The Web has made people more social. But what about objects? That's the thinking behind Stickybits, a startup launched at SXSW that adds a social layer to barcodes. Using the company's Android or iPhone application, users can scan barcodes, attach a piece of information — either a video, note or audio recording — and receive a notification whenever someone else scans the same object. Stickybits also produces unique, one-off barcodes of its own that, when attached to a postcard, for example, add digital memory to static objects. The company sees the codes being used in everything from product reviews to including a digital copy of your resume on your business card.
