How it works

Scan the card. Keep the right print.

GrandFolio reads the card code, checks the visual version on-device, and asks for confirmation whenever the result should not be guessed.

  1. 01

    Frame the card

    Point the camera at a card. GrandFolio reads the printed code and narrows the exact version.

  2. 02

    Confirm the print

    When artwork or finish is uncertain, choose from clear candidates instead of accepting a silent mistake.

  3. 03

    Add it to the log

    Set quantity and condition, then watch collection value and set progress update.
