An olfactory sticker used in chats between electronic devices to make messaging more immersive, personalized, and authentic by integrating olfactory information with traditional text-based formats and AR messaging. Olfactory stickers are used to indicate to a recipient that a message includes olfactory information. The olfactory sticker illustrates a graphical representation of a particular scent that can be sent and received via a chat or an AR message. Olfactory stickers provide the recipient control of accessing the transmitted scent at a desired time. This is particularly useful since certain olfactory information, i.e., scents, can be very direct and intrusive. Olfactory stickers are activated (i.e., release their scent) when they are tapped or rubbed by the recipient.
