Near field communication device, method for operating a near field communication device, smart card and wearable

摘要

A near field communication device (400) is provided. The near-field communication device (400) can have an NFC transceiver circuit with a transmission connection (305) and a reception connection (307) for connecting an antenna (302), an electronic signal attenuation circuit (440), and a controller (444), which is set up in such a way that, by means of the electronic signal attenuation circuit (440) in a transmission mode of the near-field communication device (400) for transmitting a signal by means of the antenna (302), a lower impedance is applied to the receiving port (307) for attenuating a signal at the receiving port ( 307) than in a reception mode of the near-field communication device (400).
