RFID Vs. Bar Code: RFID Is To Bar Code As Cellular Is To Phone Booth

There is no doubt that RFID will one day replace the barcode. The barcode will still exist, just like the phone booth, for the occasional need. The need for RFID today is not easy to understand, since today's version is much like the first cell phones, bulky and cumbersome, and "who is really going to use this?" Go several years into the future, where the RFID tag is a fraction of a cent (yes, just like every memory technology, the cost will 1/2 itself each year for the same memory size), and nearly every product that would make sense to include it has one attached or embedded. Take the cellular analogy and go RFID microreaders, where dock door portals and hand scanners are antiques. Picture every cubic inch of the superstore covered in the RFID read sweep. Aisles are embedded with inexpensive microreaders, and any product (tagged) can be inventoried real-time. Warehouses, supply trucks, freezers, storage areas, and checkout counters are all inventoried and instantaneous decisions are made. Would you run a tighter and more efficient business if you knew exactly how much product you needed to create, down to the single item level? Would you re-route a supply truck to a store with a higher out-of-stock level than an alternate store? If your product was placed on the wrong shelf, would it sell as well as it could have on the appropriate shelf? If this product was a featured sales item in a marketing campaign, but the item was not yet in some stores, would you advertise differently?
