A hands-free power tailgate system includes an antenna, a sensor, a first unit, a second unit, and a third unit. The antenna is configured to transfer a signal for authentication for a user to a smart key and receive an authentication code from the smart key. The sensor senses a movement in rear of the vehicle. The first unit receives the authentication code from the antenna to authenticate the user and outputs a sensor activation signal and authentication information when the authentication for the user is completed. The second unit activates the sensor according to the sensor activation signal, senses a movement of the user, and outputs movement information of the user. The third unit opens a tailgate using the authentication information from the first unit and the movement information from the second unit when the user moves according to a preset moving pattern. |
