Abstract: A touch-control communication system and a touch control communication method are provided in the present invention. The system includes a mobile device and a data transmission device. The mobile device has a capacitive touch panel, and the capacitive touch panel emits a touch sensing signal when the capacitive touch panel senses touch. The data transmission device is configured with a transceiver antenna and a signal inverting circuit. According to the transmission data, the data transmission device determines whether or not the signal inverting circuit outputs an inversion signal to the transceiver antenna, so that the capacitive touch panel obtains a logic state of the transmission data by detecting whether or not a touch point exists. Thus, the transmission data can be transmitted to the mobile device.
