Photo-stickers are the latest fad among amateur photographers in Japan. Polaroid’s I-Zone camera has become a hot seller there, and was introduced to the U.S. at the September Motivation Show in Chicago. The pocket-sized instant camera takes mini-photos and turns them into stickers. (Rival Kodak has done well with sticker-photo booths in theme parks and some retail stores.) I-Zone can be branded and given away as a premium. Polaroid, Waltham, MA, launched nine other products at the show, including Pop Shots, the first-ever instant disposable camera; Joycam, an instant camera that takes pocket-sized photos; and pre-exposedfilm that carries a brand message on the photos.
