Smart card simultaneously having two read/write modes and method for producing same

摘要

A smart card with two read-write modes includes antenna layer, and an antenna and a chip module circuits on the antenna layer, wherein the antenna and the chip module circuit are electrically connected via an elastic conductive device. The invention also provides a manufacturing method of the aforesaid smart card with two read-write modes, which includes steps of: embedding an antenna on a back side or a front side of an antenna layer; after completing embedding on the antenna layer, add bedding sheets, printed sheets and protection films respectively above and underneath the antenna layer, then laminating to obtain a card base carrier; cutting card from the treated whole-sheet card base carrier to obtain a card base, and milling slots on the obtained card base, then finally encapsulating.
