Harry Potter Contact Cards is a collectible trading card set published by Panini in the United Kingdom in 2018, licensed from the Harry Potter film franchise. The collection contains 140 numbered cards (with a companion limited-edition subset) featuring characters and imagery drawn from the Warner Bros. film series. The distinguishing mechanic of Contact Cards is a matching-icon system printed on the four edges of each card: players can connect two cards to see whether their edge icons align (a simple match), super-connect them for a higher-value match, or play various speed and domino-style mini-games using the icon patterns. Each foil-fronted packet contains eight cards. Panini subsequently released a follow-up product called Harry Potter Together Contact Trading Cards, extending the format with up to 200 cards including rare metal parallel variants. The original 2018 Contact Cards set is no longer in print. As a proprietary-play collectible product rather than a structured competitive game, it fits the PCG classification: a trading set designed primarily for swapping and casual play rather than tournament deck construction.
