Don't expect to find these Viva Piñata cards in stores; this guy above is just a mockup, made specially for the folks at Microsoft's Spring Showcase yesterday. Hold it up to the camera and Viva Piñata: Trouble in Paradise will process that barcode on the right side, plopping the character into your game.
The feature, while impressive (and early), was temperamental in our demo; however, when working correctly, it will let users share their piñatas by creating a card through the game's website. The camera is surface agnostic so you can print the card out, or stick the image on a forum, save it on your iPod, or just email it to your entire address book (that always goes over well). Check out a shot of the process in action after the break.
