The best way to exchange personal data is to use vCard which is file format standard, specifically electronic business cards. E-mail messages are frequently transmitted with attached to them vCards, vCards may be interchanged in other methods; the World Wide Web could be used for this purpose. They can comprise name and address data, telephone numbers, name of the company, URLs, logos, photographs, and even audio clips.
 The vCard or Versitcard was initially projected in 1995 by the Versit Consortium, which includeed Apple Computer, AT&T (later Lucent), IBM and Siemens. In December 1996 possession of the format was passed to the Internet Mail Consortium, a commerce alliance of corporations which expressed an interest in Internet e-mail.
vCard is escorted by an offered standard for interchanging data about coming business-related engagements called vCalendar since displaced by iCalendar; the Internet Mail Consortium has made an assertion that it "expects that all vCalendar implementators derive benefit of these innovative open standards and make their software consistent with both vCalendar 1.0 and iCalendar."
Version 2.1 of the vCard standard is generally maintained by e-mail customers. Version 3.0 of the vCard format is an IETF standards-track offer accommodated in RFCs 2425 and 2426. The widely applicable filename extension for vCards is .vcf.
The Microformats.org community has determined the hCard microformat, a 1:1 demonstration of vCard in semantic XHTML, and it is employed localized by web sites such as Flickr and Yahoo! There are technologies such as X2V, run by web services such as the Technorati Contacts Feed Service that mechanically transforms hCards to vCards thus supplying interoperability between hCards issued on the web, and the above-mentioned vCard customers.
The Jabber Software Foundation has determined an XML vCard format and it is applied with technique such as Jabber and Light-Weight Identity. An RDF-based vCard specification has been determined by W3C.
Transmitting vCards by Bluetooth is one of the most generally consistent but unrefined types of placecasting. Since transmitting vCards via Bluetooth does not call for appliance combination, some employ the standard to convey unnamed messages.
