vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web or instant messaging. VCard is a file format standard for electronic business cards. The use of the comma as a field separator is the source of the name for this file format. Each record consists of one or more fields, separated by commas. In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text.
