Re:Intimate Walmart/RFID info (Score 1)

On the same principle, I work for a company that installs conveyor systems for major distribution centers. The biggest issue we see with RFID is too much visibility. When running a sortation system at 550 feet per minute and boxes 12 inches apart we could read 3 boxes at once and it becomes quite difficult to really differentiate the order of the boxes. The simple solution is multiple scanners but then we have issues with a no read on one scanner but a read on the next scanner. Simply put without an extremely refined field and improved response times RFID tags are not a viable identification system for high speed sortation systems.
