vCard, also known as VCF (Virtual Contact File), is a file format standard for electronic business cards. vCards can be attached to e-mail messages, sent via Multimedia Messaging Service (MMS), on the World Wide Web, instant messaging, NFC or through QR code. They can contain name and address information, phone numbers, e-mail addresses, URLs, logos, photographs, and audio clips.
vCard is used as a data interchange format in smartphone contacts, personal digital assistants (PDAs), personal information managers (PIMs) and customer relationship management systems (CRMs). To accomplish these data interchange applications, other "vCard variants" have been used and proposed as "variant standards", each for its specific niche: XML representation, JSON representation, or web pages.
The standard Internet media type (MIME type) for a vCard has varied with each version of the specification.
vCards can be embedded in web pages.
RDFa with the vCard Ontology can be used in HTML and various XML-family languages, e.g. SVG, MathML.
jCard, "The JSON Format for vCard" is a standard proposal of 2014 in RFC 7095. This proposal has not yet become a widely used standard. The RFC 7095 does not use real JSON objects, but rather uses arrays of sequence-dependent tag–value pairs (like an XML file).
hCard is a microformat that allows a vCard to be embedded inside an HTML page. It makes use of CSS class names to identify each vCard property. Normal HTML markup and CSS styling can be used alongside the hCard class names without affecting the webpage's ability to be parsed by a hCard parser. h-card is the microformats2 update to hCard.
MeCard is a variation of vCard made by NTT DoCoMo for smartphones using QR codes. It uses a very similar syntax, but in a more consolidated way as the storage space on QR codes is limited. It's also limited in the amount of data that can be stored, not just by the standard but the size of QR codes.
An example of a simple vCard (from RFC 6350 of August, 2011, abbreviated):
BEGIN:VCARD VERSION:4.0 FN:Simon Perreault N:Perreault;Simon;;;ing. jr,M.Sc. BDAY:--0203 GENDER:M EMAIL;TYPE=work:simon.perreault@viagenie.ca END:VCARD
This is the vCard for "Simon Perreault" (the author of RFC 6350), with his birthday (omitting the year), email address and gender.
vCard defines the following property types.
All vCards begin with BEGIN:VCARD
and end with END:VCARD
. All vCards must contain the VERSION
property, which specifies the vCard version. VERSION
must come immediately after BEGIN
, except in the vCard 2.1 and 3.0 standards, which allows it to be anywhere in the vCard. Otherwise, properties can be defined in any order.
