If there were any doubters out there, this week's newsletter contains ample evidence that radio frequency identification is rapidly becoming a key issue in materials handling. We report on two successful implementations, both in the United States, which demonstrate that the technology works, it's getting even better and it promises greater efficiency and visibility. And with growing adoption of the technology, there is increased pressure on forklift manufacturers to accommodate RFID devices in their vehicle design. Already, as we have reported, at least one major US retailer is demanding RFID tagging on all goods it sells, and it's only a matter of time before this becomes the norm. So the writing is on the wall and everyone in the supply chain needs to embrace the technology or be left behind by the competition.
