  3. 03

    Authentication

    Materials, printing and known card characteristics are reviewed.

  4. 04

    AI-Assisted Analysis

    Computer vision assists with centering, corners, edges and surface inspection.

  5. 05

    Human Review

    A trained grader reviews all collected observations.
