SMART CARD SIMULTANEOUSLY HAVING TWO READ/WRITE MODE MATRIXES AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a smart card simultaneously having two read/write mode matrixes comprising an antenna layer an antenna disposed on the antenna layer and a chip circuit layer. The antenna and the chip circuit layer are electrically connected through an elastic conductive device. The present invention further provides a process for producing a smart card simultaneously having two read/write mode matrixes comprising the following steps: embedding an antenna at a rear surface or a front surface of an antenna layer; after the antenna is embedded on the antenna layer adding a cushion layer a printing layer and a protection layer on the antenna layer and under the antenna layer respectively and performing lamination to obtain a card matrix carrier; cutting the laminated entire card matrix carrier to eventually obtain a card matrix and milling a groove for the obtained card matrix; and performing the final packaging. The present invention uses an elastic conductive device to electrically connect an antenna and a chip circuit layer so that manual operations such as tin spot welding are not required the production efficiency is enhanced; as a milling cutter with a special sensor is used to mill a groove so the quality of products is ensured the product rate is high and the produced smart card is stable.
