A vCard contains personal information, such as postal addresses, public security certificates, email addresses, and web sites. The vCard specification makes it possible for different computer programs to exchange personal contact information; for example, a vCard can be attached to an email or sent over a wireless connection.

The standard vCard format is a text file with properties in name:value format. However, there are multiple versions of this format as well as compatible alternatives in XML and HTML formats. This class library aims to accomodate these variations but be aware some some formats do not support all possible properties.
