MIT's Bokode Bar Code

Another bar code post, thanks to StorefrontBacktalk -- MIT's Media Lab is readying the next technology that will try to challenge the barcode. It's a 3-millimeter optical tag called a "Bokode" that can store roughly a million times more data than today's typical barcode (at the same size) and claims some key advantages compared with RFID tags.

At a per-tag price of about $5 for the bokode, however, it will still need huge volumes to become practical.
