Abstract
The present invention provides for a prelam body of a smart card, a smart card, a method of forming a prelam body of a smart card, and a method of forming a smart card. In accordance with some embodiments herein, a prelam body comprises a base substrate formed of at least one layer, and at least one overlay sheet layer formed on one side of the base substrate, wherein the at least one overlay sheet layer has a recess formed therein. The recess is at least partially extending through the at least one overlay sheet layer such that an opening of the recess is exposed.
Claims21
A prelam body of a smart card, comprising:
- a base substrate formed of at least one layer of thermoplastic material;
- at least one overlay sheet layer formed of thermoplastic material and on one side of the base substrate over a surface of the base substrate;
- and
- a security feature including a window feature formed of a recess,
- wherein the at least one overlay sheet layer has a recess formed therein, the recess at least partially extending through the at least one overlay sheet layer on the one side of the base substrate and at most onto the surface of the base substrate such that an opening of the recess is exposed.
A smart card, comprising:
- a prelam body comprising a base substrate formed of at least one layer of thermoplastic material;
- at least one overlay sheet layer formed of thermoplastic material and on one side of the base substrate over a surface of the base substrate;
- and
- a security feature including a window feature formed of a recess,
- wherein the at least one overlay sheet layer has a recess formed therein, the recess at least partially extending through the at least one overlay sheet layer on the one side of the base substrate and at most extending onto the surface of the base substrate such that an opening of the recess is exposed;
- and
- at one additional layer covering the at least one overlay sheet layer formed on one side of the prelam body,
- wherein the recess in the at least one overlay sheet layer is at least partially filled with material of the base substrate and/or with material of the at least one additional layer.
A method of forming a prelam body of a smart card, the method comprising:
- preparing a base substrate comprising at least one layer of thermoplastic material;
- forming at least one overlay sheet layer of thermoplastic material and on one side of the base substrate for covering one surface of the base substrate with the at least one overlay sheet layer;
- and
- forming a security feature including a window feature by forming a recess in the at least one overlay sheet layer, the recess at least partially extending through the at least one overlay sheet layer and at most onto the surface of the base substrate such that an opening of the recess is exposed.
A method of forming a smart card, the method comprising:
- providing the prelam body of the smart card, wherein the prelam body comprises a base substrate formed of at least one layer of thermoplastic material, and at least one overlay sheet layer formed on one side of the base substrate over a surface of the base substrate, wherein the at least one overlay sheet layer has a security feature including a window feature formed of a recess formed therein, the recess at least partially extending through the at least one overlay sheet layer on the one side of the base substrate and at most onto the surface of the base substrate such that an opening of the recess is exposed;
- and
- forming a stacked body configuration by mounting at least one additional layer to the one side of the base substrate for covering the at least one overlay sheet layer of the prelam body.
