Might as well keep it on-list, then it's in the archives for future
reference. It will be fairly brief as there's not much to report.

This is my post of 12th Aug

"HI all, has anyone comments about the RFID systems from
the various manufacturers with respect to reliability, supply,
price etc ? I need to get a price for > 1M and any comments
listers have could be important. Apart from the larger micro
companies, are there any others I should be aware of ?

Also, any significant differences between the MHz and kHz
varieties. The application is expected to have about 0.5m
range. Although I've looked into RFID in the past, I haven't
actually used the chips (mainly because of the set-up costs),
so I've some idea of what they are capable of. Just looking
for practical advice"

The further information I wanted was regarding the serial
number, which is integral to chip as it leaves the factory.
For the application I'm researching I wanted to know if
the serial number is unique (it is) and so can be cross-
referenced to another unique number in a database. I
still haven't found an answer to the kHz vs MHz versions.
Quite P.O.ed actually. Tentative price from Atmel for their
basic RFID chip was US$0.48 at 2.8 million quantity as a
wafer suitable for credit card mounting. The REC agent in
Sydney was most approachable and helpful. I don't have
my notes handy, but the Atmel development system was
cheaper than the Microchip by 1:3 (NZ$960 vs $NZ2800)
