It is possible, but you would have to edit the template in order to show the categories assigned to the entry.
You can add the categories to the
card-single.php files by adding this where you want them to be displayed:
$entry->getCategoryBlock( array( 'separator' => ', ', 'before' => '<span>', 'after' => '</span>' ) );
I recommend following the method in this QuickTip so you can add it in an update safe way.
Hope that helps!
