Authenticated by [Your Shop]” on every provenance page.
Live Breaks
Code generated on-stream. Buyer receives it with the card. Provenance starts on camera.
Sealed Product
Label on the factory seal. If the seal is broken, the provenance chain records when it was originally applied.
FROM THE HOBBY.
Real problems from the hobby. Slab is built to solve them.
“I sell 50+ cards a week on eBay. If I could ship proof with every card, I'd win more disputes and close more sales.”
Card Shop Owner
Scenario, Local Game Store
“Last quarter I lost 3 return fraud cases because I had no way to prove what I actually shipped. Photos alone don't cut it.”
Power Seller
Scenario, eBay / TCGplayer
“We print limited-run chase cards. If each one shipped with a provenance code, buyers would trust the secondary market more.”

WITH SLAB vs. WITHOUT.
Every sale has a trust gap. Here's how Slab closes it.
WITHOUT SLAB
- x
Listing photos only
Buyers see your photos but have no way to verify you actually have the card.
- x
Feedback doesn't travel
Your eBay reputation means nothing on TCGPlayer, Mercari, or at card shows.
- x
No physical proof
Nothing connects the card in the buyer's hand to the listing they purchased from.
- x
Return fraud: your word vs. theirs
Scammer returns a different card. You have no evidence. Marketplace sides with the buyer.
WITH SLAB
- ✓
Photo-anchored provenance
Buyer scans the code, sees the photo you took at certification time. Visual proof, not promises.
- ✓
Seller profile travels everywhere
Your Slab trust history follows you across eBay, TCGPlayer, Mercari, shows, and direct sales.
- ✓
Physical code proves shipment
The code ships with the card. It links to the listing, the photo, and your identity.
- ✓
Scan the returned card as evidence
If the return doesn't match, the provenance page is your dispute evidence.
Slab doesn't replace your marketplace. It adds a trust layer on top of it.
Same platforms. Same workflow. Now with proof.
THE BUYER RETURNS
A DIFFERENT CARD.
YOU HAVE PROOF.
Scammer buys your card, returns a reprint, keeps the original, and gets an automatic refund. It happens every day on eBay.
With Slab, every card has a photo-anchored provenance page. If the returned card doesn't match the provenance photo, you have the evidence to win the dispute.
