vCard is a file format standard for 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, e-mail addresses, URLs, logos, photographs, and even audio clips.
Versitcard was originally proposed in 1995 by the Versit Consortium, which consisted of Apple, AT&T Technologies (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vCard is accompanied by a proposed standard for exchanging data about forthcoming appointments called vCalendar, since superseded by iCalendar; the Internet Mail Consortium has issued a statement that it "hopes that all vCalendar developers take advantage of these new open standards and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 vCardDAV working group of the IETF is updating the vCard format. The commonly-used filename extension for vCards is vcf. In RFC 4770, vCard Extensions for Instant Messaging, a new type of entry to hold an IMPP URI is defined, which is "IMPP".
The hCard microformat, a 1:1 representation of vCard in semantic (X)HTML, allows publishers to embed vCard data in web pages. There are browser extensions such as Operator for Firefox; and there are technologies that convert such hCards into vCards, thus providing interoperability between hCards published on the web, and the aforementioned vCard clients.
An XML vCard format has been defined by the XMPP Standards Foundation and is in use with technologies such as XMPP and Light-Weight Identity. W3C has published a note on RDF-based encoding for vCard).
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).
Applications have different implementations of the vCard standard. The Address Book application in Mac OS X and the KDE Kontact application accept any number of contacts in a single vCard file and allow export of any set of contacts, or all contacts, in one vCard file, while Microsoft Outlook only accepts one contact per file. Google Contacts will import and export Mac OS X or similar vCard files.
The following is an example of a VCard file containing information for one person:
