The present invention discloses a smart card simultaneously having two read-write mode matrixes, comprising an antenna layer and an antenna and a chip circuit layer arranged on the antenna layer, and the antenna and the chip circuit layer are electrically connected through an elastic conductive device. The present invention also provides a production process of the above-mentioned smart card simultaneously having two read-write mode matrixes, comprising the following steps: burying the antenna on the back surface or facade of the antenna layer; after burying the antenna on the antenna layer, respectively adding a pad layer, a printing layer and a protection layer on the upper and lower parts of the antenna layer, and laminating to obtain a card matrix carrier; cutting a card from the laminated integral card matrix carrier to finally obtain a card matrix, and milling grooves on the obtained card matrix; and finally packaging. According to the smart card simultaneously having two read-write mode matrixes provided by the present invention, the antenna and the chip circuit layer are electrically connected by the elastic conductive device while needing no such manual operations as tin soldering and the like, thereby improving the production efficiency. Since the milling cutter provided with the special sensor is used for milling grooves, the product quality is ensured, the yield is high and the stability of the produced smart card is good. |
