Bluetooth is a wireless protocol that is good for "about" 30
feet typical. I would recommend checking out www.bluetooth.org
or www.bluetooth.com . The .com is for more general info while
the .org is for "SIG" members. At the .com site you can download the
Bluetooth specifications. Bluetooth is in the frequency of 2.45GHz
industrial-scientific-medical (ISM) band. There are alot of companies that
manufacture or are in the process of manufacturing Bluetooth devices.

National ( www.nsc.com )
ATMEL ( www.atmel.com )
RF Micro Devices ( www.rfmd.com )
Philips ( www.philips.com )

And the list goes on and on!!!

I don't know enough about the stamp to comment on it's use I'm afraid.

Best of luck!!!
