vCard is a file format standard for personal data interchange, specifically electronic business cards. vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web. They can contain name and address information, phone numbers, URLs, logos, photographs, and even audio clips.

The vCard or Versitcard was originally proposed in 1995 by the Versit consortium, which consisted of Apple Computer, AT&T (later Lucent), IBM and Siemens. In December 1996 ownership of the format was handed over to the Internet Mail Consortium, a trade association for companies with an interest in Internet e-mail.

vCard is accompanied by a proposed standard for exchanging data about forthcoming appointments called vCalendar since superseded by iCalendar; the Internet Mail Consortium has issued a statement that it "hopes that all vCalendar developers take advantage of these new open standards and make their software compatible with both vCalendar 1.0 and iCalendar."

Version 2.1 of the vCard standard is widely supported by e-mail clients. Version 3.0 of the vCard format is an IETF standards-track proposal contained in RFC 2425 and RFC 2426. The commonly-used filename extension for vCards is .vcf.

The hCard microformat, a 1:1 representation of vCard in semantic XHTML, has been defined by the Microformats.org community and is in use by web sites such as Flickr and Yahoo! Local. There are technologies such as X2V, hosted by web services such as the Technorati Contacts Feed Service, that automatically convert hCards to vCards, thus providing interoperability between hCards published on the web, and the aforementioned vCard clients.

An XML vCard format has been defined by the Jabber Software Foundation and is in use with technologies such as Jabber and Light-Weight Identity. W3C has published an RDF-based encoding for vCard (see Representing vCard Objects in RDF/XML).

Sending vCards by bluetooth is one of the most broadly compatible but inelegant forms of placecasting. Since sending vCards via bluetooth does not require device pairing, some use the standard to transmit anonymous messages (see bluejacking).

Application have different implementations of the vCard standard. The Address Book on Mac OS X allows export of all contacts in one vcf file while Microsoft Outlook only accepts one contact per file.
