I've been looking for a good article on RFID technology that explains the technology in plain term, yet doesn't degrade into meaningless euphoria. Found this article from BBC News recently. Read the whole thing.
The limits for the technology's application are set by your imagination - and the depth of your pockets.
"At the moment very few people have a good business case for RFID, because they don't know the costs involved, how the technology will develop and the extent of process engineering needed," says John Davison, head of retail research at consulting firm Gartner.
Honestly, its hard for me to watch the press about the development of this technology. Basically, what we're seeing here is the front-end of the roll-out, similar to the history of barcode scanners in the early late 70's to early 80's. Most articles within the industry have folks arguing passionately for or against RFID, while the general press is diabled with euphoria over what RFID will do for industry...without really understanding it.
