A touch-control communication system includes a touch panel, a controller, a plurality of conductive contacts, and a switch control unit. The touch panel has a surface for detecting a plurality of touch points. The controller is electrically connected to the touch panel for receiving data corresponding to the plurality of touch points detected on the touch panel. The conductive contacts are placed on the surface of the touch panel. The switch control unit is electrically connected to the plurality of conductive contacts. The switch control unit performs a switch operation to configure every two of the plurality of conductive contacts to be electrically connected or disconnected, such that the touch panel detects different numbers of touch points corresponding to the plurality of conductive contacts for indicating a plurality of data states, thereby sending the plurality of data states to the controller.
