description The invention discloses a method and device for shielding radio frequency communication, and belongs to the technical field of radio frequency. According to the method and the device for shielding radio frequency communication, the interference signal in the preset format can be actively sent to shield normal near field communication, so that the effect of shielding near field communication is effectively improved; in addition, the reading instruction of the card reader can be identified, so that the interference signal corresponding to the protocol type of the reading instruction is generated, and the effectiveness of the interference signal is improved. 本发明公开了屏蔽射频通信方法及装置，属于射频技术领域。本发明的屏蔽射频通信方法及装置能够主动发送预设格式的干扰信号，以屏蔽正常的近场通信，有效的提高的屏蔽近场通信的效果；本发明还能识别读卡器的读取指令，以便于生成与读取指令的协议类型对应的干扰信号，从而提高干扰信号的有效性。
