Abstract: A hybrid communication device, an operation method thereof, and a communication system including the same are provided. The hybrid communication device includes a contact unit that includes an antenna for receiving a first communication signal and an electrode for receiving a second signal, a switch controller that includes a first switch and a second switch and controls the first switch and the second switch based on a change in capacitance of the electrode, and a signal processing unit that receives at least one of the first communication signal and the second communication signal from the contact unit via the first switch and processes the received signal. The first switch is connected to the contact unit, and the signal processing unit is connected to the first switch.
