This category includes 1 filed patent application, contributed by Wizards of the Coast.
The patent covers technology for authenticating trading cards at a set level, using physical properties of a card's substrate or ink as fingerprints to verify its identity. Wizards of the Coast describes a system that groups these fingerprints across an entire tournament deck or trade into a single authenticated set, with tournament history attached to the registration.
Wizards of the Coast filed 1 patent that takes a fundamentally different approach to verifying the authenticity of trading cards. Rather than authenticating each card in isolation, the application describes a method of scanning the physical properties of a card's substrate or ink, then bundling the resulting fingerprints from multiple cards into a single registered object set. This means an entire deck or a completed trade can be treated as one authenticated unit, with tournament history and related media content tied directly to that registration. The problem the patent addresses is that existing provenance records for individual collectibles often get associated with unrelated objects, making it impossible to verify that a group of cards belongs together as a set.
