CARD IDENTIFICATION Ace automatically identifies your card by reading the card number and matching it against a catalog of One Piece TCG cards. It even distinguishes between regular art, alternate art, and parallel variants using visual comparison. REFERENCE COMPARISON When your card is identified, Ace fetches a pristine reference image and uses it as a baseline during grading — the same way a professional grader would compare against a known standard.
