Abstract: A laminated core stock sheet for use in a composite laminate assembly that is separated into individual cards is provided. The sheet includes a core substrate layer and an intermediate filmic layer coupled to the core substrate layer. The intermediate filmic layer includes a conductive material that provides a security, decorative, or functional feature of the cards. The core substrate layer and the intermediate filmic layer are coupled with another laminated core stock sheet to form the composite laminate assembly. The conductive material has a small thickness within the intermediate filmic layer such that the intermediate filmic layer prevents conduction of electrostatic discharge (ESD) through the intermediate filmic layer and outside of the individual cards.

Abstract: A card assembly includes an insulating planar body and a magnetic stripe assembly coupled with the planar body. The magnetic stripe assembly includes a magnetic layer configured to magnetically store information and a metal layer that provides at least one of a security feature, a decorative feature, or other functional feature. The metal layer has a small thickness such that the metal layer prevents conduction of electrostatic discharge (ESD) through the magnetic stripe assembly.
