A reader sent me a link to a video interview with Tim O'Reilly, founder of
O'Reilly Media, in which he states: "I think that RFID is an evolutionary dead end, and the reason I think so is the reason why we don't wear name tags all the time. You think about this conference. People have name tags because they have to be identified so they can get into sessions... but that's not in everyday life. If we meet again, I won't recognize you because you are wearing a name tag. I'll recognize you because I've seen you before. Our machines are getting like that. Semantic Web or RFID is things wearing name tags, and Web 2.0 is learning to recognize things by accumulating context... We're getting to that kind of augmented reality, where our computers will have senses that are as good as ours or better... they are going to recognize faces, they are going to recognize objects, they are going to have immediate recall." (See
Tim O'Reilly on Recognition, RFID and Web 3.0.)
I don't know O'Reilly personally. I know he's very successful and well-respected, but I think, frankly, he needs to get out from behind his Web 2.0 computer and step into the real world. He also needs to think through his opinions a little more deeply. His own argument against RFID proves the case for it.
O'Reilly claims we don't wear name tags in everyday life, and that's why we don't need RFID. In reality, however, we
do wear name tags every time we are faced with an unfamiliar situation in life—when, for instance, we visit our kids' teachers at school, go to a conference, or enter a building where we don't work. We also drive around every day in cars containing license plates that allow us to be identified.
The reason is that as good as human senses are, they can't identify what they don't know. One of the big things RFID does is enable computers to identify things they've never seen before—so, for example, a customs agent can identify a new product you're sending to a new customer.
Another problem with O'Reilly's argument is that as good as human senses are, they can't easily distinguish between different objects that look identical. One reason food companies are turning to RFID is that the technology can quickly tell workers which of three identical containers holds the sugar or flour that's been sitting in storage the longest. And apparel companies are turning to RFID because it can help a salesperson identify a medium-size shirt that has been placed on a shelf with large shirts.
It's hard to believe computers are going to get so sophisticated that they will be able to point a camera at a shelf of red polo shirts and distinguish the medium-size shirts from the large ones—or know which corrugate box of soup goes to
Wal-Mart and which to
Albertson's, or which plastic container of sugar is the oldest and should, therefore, be used first.
Another issue has to do with the limits of some types of senses. We can view and recognize objects with great sophistication, but we can't see into boxes, and neither can a computer equipped with a camera. An RFID system, however,
can identify items within a box, which happens to be an extremely useful ability in the supply chain.
RFID systems are sensory systems that enable computers to monitor products, assets or the environment on a large scale. A single computer, for instance, could be connected to an RFID network and monitor hundreds of shelves in a warehouse or store. That seems far more cost-effective than deploying computers everywhere to monitor the shelves with cameras and other sensors.
I do agree with O'Reilly's view that we are moving away from a world in which people look at reports from computers and make decisions, to one in which computers make decisions and people continually improve the algorithms the machines use to make better decisions. But I think what O'Reilly is missing is that RFID is one very critical type of sensor for a computer, and that a computer's sensors will not necessarily be modeled on our own. We can recognize people through facial recognition, and so can a computer. But that doesn't mean a computer can't recognize objects by reading a serial number on an RFID tag. Computers will naturally have sensors we don't, and those sensors can be networked to cover large areas cost-effectively.
Call it Computer 2.0.

RFID : A HISTORIC CHANCE
THE RFID SOLUTIONS CAN CHANGE THE WORLD. BUT THE DISADVANTAGE RELIES ON THE PERSONALITIES WHO WILL TAKE CONTROL OF THE WHOLE SYSTEM. A SOCIETY WHERE EVERYBODY HAS HIS RFID NUMBER WILL BE A SOCIETY OF GEORGE ORWELL' S 1984. ANYWAY TECHNOLOGY CAN NOT BE STOPPED.

Counterpoint
Actually, one of the safeguards to consumer privacy is that no one will control the system, just as no one person or group controls the Internet. There were many fears that the Internet would lead to privacy invasion and control by companies, yet the Internet has become the greatest democratizing force the world has ever seen. Any abuses of RFID technology will be posted on the Internet anonymously in minutes. I also disagree that technology cannot be stopped. From what I understand, it's been stopped pretty thoroughly in North Korea.

Re: Counterpoint -- Stopping technology
Mark, I would suggest that N Korea has not 'stopped' technology. At best, they have simply delayed its application into the general society. Rumor is that Kim and his menions all have excellent access to the Internet. Indeed, it is difficult to have successful[!?] nuclear and rocket programs without access to the latest technology. The fact that their educational system and technical skills may not yet be quite up to the level they need to be does not mean they have in any way 'stopped' technology. Had they truly been trying to stop technology, their miolitary would be fighting with sharpened sticks and throwing rocks. Hardly the case from what I read. And FWIW, I'm not too concerned about individuals and general corporations controlling the Internet. I am concerned about gevernments and certain telecommunications companies controlling it. And if you think that CAN'T happen, I have this swampland in Florida you might be interested in..... ;-)

Information Control
We inadvertantly wear and use 'name tags' everyday; drivers licenses, ATM cards, Airmiles, internet logins, credit cards. The list goes on. In each instance, it acts as an identifier. RFID will make access to the same information quicker and more accurate.

Touche
I think rulers having access to technology and not providing it to their people is the equivalent of stopping technology, but we can argue semantics. The larger point is that in a democratic capitalist society, technology serve the people be people have the money. The government cannot control the Internet or RFID. The government can abuse the technology, even on a large scale, as we have seen. But the Internet is used by people to get information out about government abuses and individual misdeeds far more than it is used to spy on people. RFID similarly will be used by people to get information about the products they buy far more than it will be used by the government to track how many boxes of Cheerios you buy.
