Abstract
A method of making smart cards with an encapsulant (23) without having a bulge by heat lamination is disclosed. The core material (21) is cut for the encapsulant (23), such as a sensor or electronic component and laminated with a bottom layer (24) to create a cavity (22). The encapsulant (23) is introduced in the cavity (22) and laminated with another layer (27).
Claims22
A multi-layer smart card comprising a top layer, a core layer having at least one cavity, an encapsulant in said cavity, a bottom layer and adhesive layers between said top layer and said core layer and between said core layer and said bottom layer.
A process of making smart cards by inserting an encapsulant in a cavity of a core layer, sandwiching said core layer between a top layer and a bottom layer and laminating with adhesives.
A process of making a smart card comprising the steps of:
- providing a core layer with a cavity;
- providing a bottom layer;
- laminating said bottom layer to said core layer;
- inserting an encapsulant is said cavity;
- and
- laminating a top layer to said core layer.
A process of making a smart card comprising:
- providing a first layer;
- providing a second layer wherein said second layer has at least one cavity;
- providing a third layer;
- inserting an encapsulant in said cavity;
- placing said first layer, said second layer and said third layer in layered relationship;
- and
- fusing said layered relationship to form said smart card.
