Part of the reason for so little RFID industry sector coverage by stock analysts is that while the technology has been around for decades, it is only recently that RFID has begun to get wide-scale interest from the business community. That's due mainly to RFID mandates by Wal-Mart, Tesco, and the US Department of Defense, which have forced companies to start adopting RFID technology.

Despite all the recent interest, in the opinion of some it still may be years before the RFID sector hits its stride for purposes of stock investing. See, for instance, this article in The Street.com.
