Moo cards

Increasingly popular at Web 2.0-type gatherings, Moo cards are less than half the size of conventional cards and sport personalized photos on the back. They're sold in sets of 100 cards and users can upload as many as 100 images onto them.

Moo.com is partnering with services like Flickr and Second Life and allowing their users to upload pictures directly onto cards.
