Scratch and sniff
Scratch and sniff technology generally refers to stickers or items that have been treated with a fragrant coating. When scratched, the coating releases an odor that is normally related to the image displayed under the coating. The technology has been used on a variety of surfaces from stickers to compact discs. 3M invented the technology in 1965, using a process originally developed for carbonless copy paper called microencapsulation.
