It looks like 3M, the company behind the Post-It note (you know, the one from Romy & Michele's High School Reunion) has been working with Evernote, the note-taking provider, to make sure that sticky notes continue to be used in this digital age we live in.
As of today, any photo taken with the new Post-it Note camera feature in Evernote for iOS 7 will digitize any Post-It Note in real life, and create a file that can be shared with anyone, anywhere. Captured Post-Its can also be categorized by color. So, for example, a green Post-It Note could be used as a homework reminder, while a yellow note could be a shopping list.
Captured notes are searched through the cloud-based platform, making it easier to keep track of your various notes.
