Barcode

QR codes are everywhere nowadays, but they don’t have to be. MIT scientists have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags into objects that can be viewed and tracked through an infrared camera.

Barcode stickers may provide valuable information on products, but they're rather unsightly, and they peel off over time. An experimental new alternative, however, is 3D-printed right into the item, and is invisible to the naked eye.

The GeniCan is a prototype device that attaches to a trashcan so it can be used to scan barcodes of items as they are thrown out. They can then be added to a list or automatically reordered.

The creators of the experimental Lumitrack motion-tracking system claim that it has much less lag time than existing systems, plus it's highly accurate and should be cheap to commercialize.
