Export a Contact as a vCard
You can save a contact's information to a file by exporting that data as a vCard. You can use
this technique as a simple backup method for contact data, but it is most useful as an easy
way to send a contact's data to another person, as described in the previous section, “ Share
Your Contact Info . ”
You can export your own contact data or the contact data of another person. If you plan on
sharing another person's data, you should seek that person's permission before you do so.
