Open your Address Book, select a name and right click (or control-left click) to see the contextual menu that will pop into view. Choose “Export vCard” and save the vCard to your Desktop. You can send this file to anyone as an email attachment. Works on Macs and PCs. The recipient just imports the vCard into their own address book application. For Mac users, it’s as simple as double-clicking the vCard.
Want to send a few contact listings at the same time?
Make a Group. In your Address Book window, the leftmost column is the Group column. (If it’s not showing, click the leftmost button in the Address Book title bar.) Now click the plus sign at the bottom of the Group column, to add a Group. Call the Group something like “Share these”.
Now go to your Name column and command-click to select the listings you want to share. Drag the selections, all at once, onto the “Share these” group folder you just created in the left column. Now you can make the whole group into a vCard and share it with anyone. Same routine as for a single vCard… right-click on the “Share these” group and choose “Export Group vCard”. Save it to your Desktop and share it with anyone you like.
What if you want to share your vCards with another user on the same computer?
Just drag the vCard file to that user’s Drop Box. Here’s how to do that:
Double-click the Macintosh HD icon (upper right corner of your Desktop) to open a Finder window. Select Macintosh HD in the left column, then look to the right for a folder called Users. Open Users and click o the user name you wish to share the vCard with. Look inside that user’s Public Folder to find their Drop Box. Drop your vCard in there. The user will be able to retrieve it from their Drop Box, double-clicking it to enter it into their own Address Book.
