The invention relates to the field of induction devices, and especially relates to an elevator NFC card swiping induction device. The induction device comprises a mirror board, an NFC coil, a frame body and a connecting wire, the NFC coil is fixed between the frame body and the mirror board, the NFC coil is connected to a control main board through the connecting wire, the frame body is made of metal, a wave absorbing material is fixed to the bottom of the frame body, the wave absorbing material is attached to the front face and the back face of the frame body, and the connecting wire is coaxial. The metal is used as the material of the frame body, so that durability and attractiveness are improved. Magnetic field interference is reduced through the wave absorbing material. The coaxial line is used as the connecting wire of the NFC coil and the control main board, so that signal loss is reduced.

    本发明涉及感应装置领域,尤其是电梯NFC刷卡感应装置。该感应装置包括镜面板、NFC线圈、框体和连接线,NFC线圈固定在框体和镜面板之间,NFC线圈通过连接线连接在控制主板上,所述框体为金属材质,框体底部固定有吸波材,框体的正反两面均贴合有吸波材,连接线为同轴线。本发明使用金属作为框体的材质增加耐用度及美观性。通过吸波材来减少磁场干扰。通过使用同轴线作为NFC线圈与控制主板的连接线,来减少信号的损失。
