I guess the reason we have QRs is because we are not yet there to determine what is the object in question. QR technology makes it easier by providing a unique tag for each object. So now when you see the QR code, your QR reader can access the look-up table to find what particular object it is.<p>The proposed technology is one step ahead of existing QR systems. But I guess the end goal to identify objects, and making a one to one association would be very cool. For Ex - when you want to identify people, you do not want them to come with QR code. Putting a name tag is something I will do to introduce myself in conferences so that people can recognize me from distance. But Ideally I would like that they recognize me by my face :)
