Abstract
A touch control device includes a touch area, a border area, a inductive coil, a proximity sensing unit, a near field communication unit, and a switch module. The touch area is for sensing touch input. The border area is located at periphery of the touch area. The inductive coil is located on the border area. The proximity sensing unit is for transmitting a driving signal to the inductive coil when being coupled to a first end of the inductive coil, and determining whether the inductive coil is close to an object according to a sensing signal generated by the inductive coil. The near field communication unit is for performing near field communication when being coupled to the first end and a second end of the inductive coil. The switch module is for controlling coupling statuses of the proximity sensing unit and the near field communication unit to the inductive coil.
