Abstract
An identification system, a physical apparatus, an identification apparatus, and an identification method of the physical apparatus are provided. The identification system includes the physical apparatus and the identification apparatus. The physical apparatus has a path circuit disposed to an identification detecting pin. The identification apparatus transmits a probe signal to the identification detecting pin and then receives a reflected signal, wherein the reflected signal is generated by the probe signal which responds to an impedance characteristic of the path circuit. The identification apparatus obtains identification information of the physical apparatus according to the impedance characteristic of the path circuit which is responded by the reflected signal. The identification system of the present invention can reduce the number of pin for identifying and effectively utilize the impedance characteristic of the physical apparatus to identify identification information.
