A wireless multi-user touch control device including at least one input unit having a touch control input pad and a radio transmission element. A user can touch the touch control input pad to write characters or draft drawings thereon. The input unit serves to convert the characters and drawings into digital signals which are transmitted by the radio transmission element by way of radio frequency. The wireless multi-user touch control device further includes a receiving unit having a receiver, a mainframe and a display. The receiver responsively receives the radio signals transmitted from the input unit and input the radio signals to a processing unit of the mainframe for processing the signals. Thereafter, the display shows the characters or drawings identical to those written on the touch control input pad of the input unit by the user.
