"that's what i'm saying.. the RF chip is powered by the signal that's sent to it. higher power reader = higher powered RF = longer distance. it's of course limited though by how far the RF tag can transmit..."
True, but passive tags have practical read distances up to a few meters. Also, some newer chips have built-in firewalls and communication encryption. I agree, RFID in passports is a poor use of the technology, but it's here to stay I'm afraid.
Peace, UK
