On the subject of RFID, I have a free subscription to the RFID
Journal. It comes as a weekly e-mail and discusses developements in
the RFID field. It is actually quite interesting. I think that their
web address is www.rfidjournal.com - You might want to check it out.
Lots of stuff seems to be going on with endless applications. Security
and inventory control seems to be just the beginning of the
possibilities. Like you, Bill, I think that there are still a number
of problems to work out but, if they can solve the size, power and
cost of the tags, I think that it will be all over the place before
long. As long as it is used basically for products, it should be fine.
However, whenever anyone mentions it for use in tracking prople within
a building for instance,then a gang of privacy issues surface.
