What is that “vCard” section below the signature section?
A vCard is a special email attachment containing your contact information. When you send email containing a vCard, some email programs (such as Microsoft Outlook) can read it and automatically add your contact information to the recipient’s address book. People who don’t use a program that can read vCards, however, will just see an attachment. We recommend not using vCards unless you specifically know that most of the people you send to can read them; in today’s virus-riddled Internet, it probably isn’t a good idea to send an attachment with every email.
