Early on, I had been following the RFID saga at Wal-Mart with some interest. I advised our mid-sized and small clients to take a "wait and see" attitude toward it. Now that things have shaken out a bit, it's interesting to look for updates on Wal-Mart's progress on Google.
Bottom line here is that in the past few months, there are many case studies on effective applications of RFID. There are also many case-studies (like Wal-Mart) where goals have been missed and missed again.
If you're thinking about RFID, make sure you've done your homework on ROI (return on investment) for the technology in your specific application. Spend some extra time in proof-of-concept as well.
