Technical Details

To be honest I can't' quite see why it gets past the existing if (in_array('credit_card_type', array_keys($params))) { to cause this enotice but if (!empty($params['credit_card_type'])) { is also much more consistent with the style in our codebase and we would not want to try to resolve 'set but empty'
