    Hmm, the RFID system which I helped to develop a few years ago
    used 5-cent tags operating in the 2.4 GHz area.  It was a bit
    faster than the low-frequency systems, too; read speed was about
    a thousand tags per second in the best case, and a cart
    containing a few-hundred tagged items could easily be read in the
    time it took to pass it through a doorway.
