An ID Number for Everything

Actually, having a unique bar code could be very beneficial when recovering lost and stolen property. If everything is uniquely identified, and you have somehow recorded your id codes for certain things that are of some value (either real value or sentimental), this could potentially aid in goods recovery. Granted, it could be taken to absurd extremes, but for more important items (artwork, computers, rare books, etc), this could be invaluable.
Be excellent to each other. And... PARTY ON, DUDES!
Why not just give every item an IPv6 address? Assign the UCC a /16 for merchandise and you've got 2^112 == 5e33 possible codes. The IPv6 folks are going on and on about giving everything an IP address--wouldn't this be a perfect application?
There will be a huge fight against these in terms of the privacy issues -- tracking cars, for example.
Yeah, imagine how awful it would be if every car had a unique identifier associated with it. You could be identified wherever you go by anyone with access to the right equipment.
Ever heard of a license plate?

"No more inventory counts. No more lost or misdirected shipments. No more guessing how much material is in the supply chain--or how much product is on the store shelves."
Wrong. Completely wrong. If you have ever worked for a major retailer, you will come to understand this reality.
ID's are not a panacea. You have to have a system of control and accountability over your inventory that makes use of a unique ID and checks itself constantly, forcing correction.
You'll always have a need to do a physical audit.
Thank heavens you aren't allocating bit-space then. Part of the power of what you think are excessively large address spaces comes from the fact that they stay sparsely populated (and the resultant ease with which you can perform classifications due to that sparseness).
Example: IIRC there are less than 256 countries in the world. One possible IPv6 allocation is an 8-bit country code field embedded in the 128-bit address, leaving 120 bits for each country to address devices. And then in the US, for instance: 6 bits for the state field, 8 bits for the county field, 8 bits for the city field, still leaving 98 bits for addressing *per city*. A similar example holds for 96-bit barcodes.
The article is pretty confusing. This is not a barcode at all: it is just setting up the number space that will be used for RFID tags. All that has been decided, AFAICS, is that it will be a 96 bit code in the RFID chip, MIT will hold the central registgry, and many interested manufacturers are meeting to agree on how to divide up and administer that 96 bit space.
Bit of a "Duh" if you ask me. Of course it has to be done, but this is pure implementation territory: it doiesn't affect the privacy issues on bit.
Mind you, I do wonder what the delta cost on the RFID chip of moving from 96 bit to (say) 128 bit - or even 256-bit. While I agree that these things are going to be produced in trillions and therefore millionths of a cent add up, I would have thought that most of the cost was constant per unit - slicing, packaging, testing etc.
Consciousness is an illusion caused by an excess of self consciousness.
But what happens when Quebec, British Columbia, the Yukon and Newfoundland & Labrador leave Canada, Scotland and Wales break away from England, more Balkan regions declare their independance, the Spanish regions break Spain into four, Iraq gets partitioned, and Texas secedes from the USA? Is 256 always going to be enough for all the countries?
