According to article authors David Luckham and Mark Palmer, "It's not enough to use RFID as a "radio bar code." The savings from eliminating hand scanning of bar codes won’t pay for an enterprise-wide RFID system. Companies need to find ways to gather information they could not get with bar codes and analyze it in ways that make their businesses more efficient.
