A vCard is an electronic business or personal card and also the name of an industry specification for the kind of communication exchange that is done on business or personal cards. You may have seen a vCard attached to an email note someone has sent you.
Information contained on vCards typically includes personal data about the individual -- e.g., contact information, phone number, email -- plus other relevant data, such as Social Security number or health data, if the sender desires it. Figure 1 depicts a typical vCard.
Because a vCard is a published industry specification, software application developers can create programs that process vCards by letting recipients view them, or users can drag and drop them to an address book or some other application. vCards can include images and audio clips, as well as text.
A vCard, which is saved in the Variant Call Format file format, was developed by a consortium founded by Apple, AT&T, IBM and Siemens, which turned the specification over to an industry group, the Internet Mail Consortium (IMC), in 1996. The vCard specification makes use of the "person" object defined by the International Telegraph and Telephone Consultative Committee (now the Telecommunication Standardization Sector) X.500 Series Recommendation for Directory Services and can be considered an extension of it. A vCard format contains a name, address information, date and time, and optionally photographs, company logos, sound clips and geopositioning information.
The vCard format is described in detail in Request for Comments 6350. It was developed by the Internet Engineering Task Force, approved by the Internet Engineering Steering Group and released in August 2011.
To open a vCard that someone has attached to an email, your email program needs to support vCards, although not all such programs do. However, if you have an online address book that supports vCards, you can move the vCard file to that program for viewing or for addition to that program's database. If you can't open a vCard you've received, remember that its information may be repeated elsewhere in the email. It's basically just a business card.
A familiar variant of vCards is the quick response (QR) code format, composed of a square image with a pattern of black squares on a white background. Each pattern is different, and when scanned by a smartphone, the QR code displays vCard information, as well as many different types of data, such as access codes for secure systems. Figure 2 depicts a QR code vCard image.
