      This could be interesting, and the total logistics impact is staggering.

      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...!

It's great for business to have a liberal return policy, but there are tons of people that abuse that with trying to return stolen merchandise, etc. If retailers had RFID, they could save a lot of money, through lessening theft and LP training.

    RFID can be advantageous to suuply-chain and distribution management, but there are still several problems that need to be addressed before the bar code will die out.

    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.
