Three millimeters is about the size of an @ sign, and it’s also the size of the optical tagging technology developed by researchers at MIT—a technology that could replace the everyday barcode and much more. Bokodes refers to the light blur produced from an out-of-focus image, such as in a photograph. Turns out that heck of a lot of information can be programmed in that haze.
The bokode system can allow angle-encoded information to be read by an ordinary camera or even cell phone. And the little gadgets pack in a punch, being able to record far more information than a regular barcode.
What can this mean for small business?
Current protoypes feature a tiny LED-masked light source to emit the encoded information; however researchers are developing other ways to imprint the bokode stamp. One idea is to use a reflective method, such as holograms used in credit cards–which would also be cost-effective.
What makes bokode technology useful to retailers is that it would not require infrared (laser) light to be read, but instead could be viewed through with any flash and refracting lens, such as an out-of-focus handheld camera or even a camera phone.
