Abstract
A Near Field Communication (NFC) device for transmitting a signal, including an NFC transceiver circuit having a transmission terminal and a reception terminal connected to an antenna; an electronic signal damping circuit; and a controller configured to control the electronic signal damping circuit to dampen a signal at the reception terminal to have a lower impedance during a transmission mode of the NFC device, during which the NFC device transmits the signal by means of the antenna, as compared with during a reception mode of the NFC device.
