Force file download for hCard & vCard Generator

I am using the hCard & vCard Generator and would like to know if there is a way to force the download of a vcard. Currently when I click the generate vcard button on my site link it opens up inline on the page. I realize that there are settings in browsers to show or download a file but since I cannot program other people’s browsers is there a way to force the download circumventing the browser settings?

Thanks
