Bokode: Imperceptible Visual Tags for Camera Based Interaction from a Distance
http://web.media.mit.edu/~ankit/bokode/

Could it be the next RFID+AR mashup? I can see it in pointer apps, tag a space etc.

"Current optical tags, such as barcodes, must be read within a short range and the codes occupy valuable physical space on products. We present a new low-cost optical design so that the tags can be shrunk to 3mm visible diameter, and unmodified ordinary cameras several meters away can be set up to decode the identity plus the relative distance and angle. The design exploits the bokeh effect of ordinary cameras lenses, which maps rays exiting from an out of focus scene point into a disk like blur on the camera sensor. This bokeh-code or Bokode is a barcode design with a simple lenslet over the pattern. We show that an off-the-shelf camera can capture Bokode features of 2.5 microns from a distance of over 4 meters."

A replacement for the black and white stripes of the traditional barcode is outlined by US researchers.

A replacement for the black and white stripes of the traditional barcode has been outlined by US researchers. Bokodes, as they are known, can hold thousands of times more information than their striped cousins and can be read by a standard mobile phone camera.

bocode project from MIT media lab. small code visible to cameras, but not human eye. Different info from different directions.

Just one club card - combine them all into one card.

There already are a few barcode related applications in the app store, but they all have one thing in common - they don't really work. Red Laser, which has just hit the iTunes App Store, is the ultimate iPhone barcode scanner, which works just like one of those red-laser scanners at the checkout (hence the name.)
