You’ll have to mod the template ‘card.php` file to changing the cropping method.

Change this:

$entry->getImage( array(
        'image'    => $atts['image'],
        'height'   => 120,
        'width'    => 100,
        'fallback' => array(
                'type'     => $atts['image_fallback'],
                'string'   => $atts['str_image']
                )
        )
);

To this:

$entry->getImage( array(
        'image'    => $atts['image'],
        'height'   => 120,
        'width'    => 100,
        'zc'       => 1,
        'fallback' => array(
                'type'     => $atts['image_fallback'],
                'string'   => $atts['str_image']
                )
        )
);

Here are the valid values; 1 is the default method:
0 Resize to Fit specified dimensions (no cropping)
1 Crop and resize to best fit the dimensions (default behaviour)
2 Resize proportionally to fit entire image into specified dimensions, and add borders if required
3 Resize proportionally adjusting size of scaled image so there are no borders gaps

Hope that helps!
