Adding vcard to Contact Form emails in Wordpress?

Does anyone know of a contact form plugin for WordPress, or at least a way to implement a contact form on a Wordpress-based website, which includes a .vcf file (vcard) with the email that the contact form sends? I want the form to include name, email, and phone number with the message. Pretty basic stuff.

So how can we get that information included in a vcard that can be imported into an address book when the email comes in from the contact form? I'm utilizing Contact Form 7 as a plugin on the site.

Anybody know anything like that? Thanks!
