The End of the Bar Code 468
valdean writes "The University of Wisconsin RFID Lab, principally funded by a dozen Wal-mart suppliers including 3M, Kraft Foods, and S.C. Johnson & Son, believes that RFID could spell the end of the ubiquitous bar code. The big draw? Speeding up supply-chain management. Wal-mart's warehouse conveyor belts presently move products at 600 feet per minute... but they want to be faster. And better informed."

When the post office first started using letter sorters, there were those times when the system glitched and a letter clogged the sorter path. After a few hundred letters piled onto the stack, the sorter stopped.
Now consider a conveyer moving at 1200 feet per minute. If one package redirector misses, the system will have to stop for manual intervention. So how fast can the conveyer be stopped to avoid slipping and pile-up of other packages. Then how long will it take to un-pile those items that were moving at 1200 fpm and get the conveyer started again. It's like taking a trip. If you have to stop for gas and rest-room, the average trip speed is greatly reduced.
How does Wal-mart plan to get packages onto the conveyer at that rate? It will take twice as many people and twice the number of conveyer entry points and exit points. Then they will have to double the number of people doing the final stocking to shelves or taking to trucks. Also the number of trucks entering and leaving the warehouse will have to double and the roads will have to handle the increased traffic.
RFID speeds things all along the route and will allow much faster distribution, especially perishables like fruit and vegetables, and that also translates to less refridgeration time and lower cost in keeping environments cool or hot or in special gasses to control ripening rate.
Now consider what happens at the high speed checkout when one of the items registers as alcohol and the buyer is less than proper age. The line manager will be over helping at the cashierless line since the stupid system stops because the weight is not what it expected, and if you think Wal-mart is going to add another line manager just so you can get through faster...!
One of my fears is that with the new handling speed the bananas will be too green to eat and I will have to buy them two days early.

The RFID broadcasts a signal, is up to the operator (or the receiver) to decode the signal and pick the important part of the message.
I know some RFID implementations in the food supply. Each different operator needs differen type of informations (the producer needs warehouse informations, the distributor needs the destination address, the customer needs expiry date and storage conditions). All these info can be stored on a single RFID. Each element of the chain can catch the signal and get his info.

Standards -- For one thing, there are many different standards (the US & Europe, for example, use different frequencies). Increased globalization of supply chains will make this a royal PITA, and probably not cost-effective, for many retailers.
RFID signals are easily blocked -- often accidentally. Soda Cans, for example, can interfere with RFID to such an extent that only tags on the outside of a pallet will be read.
Developing technology -- as RFID tech becomes more advanced, new capabilities will be put into play, and a lot of these may require software and hardware upgrades both for the tags and the readers. This, of course, can be expensive.
Unreliability -- while bar codes are relatively exensive to use (since they require active scanning within line-of-sight), they are very accurate. RFID tags have a misidentification rate that is higher, and can be compounded by improper placement of the scanned goods, or many other causes (like cell phone and walkie-talkie usage).
IMO, bar codes will be around for a very long while. Sure, Walmart will use RFID for supply-chain management. But, the real reason they are implementing it is:
RFID can be used to track consumers inside a store.
Better product placement, better loss prevention, better tracking of purchases.
Only the plus side, RFID is blocked by tinfoil hats.

It's further up the supply chain when you've got a pallet with maybe 50 cases on it. Barcode doesn't work very well because:
1. You have to trust the person creating the pallet's barcode. There is no incentive for walmart to pay an employee more for that trust, so they want a computer instead.
2. The 50 case pallet needs RFID to accurately report what's on the pallet. If a case or two might "fall off" a barcoded pallet then the barcode is none the wiser. In theory RFID would report the entire contents of the pallet as it's passing through the door.
The problems:
A. Cost. Barcodes got RFID beat hands down.
B. Accuracy. An RFID chip can't communicate through many layers of cardboard/product/cardboard so a pallet with boxes on the inside bottom do not get reported. If you want to be a millionaire, patent an amplifier/antenna that can be sprayed onto a paper tube and dropped down the center of a pallet of goods to get those inside boxes to accurately report.
