    I am preparing for a mobile, mid-range RFID project. It involves
    reading up to a dozen or so tags with a portable or hand held device
    in a range upto 2-3 meters. The data transmission doesn't have to be
    fast, but there may be more than one readable tag within reading zone.
    It would be nice if reading is not sensitive to the orientation of
    tags. The tags cannot be too big, and they may not always be in the
    line of sight. Finally, the system should as inexpensive as possible.
    We can do limited hardware and software work to integrate reader
    output (RS232 or USB or PCMCIA card)to a hand held pc. What technology
    (high/low frequency, active/passive) will work for such a system? What
    company/product/component do you recommand? What is the estimated cost
    (in US $)?
    Thank you very much!

    The SAVI system I referenced can read tags on trucks when they drive
    by sign posts on the highway.
