A VCF file is a standard file format for storing contact information for a person or business. It typically includes a name, address, phone number, e-mail address, and other contact information. VCF files also support custom fields, images, and other types of media.
VCF files are often used for importing and exporting contacts from address books. They may be attached to e-mail messages, which provides the recipient with an easy way to import the sender's contact information.
Windows users can open vCards using the included Windows Contacts program. Mac OS X users can open vCards with the included Contacts application. iPod and iPhone users can load vCards directly into the device's Contacts app. Android users can also load vCards using the Contacts app bundled with the operating system.
NOTE: vCards are saved in a text format, which means you can view the contents in a text editor. However, they may also include a block of binary data, which is often used to store a photo.
