Touch-screen terminal and method and system for near-field communication

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