deepidv Adds TCG Authentication, Verification, and Validation for Marketplaces
FOR IMMEDIATE RELEASE
SAN FRANCISCO, September 21, 2026 — deepidv, the AI-native identity verification engine and agentic compliance suite, today announced AI-powered trading card game (TCG) authentication for online marketplaces. The new capability verifies the human buyer and the human seller and validates the product they are trading, the card or the graded slab itself, in a single flow, closing the gap that has made high-value collectibles one of the most fraud-exposed categories in e-commerce.
Collectibles are now a multi-billion-dollar market. A 1999 first-edition Charizard graded gem mint has sold for six figures, a one-of-one Magic: The Gathering The One Ring changed hands privately for a reported seven figures, and graded sports cards clear enormous sums at auction houses such as Goldin and PWCC. Where the money went, the fraud followed: counterfeit cards, trimmed and doctored cards, forged autographs and patches, and reslabbed cases carrying fake grades now move through the same peer-to-peer channels as genuine grails, and the FTC and the FBI Internet Crime Complaint Center both track rising online-marketplace fraud losses.
One check, two answers
deepidv's TCG authentication answers two questions at once. First, who is on each side of the trade? deepidv verifies the buyer and the seller with document and biometric checks, structural liveness, and deepfake and AI-face detection, and its 1:N matching stops a banned seller from returning under a new name. Second, is the product real? deepidv's AI Detection analyzes images of the card and its slab for the signatures of counterfeiting, reprinting, trimming, and reslabbing, and cross-checks grading certificates against the graders' own records.
- Buyer and seller verification. Every party is bound to one real, verified identity before a high-value listing goes live or a payout is released, the same protection deepidv brings to peer-to-peer marketplaces.
- Card and slab authentication. AI Detection flags counterfeit, altered, and proxy cards and fake or swapped grading slabs from photographs, the fraud patterns detailed in the deepidv guide to counterfeit slabs and trading card fraud.
- Proof anyone can check. Every verification is sealed with tamper-evident cryptographic proof at proof.deepidv.com, so buyers, sellers, and platforms share one auditable record.
The capability spans the categories collectors actually trade: Pokemon cards, Yu-Gi-Oh cards, Magic: The Gathering cards, and sports cards from Panini and Topps, whether raw or graded by PSA, Beckett, CGC, or SGC, and whether they sell on eBay, TCGplayer, Whatnot, or Fanatics Collect.
Why marketplaces need both halves
"For years, verification and authentication were treated as separate problems. Marketplaces checked the person or the product, rarely both, and fraudsters lived in the seam," said Shawn-Marc Melo, Founder and CEO of deepidv. "A verified seller can still ship a counterfeit Charizard, and a genuine card means nothing if the person selling it is a banned account back under a new name. deepidv closes both gaps in one AI check, verify the buyer and the seller, validate the card, seal the proof, in under 150 milliseconds. That is how you make a stranger-to-stranger trade of a six-figure collectible feel as safe as its grade."
For marketplaces and collectors, the practical guides sit alongside the announcement: how to sell trading cards online safely, how to sell graded cards through consignment and escrow, and how deepidv verifies both sides on the marketplace trust layer and its wider verification platform.
