Whether RFID is changing industries isn't much of a question any more. There are still uncertainties are how about far its reach will extend and what technologies and implementations will eventually become standard.
Many of the RFID articles on this site may seem a bit outside the realm of industrial control, but we think they're important regardless of whether the topic fits into the traditional view of factory automation.
That's because when Wal Mart makes a move, it can impact many production lines. When the DoD expands its RFID usage, there's a fair chance it will help improve techniques for use in harsh environments. Any moves by these giants, or big companies like IBM, also help answer some of the uncertainties about technologies and adoption while also proving long term reliability.
Add in the pricing impact of Wal Mart volumes can also make a big impact on pricing, which is always a key element for adoption on the plant floor. Check out our Forum section if you'd like to see what others think about RFID.
