A custom field of special interest is notes. You can add or edit notes quickly and easily to cards, before or after scanning. You can also add text recognized on a card to notes: to do that, in the card text details view you see after scanning, touch a text item then its type and chose “Add To Notes”. Note: cards with notes show a yellow post-it icon in the cards list view. Touching that icon is a shortcut to open the notes to view/edit without needing to open the card itself.
