Abstract
A dermatoglyph identification apparatus and an identifying method thereof are provided. The dermatoglyph identification apparatus includes a switch circuit, a signal source and a plurality of sensors. The signal source is selectively connected to the sensors through an impedance element. The switch circuit switches at least one sensor to be connected to the impedance element, and switches rest of the sensors to be connected to a ground terminal of the signal source. The dermatoglyph identification apparatus identifies dermatoglyph according to a sensing signal generated by the sensor connected to the impedance element in response to a reference signal of the signal source.
