Abstract
Using radio frequency technique, the reader machine will load call signal into 70MHz radio frequency, and send to response machine wirelessly. The call signal will be sent to the control of response machine by circuit coupling, demodulation, voltage comparator. The control will analyze and identify the call signal, send the stored 4-bit binary code back to the reader machine by transmitting modulation circuit, and display the detail of response machine.
