Stuart,
Funny you should mention the RFID tags - they
were
what I was really after from them, and they work a treat. I bought the
simple
RS232 RFID reader and 10 key fobs. The reader simply transmits the ID of
the tag
to the serial port of a PC when it detects a fob (and blinks an LED).
Range
of detection with the supplied aerial is about 20mm.
Ironically I need the RFID reader to output
TTL
RS232 and the barcode reader to do 12v RS232, but sods law means they're
the
other way around. If you find 9 other orders for the barcode scanner
*and*
a way of simply converting the levels up to 12v, then count me in as the
10th
order.

scanners
Ray,
I notice that there is a discount as
follows
Number
1 10+
100+
Cost £
20 12.45
6.10
If anyone is interested then
perhap a bulk buy is in order that I'm
willing to handle, costs above
exclude VAT
There are a few other item of interest, like RFID tags,
perhaps a
solution to the room occupancy problem ?
Have a browse
of
the website.
As ever I have no interest in this company other than as a
customer, any
e-mail relating to a bulk buy should be sent off
list.
Regards
Stuart

it
in to my PCs RS232 port? Anyone care to venture the odds on it still being
alive? Oops.
