An identification system and method is disclosed to identify an identity and a position of a radio frequency (RF) device. The RF device generates a response signal when receiving an RF signal. The identification system includes a plurality of antenna units, a switching unit, an RF module and a microcontroller. Each antenna unit has a corresponding identifying area. The switching unit is coupled to the antenna units. The microcontroller controls the switching unit to select at least one antenna unit for transmitting the RF signal generated by the RF module, and determines whether the RF device positions in the corresponding identifying area of the select antenna unit according to whether the selected antenna unit receives the response signal. The microcontroller also identifies the identity of the RF device when the select antenna unit receives the response signal.
