Stickybits, a new iPhone and Android app that lets you scan any barcode and attach a geo-tagged message to that physical object, has been launched by Stickybits.

The barcode in a greeting card, for instance, could trigger a video message from the sender. One on a box of medical supplies could inventory what is inside. A business card with a code on it could link to a resume or LinkedIn profile.

The app lets you follow people and see their object stream, or get notified whenever one of your objects is scanned, moved, or new bits are attached to them.

Stickybits is similar to science-fiction author Bruce Sterling’s concept of “Spimes.”
