Hi Bruce,

Yes the system you described is very easy to build, the expensive part is
the pick up head, indala <sp> corp in the USA makes these panels that are
about 3 foot high, 1 foot wide and an inch thick, they have a range of ~18
feet when they are mounted with no ferrous materials around. I used to use
these in carparks, the only problem is to activate the card you need to hold
the card to get the ground plane (the human body acts as the ground plane)

IIRC the readers and the smart electronics are around AU$300 a pair, and the
output is in the industry standard Wigand :o)

Regards,

Kat.
