Correct me if I'm wrong, but doesn't RFID technology work similarly to sonar? The scanner sends out a certain frequency wavelength, the chip uses the wavelength as an energy source and sends back data for the scanner to interpret. So while the technology might not be here and easily accessable/affordable yet, wouldn't it be reasonable foresight to assume that the technology to scan a person's credit card from a distance of even a foot or so will be soon coming and completely undefended against?
