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!
