Abstract
A touch-screen terminal, method and system for near-field communication are provided. The touch-screen terminal includes a touch sensor, the touch sensor includes multiple driver electrodes and inductive electrodes disposed on a substrate to form capacitor structures. At least one of the driver electrodes and the inductive electrodes is used as a transmitting electrode; at least another one of the driver electrodes and the inductive electrodes is used as a receiving electrode. In the present invention, signal transmitting and receiving are achieved by multiplexing the electrodes of the touch-screen terminals, thereby enabling electric-field-based NFC. The system part for signal processing is embedded in the chip and, therefore, there is no need for an additional inductive card reader or part with the similar function. The present invention does not change the original size of the touch-screen terminal.
