Abstract:
A method for making a contact type smart card comprising a top layer in which an electrical sensing device resides, a core layer and a bottom layer, said method comprising:(1) coating a layer of primer and/or adhesive on the underside of the electrical sensor device such that said layer of primer/adhesive will come into direct physical contact with a thermosetting polymeric material that forms the core layers of the smart card;(2) positioning the electrical sensor device in an opening in the top layer;(3) positioning the top layer and bottom layer in a mold set up that defines a void space between the top layer and the bottom layer;(4) injecting a thermosetting polymeric material into the void space under conditions such that the primer/adhesive comes into direct physical contact with the thermosetting polymeric material to form a unified precursor smart card body;(5) removing the unified precursor smart card body from the mold set up; and(6) trimming the precursor smart card to a desired dimension to produce a smart card.
